The concentration of solution in mass percent is 60%.

Mass percentage refer to the percentage of solute present in solution.

The concentration of substance can be expressed in mass percent.

So, we can write,

Mass percent = mass of solute / mass of solution x 100.

Mass of solution = mass of solute + solvent.

Here, sucrose is the solute and water is solvent.

Mass of solute is 1.5Kg and mass of solvent is 1Kg.

Mass of solution = 1.5 + 1 = 2.5 Kg.

Mass percent = 1.5/2.5x100

So, Concentration of solution in mass percent = 60%.

Explanation:

Answer:

The correct answer is 10.939 mol ≅ 10.94 mol

Explanation:

According to Avogadro's gases law, the number of moles of an ideal gas (n) at constant pressure and temperature, is directly proportional to the volume (V).

For the initial gas (1), we have:

n₁= 1.59 mol

V₁= 641 mL= 0.641 L

For the final gas (2), we have:

V₂: 4.41 L

The relation between 1 and 2 is given by:

n₁/V₁ = n₂/V₂

We calculate n₂ as follows:

n₂= (n₁/V₁) x V₂ = (1.59 mol/0.641 L) x 4.41 L = 10.939 mol ≅ 10.94 mol

The number of moles is 10.94 mol.

The calculation is as follows:

The following formula should be used:

\(n_1\div V_1 = n_2\div V_2\\\\n_2= (n_2\div V_1) \times V_2\\\\ = (1.59 mol\div 0.641 L) \times 4.41 L\)

= 10.939 mol

= 10.94 mol

Therefore we can conclude that the number of moles is 10.94 mol.

Answer:

6598 mL = 6598 cm^3

Explanation:

Cubic centimeters (cc) and milliliters (mL) are both units of volume measurement. They are equivalent, meaning that 1 mL is equal to 1 cm^3. To convert from mL to cm^3, we simply multiply the volume in mL by 1.

To convert 6598 mL to cubic centimeters, we can use this conversion factor:

1 mL = 1 cm^3

Therefore, we can multiply 6598 mL by 1 to get the equivalent volume in cubic centimeters.

6598 mL x 1 cm^3/mL = 6598 cm^3

So, 6598 mL is equal to 6598 cm^3.

Step 2: Calculate the moles corresponding to 4 kg (4000 g) of C₂H₆O

The molar mass of C₂H₆O is 46.07 g/mol.

4000 g × 1 mol/46.07 g = 86.82 mol

Step 3: Calculate the moles of CO₂ released

86.82 mol C₂H₆O × 2 mol CO₂/1 mol C₂H₆O = 173.6 mol CO₂

Step 4: Calculate the mass corresponding to 173.6 moles of CO₂

The molar mass of CO₂ is 44.01 g/mol.

173.6 mol × 44.01 g/mol = 7640 g = 7.640 kg

Explanation:

Answer:

a constellation on the equator east of Taurus represented on charts by the figure of a hunter with belt and sword. 2 : a giant hunter slain by Artemis in Greek mythology

Orion constellation is one of the brightest and best known constellations in the night sky. It lies on the celestial equator. Orion has been known since ancient times. The constellation is also known as the Hunter, as it is associated with one in Greek mythology.

By using the ideal gas law and Avogadro's number, we find that there are approximately 6.72 × 10^22 molecules of CO2 in 2.5 L at STP.

To determine the number of molecules of CO2 in 2.5 L at STP (Standard Temperature and Pressure), we can use the ideal gas law and Avogadro's number.

Avogadro's number (N_A) is a fundamental constant representing the number of particles (atoms, molecules, ions) in one mole of substance. Its value is approximately 6.022 × 10^23 particles/mol.

STP conditions are defined as a temperature of 273.15 K (0 °C) and a pressure of 1 atmosphere (1 atm).

First, we need to convert the volume from liters to moles of CO2. To do this, we use the ideal gas law equation:

PV = nRT,

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

Since we have STP conditions, we can substitute the values:

(1 atm) × (2.5 L) = n × (0.0821 L·atm/(mol·K)) × (273.15 K).

Simplifying the equation:

2.5 = n × 22.4149.

Solving for n (the number of moles):

n = 2.5 / 22.4149 ≈ 0.1116 moles.

Next, we can calculate the number of molecules using Avogadro's number:

Number of molecules = n × N_A.

Number of molecules = 0.1116 moles × (6.022 × 10^23 particles/mol).

Number of molecules ≈ 6.72 × 10^22 molecules.

Therefore, there are approximately 6.72 × 10^22 molecules of CO2 in 2.5 L at STP.

metallic bonds

Explanation:

atoms in a metallic solid loose their outer electrons and form a regular lattice of positive metallic ions.

The chemical bondings are present between the atoms due to the attractive forces. The bond shown in the diagram represents the metallic bonds. Thus, option A is correct.

A metallic bond is a chemical bonding present due to the electrostatic attractive forces present between the delocalized electrons and the ions of the metals.

The metal produces cations that bond with the electrons delocalized around them. This type of bonding accounts for the malleability and conductivity of the metallic species.

The delocalized electrons are shared by the positively charged metal ions. The cations are largely spread in space. It is seen in the elements of aluminum, magnesium, copper, sodium, zinc, calcium, etc.

The formula of the hydrate is NiCl2·4.27H2O. The name of the hydrate is nickel (II) chloride tetrahydrate.

To determine the formula and name of the hydrate, we need to first find the value of "x" in the formula NiCl2·xH2O using the given information.

