4.08g of iron(II) chloride is dissolved in 50. mL of a 0.60 M aqueous solution of silver nitrate. Calculate the final molarity of chloride anion in the solution. you can assume the volume of the solution doesn't change when the iron(II) chloride is dissolved in it.

Answers

Answer 1

The final concentration of the chloride ions is  0.32 M.

What is the final molarity of the chloride ion?

We know that we have to obtain the number of moles of the iron II chloride that was reacted in the solution and then we would have;

Number of moles of iron II chloride = 4.08g /127 g/mol = 0.032 moles

Given the fact that there are two chloride ions hence the amount of the chloride ions is 0.016 moles

The concentration of the silver nitrate = 50/1000  *  0.60 M

= 0.03 moles

Thus we would have a final concentration of 0.016 moles/ 0.05

= 0.32 M

Help pls is you cant read it it says place the processes of sedimentary rock formation in the order in

Answers

Answer:

Weathering ➡️ Erosion ➡️ Deposition ➡️ Compaction ➡️ Cementation

Explanation:

The processes of sedimentary rock formation involves:

1. Weathering: The preexisting rocks are weathered through abrasion caused by sand-blasting and other weathering processes. This breaks down the rocks into smaller pieces.

2. Erosion: Erosion acts as an agent of transportation of the weathered products. The sediments that are weathered are transported through erosion. The flowing or flooding water carries them to where they are deposited.

3. Deposition: The weathered materials are eroded and deposited layer upon layer. This happens when there is nothing that can move them away again.

4. Compaction: The sedimentation continues as the deposited sediments become increasingly overburden. They begin to compact together and closing down pore spaces.

5. Cementation: The dissolved minerals begin to form mineral crusts through precipitation or crystallization. This gradually cements the sediments to form a rock.

HEY!!! I NEED SOME HELP<3A chemist reacted 57.50 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is shown.Na + Cl2 → NaClIf the percentage yield of the reaction is 86%, what is the actual yield? Show your work, including the use of stoichiometric calculations and conversion factors.

Answers

ANSWER

The actual yield is 125.646 grams

STEP-BY-STEP EXPLANATION

Given information

The mass of sodium in grams = 57.50 grams

The percentage yield = 86%

The next step is to write the balanced equation of the reaction

\(2Na_{(s)}+Cl_{2(g)}\text{ }\rightarrow2NaCl_{(aq)}\)

From the above reaction, we can see that 2 moles of sodium react with 1 mole of chloride too give moles of sodium chloride

The next step is to find the number of moles sodium using the below formula

\(\text{mole = }\frac{\text{ mass}}{\text{ molar mass}}\)

According to the periodic table, the molar mass of sodium is 23 g/mol

\(\begin{gathered} \text{mole = }\frac{57.50}{23} \\ \text{mole = }2.5\text{ moles} \end{gathered}\)

The next step is to find the number of moles of sodium chloride using a stoichiometry ratio

From the above reaction, you can see that 2 moles of sodium react to give 2 moles of sodium chloride

Let x represents the number of moles of sodium chloride

\(\begin{gathered} 2\text{ moles }\rightarrow\text{ 2 moles} \\ 2.5\text{ moles }\rightarrow\text{ x moles} \\ \text{cross multiply} \\ 2\text{ }\times\text{ x = 2 }\times\text{ 2.5} \\ 2x\text{ = 5} \\ \text{Divide both sides by 2} \\ \frac{\cancel{2}x}{\cancel{2}}\text{ = }\frac{5}{2} \\ x\text{ = 2.5 moles} \end{gathered}\)

Therefore, the number of moles of NaCl is 2.5 moles

The next step is to find the theoretical yield using the below formula

\(\text{mole = }\frac{\text{ mass}}{\text{ molar mass}}\)

According to the periodic table, the molar mass of NaCl is 58.44 g/mol

\(\begin{gathered} 2.5\text{ = }\frac{mass}{58.44} \\ \text{cross multiply} \\ \text{mass = 2.5 }\times\text{ 58.44} \\ \text{mass = 146.1 grams} \end{gathered}\)

Since the theoretical yield is 146.1 grams, then we can now find the actual yield using the below formula

\(\begin{gathered} \text{Percentage yield =}\frac{actual\text{ yield}}{\text{theoretical yield}} \\ \end{gathered}\)

Recall that, the percentage yield is86%

\(\begin{gathered} \frac{86}{100}\text{ = }\frac{actual\text{ yield}}{146.1} \\ 0.86\text{ = }\frac{actual\text{ yield}}{146.1} \\ \text{cross multiply} \\ \text{actual yield = 0.86 }\times\text{ 146.1} \\ \text{actual yield = 125.646 grams} \end{gathered}\)

Therefore, the actual yield is 125.646 grams

The heat that is absorbed by the system is  1363 J. Option B

What is the heat absorbed?

