Question

A gas is confined to a cylinder under constant atmospheric pressure, as illustrated in the following figure. When the gas undergoes a particular chemical reaction, it absorbs 829J of heat from its surroundings and has 0.69kJ of P−V work done on it by its surroundings. What is the value of ΔH for this process?

Answer 1

So I think 829 is ΔH and for ΔE I'm not sure

Answer 2

\[\Delta H = 829\] \[\Delta E\] is what i'm trying to figure out

Answer 3

hhheeeelllpppp meee
