3. How many grams of ammonia (NH3) do I have if I consumed 42.1g of hydrogen gas?


Answer the following questions showing all work. Where needed, write the balanced chemical reaction.

1. How many grams of elementary copper did I make if I also made 92.5g CO2 using following chemical equation.

2 CuO(s) + 1 C(s) --> 2 Cu(s) + 1 CO2(g)

2. How many grams of magnesium iodide do I make if I consumed 371g of elementary iodine by the following chemical equation?

1 Mg(s) + 1 I2(s) --> 1 MgI2(s)

3. How many grams of ammonia (NH3) do I have if I consumed 42.1g of hydrogen gas?

1 N2(g) + 3 H2(g) --> 2 NH3(g)

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

1 Fe2O3(s) + 2 Al(s) --> 2 Fe(s) + 1 Al2O3(s)

Answers:

1) 269g Cu
2) 406g Mg1I2
3) 196g NH3
4) 55.5g Fe2O3
