Answer:

national

Explanation:

I don't understand, I'm sorry

Answer:

220g of CO2

Explanation:

Step 1:

The balanced equation for the reaction.

2C5H11OH + 15O2 —> 10CO2 + 12H2O

Step 2:

Determination of the number of mole of CO2 produced by burning 1 mole of C5H11OH.

From the balanced equation above,

2 moles of C5H11OH produced 10 moles CO2.

Therefore, 1 mole of C5H11OH will produce = (1 x 10)/2 = 5 moles of CO2.

Therefore, 5 moles of CO2 is produced from the reaction.

Step 3:

Conversion of 5 moles of CO2 to grams.

Molar mass of CO2 = 12 + (2x16) = 44g/mol

Number of mole of CO2 = 5 moles

Mass of CO2 =...?

Mass = mole x molar mass

Mass of CO2 = 5 x 44

Mass of CO2 = 220g.

Therefore, 220g of CO2 were obtained from the reaction.

Answer:

I think the density of the object determines if it floats or sinks

The density of the salt is 2915 kg/dm³.

To determine the density of the salt, we need to calculate the volume of the salt and then divide the mass of the salt by this volume. The volume of the salt can be found by subtracting the initial volume of oil in the graduated cylinder from the final volume after the salt was added. In this case, the initial volume was 4.02 mL and the final volume was 4.22 mL, so the volume of the salt is 0.20 mL.

To convert this volume to dm³, we multiply by the conversion factor 10^-3, resulting in 0.20 x 10^-3 dm³. Finally, we divide the mass of the salt (0.583 g) by the volume (0.20 x 10^-3 dm³) to find the density, which is 2915 kg/dm³.

Therefore, the density of the salt is determined to be 2915 kg/dm³.

Answer:

The reaction is endothermic

Explanation:

we know that the reactants had to get energy from its surroundings which means that the reaction is endothermic

The equilibrium constant kc, she obtained for this reaction is 5.7×10⁻⁴.

The amount of reactant to product in a chemical reaction can be compared to determine the equilibrium constant, which is used to predict chemical behavior. The rate constants are fixed at some temperature.

The rate constant for the forward reaction divided by the rate constant for the reverse reaction is the equilibrium constant.

Balanced reaction,

COCl₂(g)  ↔ CO(g) + Cl₂(g)

The equilibrium COCl₂ = 1.57M (volume is 1L hence concentration is M)

1.6 - x = 1.57

so, x = 1.57 - 1.6

x = -0.03M

Thus, Kc = x²/1.6 - x

Kc = 0.0009/1.57

Explanation:

took the test

it said that it was wrong but then it also said the total bond energy of the reactants is 677 kJ/mol. the correct one was 854, i guess.

Hydrogen and chlorine gases react to produce hydrochloric acid according to the reaction. 677 kJ/mol total bond energy  is in the products of the reaction. Therefore, option A is correct.

Bond strength in a chemical bond is measured by bond energy, often known as mean bond enthalpy or average bond enthalpy. According to IUPAC, bond energy is the average bond-dissociation energy in the gas phase for all bonds of the same type within a single chemical species.

In a chemical reaction, links between molecules are destroyed, and new bonds are created to create new molecules. For instance, hydrogen and oxygen are created when the bonds between two molecules of water are broken.

The quantity of bonds between atoms affects bond energy. A double bond, which consists of a single bond and an additional bond, is stronger than a single bond despite the fact that they are both weaker than each other.

Thus, 677 kJ/mol total bond energy, so option A is correct.

No they are not, as climate is long term conditions for an area while weather is temporary

Therefore, the temperature change in the water due to the sheer drop of 543ft is approximately 76.7°F.

The steady flow energy equation is given by the expression;

(P/γ) + (v²/2g) + Z = constant

Where P/γ is the pressure energy, v²/2g is the kinetic energy, and Z is the potential energy.

Since the flow of the water is steady, we can assume that the total energy at the top of the falls is equal to the total energy at the bottom of the falls.

Consider the top of the waterfall, where the potential energy is 0, and the water is at the initial temperature T1.

At the bottom of the waterfall, the kinetic energy is negligible compared to the potential energy.

