${\text{H2+ O}}_{\text{2}}\to {\text{ H}}_{\text{2}}\text{O}$

a. Balance the equation.

b. How many moles of ${\text{H}}_{\text{2}}\text{O}$ can be produced if you have 2.72 mol of ${\text{O}}_{\text{2}}$ and an unlimited amount of ${\text{H}}_{\text{2}}$?

c. How many moles of ${\text{H}}_{\text{2}}$ would be necessary to produce 10.0 g of water?

d. How many grams of water would be formed by the complete reaction of 2.5 g of ${\text{H}}_{\text{2}}$?
