Fe + S --> FeS

2. Find the mass of MnO2 produced when 160 g of O2 are reacted.

Mn + O2 --> MnO2

3. Find the mass of H2O produced when 14 g of KOH are reacted.

HBr + KOH --> H2O + KBr

4. Find the mass of Cl2 used when 119.25 g of SrCl2 are produced.

Sr + Cl2 --> SrCl2

5. Find the mass of MgCl2 produced when 35.5 g of Cl2 are reacted.

Mg + Cl2 --> MgCl2

Stage 2

6. Find the mass of H2 used when 224 g of C2H4 are produced.

2C + 2H2 --> C2H4

7. Find the mass of CuO produced when 160 g of O2 are reacted.

O2 + 2Cu --> 2CuO

8. Find the mass of H2 produced when 14 g of Li are reacted.

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

9. Find the mass of Cl2 used when 1625 g of ICl are produced.

Cl2 + I2 --> 2ICl

10. Find the mass of Cl2 used when 38.5 g of CCl4 are produced.