We know that in a chemical reaction that there could be the absorption or the evolution of heat. We say that there is the evolution of heat when heat has been lost from the system and there is the absorption of heat when heat has been gained by the system.

Number of moles of the barium hydroxide hydrate = 3.15 g/203 g/mol

= 0.015 moles

Number of moles of the ammonium thiocyanate = 1.52/76 g/mol

= 0.02 moles

If 1 mole of barium hydroxide hydrate reacts with 2 moles of  ammonium thiocyanate

0.015 moles of barium hydroxide hydrate reacts with 0.015 * 2 moles/1 mole

= 0.03 moles

Hence the limiting reactant is the ammonium thiocyanate.

Consider the combustion reaction between 25.0 mL of liquid methanol (CH3OH; d = 0.850 g/mL) and 12.5 L of oxygen gas measured at STP. The products of the reaction are CO2 (g) and H2O (g). Calculate the volume of liquid H2O formed if the reaction goes to completion and you condense the water vapor. (Assume that the density of water is 1.00 g/mL)

Answers

The volume of the water produced is obtained as 0.01422L.

What is the volume of water formed?

We know that a combustion reaction is one in which a substance is burnt in oxygen. When we burn the substance in oxygen, heat is evolved and this can be seen as a change in the temperature of the system.

Now;

We must find the number of moles of each of the reactants so that we can be able to determine the limiting reactant.

Volume of methanol =  25.0 mL

Density of methanol = 0.850 g/mL

Mass of methanol = Density * volume

= 0.850 g/mL * 25.0 mL

= 21.25 g

Number of moles of methanol= 21.25 g/32 g/mol

= 0.66 moles

Volume of oxygen = 12.5 L

If 22.4 L of oxygen is occupied by 1 mole

12.5 L  is occupied by 12.5 L  * 1 mole/22.4 L

= 0.59 moles

If 2 moles of methanol reacts with 3  moles of oxygen

0.66 moles of methanol reacts with  0.66 moles  * 3 moles/2 moles

= 0.99 moles

Hence oxygen is the limiting reactant.

If 3 moles of oxygen produces 4 moles of water

0.59 moles of oxygen produces 0.59 moles * 4 moles/ 3 moles

= 0.79 moles

Mass of water =  0.79 moles * 18 g/mol = 14.22 g

Volume of the water = mass/density

In the laboratory, a quantity of I2 was reacted with excess H2 to give 1.26 moles of HI. It is also known that the percent yield of this reaction was 84.0%. How many moles of I2 reacted

Answers

Answer:

1.008moles of iodine

Explanation:

Hello,

This question requires us to calculate the theoretical yield of I₂ or number of moles that reacted.

Percent yield = (actual yield / estimated yield) × 100

Actual yield = 1.2moles

Estimated yield = ?

Percentage yield = 84%

84 / 100 = 1.2 / x

Cross multiply and solve for x

100x = 84 × 1.2

100x = 100.8

x = 100.8/100

x = 1.008moles

1.008 moles of I₂ reacted in excess of H₂ to give 1.2 moles of HI

The number of moles of I2 reacted should be 1.008moles of iodine

Calculation of the number of moles:

We know that

Percent yield = (actual yield / estimated yield) × 100

Here

Actual yield = 1.2moles

Estimated yield =  x

And, Percentage yield = 84%

So,

84 / 100 = 1.2 / x

100x = 84 × 1.2

100x = 100.8

x = 100.8/100

x = 1.008moles

Therefore, The number of moles of I2 reacted should be 1.008moles of iodine

What would be the volume in liters of an 25.15 liter sample of gas at 201 °C and 2.31 atm if conditions were changed to STP?

Answers

The volume of the gas at STP would be 23.93 liters.

The volume of gas at STP (Standard Temperature and Pressure), we need to use the Ideal Gas Law, which states that PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature. First, we need to calculate the number of moles of gas in the initial sample. We can use the formula n = PV/RT, where P is the initial pressure, V is the initial volume, R is the gas constant, and T is the initial temperature.
n = (2.31 atm) x (25.15 L) / [(0.0821 L atm/mol K) x (201 + 273.15 K)]
n = 1.067 moles

Now, we can use the molar volume of gas at STP, which is 22.4 L/mol, to calculate the volume of gas at STP.
V = n x 22.4 L/mol
V = 1.067 moles x 22.4 L/mol
V = 23.93 L
Therefore, the volume of the gas at STP would be 23.93 liters.

Describe the advantages of the hydrogen-rich fuel cell when compared to the conventional electrochemical cells such as lead-acid battery. (4)​

Answers

The hydrogen-rich fuel cell offers advantages in terms of efficiency, environmental impact, operating time, refueling speed, weight, size, and lifespan when compared to conventional electrochemical cells like the lead-acid battery.