Mass of water = Initial mass - Mass of anhydrous salt

Mass of water = 0.470 g - 0.256 g

Mass of water = 0.214 g

The molar mass of H2O is 18.015 g/mol, so the number of moles of water present in the hydrated salt can be calculated as:

Moles of water = Mass of water / Molar mass of water

Moles of water = 0.214 g / 18.015 g/mol

Moles of water = 0.0119 mol

The number of moles of anhydrous salt can be calculated by dividing its mass by its molar mass:

Moles of anhydrous salt = Mass of anhydrous salt / Molar mass of anhydrous salt

Moles of anhydrous salt = 0.256 g / (Ni: 58.69 g/mol + 2Cl: 2 x 35.45 g/mol)

Moles of anhydrous salt = 0.00279 mol

The ratio of moles of water to moles of anhydrous salt is equal to "x" in the formula NiCl2·xH2O:

Moles of water / Moles of anhydrous salt = x

0.0119 mol / 0.00279 mol = x

x ≈ 4.27

Therefore, the formula of the hydrate is NiCl2·4.27H2O. The name of the hydrate is nickel (II) chloride tetrahydrate.

Same reason as the person above me

The order of the alternatives from largest to lowest atomic radius is K > Na > \(\rm Na^+\) > \(\rm K^+\).

The atomic radius usually decreases from left to right across the periodic table due to increasing effective nuclear charge, which attracts electrons more strongly and reduces the atomic radius. As a result, among the options offered K (potassium) has the largest atomic radius. Because the atomic radius shrinks from left to right, K (potassium) has a larger atomic radius than Na (sodium).

In addition, when an atom loses an electron to become an ion, its radius decreases. As a result, the \(\rm Na^+\) ion has a smaller radius than Na. The radius of potassium ion is greater than that of sodium ion because potassium is in the same period as sodium but is one group to the left, resulting in a larger atomic radius.

Answer:

2.109 atm

Explanation:

This is Gay-Lussac's Law when the temperature of a sample of gas in a rigid container is increased, the pressure of the gas increases as well. The increase in kinetic energy results in the molecules of gas striking the walls of the container with more force, resulting in a greater pressure. Gay-Lussac's Law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant. Gay-Lussac's Law is very similar to Charles's Law, with the only difference being the type of container.

So for this one:

\(\frac{P_{1} }{T_{1}} =\frac{P_{2} }{T_{2}}\)

Rearrange it to

P2= (P1 x T2)/T1

P2= (450 x 1.5)/320 = 2.109 atm

Answer:

The volume of Component 1 is 36 cubic inches.

Explanation:

To calculate the volume of a composite solid, we need to determine the individual volumes of the different components and then add them together.

In this case, the composite solid consists of multiple components with the following dimensions:

Component 1:

Length: 4 inches

Width: 3 inches

Height: 3 inches

To find the volume of Component 1, we multiply the length, width, and height together:

Volume of Component 1 = Length x Width x Height = 4 in x 3 in x 3 in = 36 cubic inches

Therefore, the volume of Component 1 is 36 cubic inches.

Please provide the dimensions of the remaining components of the composite solid, and I will calculate the total volume by summing up the individual volumes.

At equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

1: Write the balanced chemical equation:

\(C_O\)(g) + \(Cl_2\)(g) ⟶ \(C_OCl_2\)(g)

2: Set up an ICE table to track the changes in moles of the substances involved in the reaction.

Initial:

\(C_O\)(g) = 0.3500 mol

\(Cl_2\)(g) = 0.05500 mol

\(C_OCl_2\)(g) = 0 mol

Change:

\(C_O\)(g) = -x

\(Cl_2\)(g) = -x

\(C_OCl_2\)(g) = +x

Equilibrium:

\(C_O\)(g) = 0.3500 - x mol

\(Cl_2\)(g) = 0.05500 - x mol

\(C_OCl_2\)(g) = x mol

3: Write the expression for the equilibrium constant (Kc) using the concentrations of the species involved:

Kc = [\(C_OCl_2\)(g)] / [\(C_O\)(g)] * [\(Cl_2\)(g)]

4: Substitute the given equilibrium constant (Kc) value into the expression:

1.2 x \(10^3\) = x / (0.3500 - x) * (0.05500 - x)

5: Solve the equation for x. Rearrange the equation to obtain a quadratic equation:

1.2 x \(10^3\) * (0.3500 - x) * (0.05500 - x) = x

6: Simplify and solve the quadratic equation. This can be done by multiplying out the terms, rearranging the equation to standard quadratic form, and then using the quadratic formula.

7: After solving the quadratic equation, you will find two possible values for x. However, since the number of moles cannot be negative, we discard the negative solution.

8: The positive value of x represents the number of moles of \(Cl_2\)(g) at equilibrium. Substitute the value of x into the expression for \(Cl_2\)(g):

\(Cl_2\)(g) = 0.05500 - x

9: Calculate the value of \(Cl_2\)(g) at equilibrium:

\(Cl_2\)(g) = 0.05500 - x

\(Cl_2\)(g) = 0.05500 - (positive value of x)

10: Calculate the final value of \(Cl_2\) (g) at equilibrium to get the answer.

Therefore, at equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

Explanation:

Answer:

C: 40.

Explanation:

To answer this question, we need to use the concept of heat transfer and the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed from one form to another.

When two substances are in contact, heat can flow from one substance to another until they reach thermal equilibrium (i.e., they have the same temperature). In this case, Substance 1 loses 40 calories of heat, which means it gives off 40 calories of heat to Substance 2. Therefore, Substance 2 will gain 40 calories of heat to reach thermal equilibrium.

Therefore, the correct answer is option C: 40.

Answer: The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
