Pentane reacts with oxygen in a combustion reaction to produce carbon dioxide and water. C5H12 + O2 -> CO2 + H2O If you have 5.00 moles of pentane, how many moles of water will be produced?

Respuesta :

Ajiduah1

Answer: 30 moles of H2O

Explanation:

First we write the balanced equation for the combustion reaction of 1 mol of Pentane.

C5H12 + 8O2 ------>  5CO2 +  6H2O

From the balanced equation of the reaction;

1 mole of Pentane (C5H12) produces  6moles of water.

∴ 5 moles of Pentane would have an equation like this when you multipy all the coefficients by 5

 5 C5H12  + 40 O2 -------> 25 CO2  + 30 H2O, which means; 5 moles of pentane would produce 30 moles of water.
