Use the balanced chemical equation to determine what the limiting reactant is and how much excess reactant is leftover. Assume each molecule represents one mole of the substance.
[b]2H[sub]2[/sub]([i]g[/i]) + O[sub]2[/sub](g) → 2H[sub]2[/sub]O([i]g[/i])[/b]

Question 2
How many grams of zinc oxide would you need to produce 50.0 g of zinc chloride?
[b]ZnO([i]s[/i]) + 2HCl([i]aq[/i]) → ZnCl[sub]2[/sub]([i]s[/i]) + H[sub]2[/sub]O([i]l[/i])[/b]
[b]ZnO([i]s[/i]) + 2HCl([i]aq[/i]) → ZnCl[sub]2[/sub]([i]s[/i]) + H[sub]2[/sub]O([i]l[/i])[/b]

Question 3
The balanced chemical equation below shows a ratio of two H[sub]2[/sub]O for every one O[sub]2[/sub].
[b]2H[sub]2[/sub](g) + O[sub]2[/sub](g) → 2H[sub]2[/sub]O(g)[/b]
This ration represents the ratio between the ________.
[b]2H[sub]2[/sub](g) + O[sub]2[/sub](g) → 2H[sub]2[/sub]O(g)[/b]

Question 4
How many moles of oxygen would you need to produce 4 moles of aluminum oxide?
4Al([i]s[/i]) + 3O[sub]2[/sub]([i]g[/i]) → 2Al[sub]2[/sub]O[sub]3[/sub]([i]s[/i])
4Al([i]s[/i]) + 3O[sub]2[/sub]([i]g[/i]) → 2Al[sub]2[/sub]O[sub]3[/sub]([i]s[/i])
