C2H5OH is ethanol or ethyl alcohol and on combustion releases carbon dioxide and water. The easiest way to figure out the number of moles of products generated is by writing a balanced chemical equation for the reaction.
The combustion of ethanol (C2H5OH) can be represented by the following balanced chemical equation:
`C_2H_5OH + 3O_2 -> 2CO_2 + 3H_2O`
We can check if the equation is balanced by comparing the number of atoms of each element on both sides of the equation. For example, there are 2 atoms of carbon on both sides of the equation. Similarly, there are 7 atoms of oxygen on both sides.
From this equation, we can see that 1 mole of ethanol reacts with 3 moles of oxygen and generates 2 moles of carbon dioxide and 3 moles of water.
Thus, 1 mole of ethanol on complete combustion yields 3 moles of water.
Hope this helps.
