If u can help answer these questions i’ll mark you brainliest, pls it’s due tomorrow

Explanation:

First Question:

The equation is given as;

2KClO3  --> 2KCl + 3O2

2 mol of KClO3  produces 2 mol of KCl

Converting 7.6 g of KCl to mol;

Number of moles = Mass / Molar mass = 7.6 / 74.5513  = 0.1019

2 mol = 2 mol

x mol = 0.1019

solving for x;

x = 0.1019 mol of KClO3

converting to mass;

Mass = Number of mol * Molar mass = 0.1019 * 122.55 = 12.48

Correct option = B. 12.5 g

Second Question

The equation is given as;

1N2 + 3H2 --> 2NH3

3 mol of H2  produces 2 mol of NH3

Converting 34.06g of NH3 to mol;

Number of moles = Mass / Molar mass = 34.06 / 17.031 = 2 mol

3 mol = 2 mol

x mol = 2 mol

Solving for x;

x = 6 / 2 = 3 mol of H2

Converting 3 mol H2 to g;

Mass = Number of moles * Molar mass = 3 * 2.016 = 6.048g

Correct option: B. 6.05g
