Potassium chlorate decomposes into potassium chloride and oxygen gas. How many grams of oxygen are produced when 1.06 grams of p
kifflom [539]

The amount of oxygen that are produced when 1.06 grams of potassium chlorate decompose completely is 0.64 grams.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

  • n = W/M, where
  • W = given mass
  • M = molar mass

Moles of potassium chlorate = 1.66g / 122.5g/mol = 0.0135mole

Given chemical reaction is:

2KClO₃ → 2KCl + 3O₂

From the stoichiometry of the reaction, it is clear that:

2 moles of KClO₃ = produces 3 moles of O₂

0.0135 moles of KClO₃ = produces (3/2)(0.0135)=0.02 moles of O₂

Mass of oxygen = (0.02mol)(32g/mol) = 0.64 g

Hence produced mass of oxygen is 0.64 grams.

Table B: Enthalpy of Formation of Reactants and Products
Inessa [10]

The calculated enthalpy values are as follows:

  • Total enthalpy of reactants = -103.85 KJ/mol
  • Total enthalpy of products = -2057.68 KJ/mol
  • Enthalpy of reaction = -1953.83 kJ/mol

<h3>What is the enthalpy of the reaction?</h3>

The enthalpy of the reaction is determined as follows:

  • Enthalpy of reaction = Total enthalpy of products -Total enthalpy of reactants
  • Total enthalpy of reactants = (ΔHf of Reactant 1 x Coefficient) + (ΔHf of Reactant 2 x Coefficient)
  • Total enthalpy of products= (ΔHf of Product 1 x Coefficient) + (ΔHf of Product 2 x Coefficient)

Equation of reaction equation: C₃H₈ (g) + 5 O(g) → 4 H₂O(g) + 3CO₂(g)

Total enthalpy of reactants = (-103.85 * 1) + (0 * 5)

Total enthalpy of reactants = -103.85 + 0

Total enthalpy of reactants = -103.85 KJ/mol

Total enthalpy of products = (-393.51 * 4) +(-241.82 * 3)

Total enthalpy of products = (-1574.04) + (-483.64)

Total enthalpy of products = -2057.68 KJ/mol

Enthalpy of reaction =  -2057.68 KJ/mol -(-103.85 KJ/mol)

Enthalpy of reaction = -1953.83 kJ/mol

In conclusion, the enthalpy of the reaction is determined from the difference between the total enthalpy of products and reactants.
