Use the following information to find Hf of ethanol [CH3CH2OH(l)]. CH3CH2OH(l) + 3 O2(g) 2 CO2(g) + 3 H2O(g)

Hcomb = -1406.8
Hf of CO2(g) = -393.5 kJ/mol
Hf of H2O(g) = -241.8 kJ/mol

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
