The decomposition of hydrogen peroxide to form water and oxygen gas releases 196.6 kJ per mole of hydrogen peroxide. This reaction occurs when hydrogen peroxide is placed on a cut to sterilize it. How much heat is released when 5.70 mol H2O2 decompose

Respuesta :

Answer:

1120.62 kJ

Explanation:

In order to find how much heat is released for 7.70 mol, we have to compare it with the heat released from one mole.

So from the question, we have;

196.6 kJ = 1 mol

x = 5.70

x = 5.70 * 196.6 / 1

x = 1120.62 kJ
