The kind of glass that is Si, O, Na, B, Al no plastic, no visible change, that will shatter to high impact is 1. Pyrex glass.
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
Answer:
0.0522 mol NaSo4
Explanation:
3.148 x 10^22 Formula units NaSo4 * 1 mol NaSo4 / 6.02 x 10^23 Formula units NaSo4 = 0.0522 mol NaSo4
