Question

Can you explain the combustion of `1*mol` of ethyl alcohol in terms of mass and energy?

Answer 1

Well, first we require the complete reaction......

Explanation:

`C_2H_5OH(l) + 3O_2(g)rarr2CO_2(g) + 3H_2O +Delta`

Both mass and charge are balanced, as is ABSOLUTELY REQUIRED.... There are 7 oxygen atom reactants, i.e. `112*g`, and `112*g` oxygen products....

And because we make STRONG `C=O` and `H-O` bonds, the reaction is exothermic, and releases energy.
