Hydrogen and oxygen gas combine explosively to produce water. Write a balanced chemical equation for this process. If 10 mol of hydrogen reacted with oxygen, what volume of liquid water could be produced?
2H2 + O2 ==> 2H2O
10 mol hydrogen, if it has all the oxygen needed, will produce, according to the coefficients in the balanced equation, 10 moles H2O.
A mole of H2O has a mass of 18 g; therefore, it should produce 180 g H2O and if water has a density of 1.00 g/mL, that will be 180 mL H2O.
