Question

How much heat energy is absorbed when 7 moles of water boils according to the reaction below

Answer 1

+284.9 kJ

Step-by-step explanation:

So in this equation you get the heat absorption which is +40.7 kJ.

We can see that H2O (l) to H2O (g) is a 1:1 ratio, meaning forever 1 mole of H2O (l), 1 mole of H2O (g) is produced.

All we have to do now is find how much heat absorption there in 7 moles of water so all we have to do is:

7(40.7 kJ) = 284.9 kJ
