when 45 grams of copper (ii) carbonate are decomposed with heat how many grams of carbon dioxide will be produced

Answers

Answer 1

Answer:

16.02 g

Explanation:

the balanced equation for the decomposition of CuCO₃ is as follows

CuCO₃ --> CuO + CO₂

molar ratio of CuCO₃ to CO₂ is 1:1

number of CuCO₃ moles decomposed - 45 g / 123.5 g/mol = 0.364 mol

according to the molar ratio

1 mol of CuCO₃ decomposes to form 1 mol of CO₂

therefore 0.364 mol of  CuCO₃ decomposes to form 0.364 mol of CO₂

number of CO₂ moles produced - 0.364 mol

therefore mass of CO₂ produced - 0.364 mol x 44 g/mol = 16.02 g

16.02 g of CO₂ produced

The ratio of chlorine to hydrogen chloride in the reaction

H2(g) + Cl2 (g) -> 2 HCl(g) is

Answers

Answer:

1:2.

Explanation:

For the balanced reaction:

H₂(g) + Cl₂(g) → 2HCl(g),

1.0 mole of H₂(g) reacts with 1.0 mole of Cl₂(g) to produce 2.0 moles HCl(g),

∴ The ratio of chlorine (Cl₂(g)) to hydrogen chloride (HCl(g)) is 1:2.

Final answer:

The ratio of chlorine to hydrogen chloride in the balanced reaction H2(g) + Cl2 (g) -> 2 HCl(g) is 1:2. This ratio is derived from the coefficients in the balanced chemical equation.

Explanation:

In the balanced reaction H2(g) + Cl2 (g) -> 2 HCl(g), the ratio of chlorine (Cl2) to hydrogen chloride (HCl) is 1:2. This means that for every 1 mole of chlorine gas, 2 moles of hydrogen chloride are produced. The ratio does not represent the actual amount of substances, but rather the relative amounts of reactants and products based on their coefficients in the balanced equation.
