N$_2$ + 3 H$_2$ $\longrightarrow$ 2 NH$_3$

If 5.0 grams of N$_2$ react with excess H$_2$ how many grams of NH$_3$ will the reaction yield?

P$_4$ + 5 O$_2$ $\longrightarrow$ 2 P$_2$O$_5$

Starting with 8.00 g P$_4$ and 8.00 g of O$_2$, how many grams of P$_2$O$_5$ will the reaction yield?

CuCl$_2$ + Zn $\longrightarrow$ ZnCl$_2$ + Cu

20.0 mL of 1.50 M CuCl$_2$ reacts with 3.00 Zn. How many grams of ZnCl$_2$ does the reaction yield?

3 F$_2$ + S $\longrightarrow$ SF$_6$

Sulfur hexafluoride, a very good indicator, is prepared by the reaction of sulfur with elemental fluorine. What mass of SF$_6$ can be produced from the reaction of 150 g of S with 650 g of F$_2$ ?

MM of F$_2$ = 38.00 g/mol

MM of SF$_6$ = 146.06 g/mol
