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 CO2(g)
2. How many grams of magnesium iodide do I make if I consumed 8.21E24 molecules of elementary iodine by the following chemical equation?
1 Mg(s) + 1 I2(s) --> 1 MgI2(s)
3. How many L of ammonia (NH3) @STP do I have if I consumed 127L 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?