Therefore, the energy equation can be simplified as;

0 + (v²/2g) + Z₂ = (P/γ) + 0 + Z₁

Where Z₂ is the elevation of the bottom of the waterfall, and Z₁ is the elevation of the top of the waterfall.

Assuming that the water temperature at the bottom of the waterfall is T2, we can calculate the temperature change in the water as;

T₂ - T₁ = (v²/2Cp)

where Cp is the specific heat of water.

To estimate the velocity of the water at the bottom of the falls, we can use the Bernoulli's equation, which relates the pressure energy and kinetic energy of the water.

P₁/γ + v₁²/2g = P₂/γ + v₂²/2g

where P₁ is the pressure at the top of the waterfall, P₂ is the pressure at the bottom of the waterfall, v₁ is the velocity of the water at the top of the waterfall, and v₂ is the velocity of the water at the bottom of the waterfall.

Since the waterfall is open to the atmosphere, we can assume that the pressure at the top and bottom of the waterfall is atmospheric pressure

(P₁ = P₂ = Patm).

Therefore, the Bernoulli's equation can be simplified as;

v₂²/2g = v₁²/2g + Z₂ - Z₁

The height of the waterfall is 543ft, which is equal to 165.5m.

Using this value, we can estimate the velocity of the water at the bottom of the waterfall as;

v₂²/2g = v₁²/2g + 165.5m

Solving for v₂, we get;

v₂ = √(v₁² + 2g*165.5m)

Substituting this value in the expression for temperature change, we get;

T₂ - T₁ = (v₁² + 2g*165.5m)/2Cp

Now, let's estimate the velocity of the water at the top of the waterfall. According to the information given in the problem, the waterfall has a sheer drop, which means that the water falls freely without any obstruction.

Therefore, we can assume that the water at the top of the waterfall is at rest, and the velocity at the bottom of the waterfall is equal to the free-fall velocity of an object dropped from a height of 543ft, which can be estimated using the equation;

v = √(2gh)

where h is the height of the fall. Substituting the values, we get;

v = √(2*9.81m/s²*165.5m)

v = 57.4m/s

Therefore, the temperature change in the water can be estimated as;

T₂ - T₁ = (57.4m/s)²/2Cp + 2*9.81m/s²*165.5m)/2Cp

T₂ - T₁ = 42.6°C or 76.7°F

Explanation:

Two approaches to calculate the number of carbon monoxide molecules in 45 pg are using Avogadro's number or molar mass.

1) Approach using Avogadro's number:

Determine the molar mass of carbon monoxide (CO). The molar mass of carbon is approximately 12.01 g/mol, and the molar mass of oxygen is approximately 16.00 g/mol. Therefore, the molar mass of carbon monoxide (CO) is: 12.01 g/mol (carbon) + 16.00 g/mol (oxygen) = 28.01 g/mol

Convert the given mass of carbon monoxide to moles. 45 pg = 45 x 10⁻¹² g (since 1 pg = 10⁻¹²  g) moles = mass / molar mass moles = 45 x 10⁻¹²  g / 28.01 g/mol

Calculate the number of molecules using Avogadro's number. Avogadro's number states that there are 6.022 x 10²³ molecules in one mole of a substance. Number of molecules = moles x Avogadro's number of molecules = (45 x 10⁻¹²  g / 28.01 g/mol) x (6.022 x 10²³ molecules/mol)

Approach using molar mass

Determine the molar mass of carbon monoxide (CO). The molar mass of carbon monoxide (CO) is calculated as 28.01 g/mol (as explained in Approach 1).

Convert the given mass of carbon monoxide to moles. 45 pg = 45 x 10⁻¹² g (since 1 pg = 10⁻¹²  g) moles = mass / molar mass moles = 45 x 10⁻¹²  g / 28.01 g/mol

Use stoichiometry to calculate the number of molecules. The balanced chemical equation for carbon monoxide (CO) is: 1 mole of CO = 6.022 x 10²³molecules of CO

Since the stoichiometry is 1:1, the number of molecules is equal to the number of moles. Number of molecules = 45 x 10⁻¹²  g / 28.01 g/mol

Both approaches involve using the molar mass of carbon monoxide and Avogadro's number to convert mass to moles and then to molecules.
