Reacting masses

Stage 1

1. Find the mass of MgCl2 produced when 426 g of Cl2 are reacted.

Cl2 + Mg --> MgCl2

2. Find the mass of BeCl2 produced when 1.8 g of Be are reacted.

Be + Cl2 --> BeCl2

3. Find the mass of KOH used when 1071 g of KBr are produced.

KOH + HBr --> KBr + H2O

4. Find the mass of Sr used when 1590 g of SrCl2 are produced.

Cl2 + Sr --> SrCl2

5. Find the mass of CuS produced when 192 g of S are reacted.

Cu + S --> CuS

Stage 2

6. Find the mass of H2 produced when 49 g of Li are reacted.

2H2O + 2Li --> 2LiOH + H2

7. Find the mass of CH4 produced when 4 g of H2 are reacted.

2H2 + C --> CH4

8. Find the mass of S8 used when 532 g of CS2 are produced.

4C + S8 --> 4CS2

9. Find the mass of CH4 used when 162 g of H2O are produced.

CH4 + 2O2 --> CO2 + 2H2O

10. Find the mass of CCl4 produced when 497 g of Cl2 are reacted.

C + 2Cl2 --> CCl4

Stage 3

11. Find the mass of H2 used when 51 g of NH3 are produced.

3H2 + N2 --> 2NH3

12. Find the mass of H2O produced when 3.2 g of O2 are reacted.

3O2 + 4NH3 --> 6H2O + 2N2

13. Find the mass of CO2 produced when 1136 g of C10H22 are reacted.

31O2 + 2C10H22 --> 22H2O + 20CO2

14. Find the mass of BH3 produced when 20 g of H2 are reacted.

2B + 3H2 --> 2BH3
