Diborane, \(\text{B}_{2}\text{H}_{6}\), was once considered for use as a rocket fuel. The combustion
reaction for diborane is:
\[\text{B}_{2}\text{H}_{6}\text{(g)} + 3\text{O}_{2}\text{(g)} \rightarrow 2\text{HBO}_{2}\text{(g)} +
2\text{H}_{2}\text{O (l)}\]
If we react \(\text{2,37}\) \(\text{g}\) of diborane, how many grams of water would we expect to
produce?

Sodium azide is a commonly used compound in airbags. When triggered, it has the following reaction:
\[2\text{NaN}_{3}\text{(s)} \rightarrow 2\text{Na (s)} + 3\text{N}_{2}\text{(g)}\]
If \(\text{23,4}\) \(\text{g}\) of sodium azide is used, how many moles of nitrogen gas would we expect
to produce? What volume would this nitrogen gas occupy at STP?

Photosynthesis is a chemical reaction that is vital to the existence of life on Earth. During
photosynthesis, plants and bacteria convert carbon dioxide gas, liquid water, and light into glucose
(\(\text{C}_{6}\text{H}_{12}\text{O}_{6}\)) and oxygen gas.

If \(\text{3}\) \(\text{mol}\) of carbon dioxide are used up in the photosynthesis reaction, what
mass of glucose will be produced?