The hydrogen-rich fuel cell offers several advantages over conventional electrochemical cells like the lead-acid battery. Here are some of the key advantages:

1. Higher Efficiency: Hydrogen fuel cells have higher energy conversion efficiencies compared to lead-acid batteries. Fuel cells can convert chemical energy directly into electrical energy with minimal loss, while lead-acid batteries have inherent energy losses due to factors such as internal resistance and heat dissipation.

2. Clean and Environmentally Friendly: Hydrogen fuel cells produce electricity through the reaction of hydrogen and oxygen, with water being the only byproduct. They do not produce harmful emissions or contribute to air pollution, making them a cleaner and more sustainable power source compared to lead-acid batteries, which require the use of chemicals like sulfuric acid.

3. Longer Operating Time: Fuel cells have longer operating times compared to lead-acid batteries. Lead-acid batteries have a limited capacity and need to be recharged frequently, while fuel cells can continuously generate electricity as long as there is a supply of hydrogen.

4. Faster Refueling: Refueling a fuel cell is faster compared to recharging a lead-acid battery. Fuel cells can be refueled by replenishing the hydrogen supply, which can be done relatively quickly. In contrast, lead-acid batteries require a longer time to recharge, typically hours, depending on the battery's capacity and charging rate.

5. Lighter Weight and Compact Size: Hydrogen fuel cells have a higher energy density compared to lead-acid batteries, meaning they can store more energy in a smaller and lighter package. This makes fuel cells more suitable for applications where weight and space are critical, such as in portable devices or electric vehicles.

6. Longer Lifespan: Fuel cells generally have a longer lifespan compared to lead-acid batteries. Lead-acid batteries can experience degradation over time due to factors like sulfation, which can reduce their overall capacity and lifespan. Fuel cells, on the other hand, can provide consistent performance over an extended period with proper maintenance.

These advantages make fuel cells a promising technology for various applications, including transportation, stationary power generation, and portable electronics.

Which portion of a molecule of F2O has partial positive charge?
Question 3 options:

A)

B)

The central O atom

C)

The partial charge on each atom is zero

D)

The partial charge on each atom is negative

Answers

The partial charges on each fluorine atom are negative. Option B) The central O atom is the correct answer. Option B

The partial charges in a molecule are determined by the electronegativity values of the atoms involved. Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. In the case of \(F_2O\), fluorine (F) is more electronegative than oxygen.

Fluorine is the most electronegative element on the periodic table, meaning it has a high ability to attract electrons. Oxygen is also relatively electronegative but less so than fluorine. When fluorine atoms bond with oxygen, the shared electrons will be pulled more towards the fluorine atoms, creating a polar covalent bond.

In \(F_2O\), each fluorine atom will pull the shared electrons towards itself, resulting in a higher electron density around the fluorine atoms. This creates a region of partial negative charge around the fluorine atoms.

Conversely, the oxygen atom will have a region of lower electron density and, therefore, a partial positive charge. This is because the shared electrons spend more time around the fluorine atoms due to their higher electronegativity.

Option B

reaction will be spontaneous at all temperatures if _____

Answers

If a reaction has a negative ΔG and a positive ΔS, the reaction will be spontaneous at all temperatures.

If a reaction is spontaneous at all temperatures, it implies that the reaction will occur without the need for any external intervention, such as the addition of energy. For a reaction to be spontaneous, it must satisfy the criteria of thermodynamic favorability, which is determined by the change in Gibbs free energy (ΔG) associated with the reaction.

The relationship between ΔG, temperature (T), and the equilibrium constant (K) of a reaction is described by the equation ΔG = ΔH - TΔS, where ΔH is the change in enthalpy and ΔS is the change in entropy.

To ensure spontaneity at all temperatures, two conditions must be met:

ΔG must be negative: A negative ΔG indicates a thermodynamically favorable reaction, meaning the products have a lower Gibbs free energy than the reactants. If ΔG is negative, the reaction will proceed spontaneously in the forward direction.

ΔS must be positive: A positive ΔS signifies an increase in the overall entropy of the system. Higher entropy means more disorder, and spontaneous reactions often involve an increase in randomness. When ΔS is positive, it can compensate for the enthalpic term, ΔH, allowing the reaction to proceed spontaneously.

(2002) exposed one nostril of each of 12 non-detector participants to androstenone for short periods every day for 21 days. the other nostril was plugged and had humidified air flow to prevent androstenone from entering. after the 21 days, the researchers found that 9 participants had improved detection accuracy in the plugged nostril, whereas four had reduced accuracy. the author conducted a statistical hypothesis test of whether accuracy in fact did change after the exposure to steroid. let p refer to the portion of non-detectors in the population whose accuracy scores improve after 21 days. what is the p-value for the hypothesis test?
