There is a fresh, clean water shortage in the world. You, as a chemical engineer, can make some. Let's see if you can make 2000 L of water for less than $ 1000.
First, tell me why there is a shortage of fresh water (what is your hypothesis)? Second, what can we do to fix that?
Third, you remember that you can make water form H2 and O2?
$H_2 + O_2 \rightarrow H_2O$
Balance it. Use stoichiometry coefficients.

Hypothesis, solution
$CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O$
2, 2 (I used 2 in front of the oxygen and 2 in front of the water)
