1. How many grams of elementary copper did I make if I also made 56.7L CO₂@STP using following chemical equation.

2 CuO_(s) + 1 C_(s) --> 2 Cu_(s) + 1 CO_2(g)

2. How many grams of magnesium iodide do I make if I consumed 921g of elementary iodine by the following chemical equation?

1 Mg_(s) + 1 I_2(s) --> 1 MgI_2(s)

3. How many L of ammonia (NH₃) @STP do I have if I consumed 25.4g of hydrogen gas?

1 N_2(g) + 3 H_2(g) --> 2 NH_3(g)

4. How many grams of Iron (III) oxide do I need to make 35.4 grams of aluminum oxide?

1 Fe₂O_3(s) + 2 Al_(s) --> 2 Fe_(s) + 1 Al₂O_3(s)

Answer:
1. 324g Cu
2. g MgI₂
3. L NH₃@ STP
4. 55.5g Fe₂O₃
