A chemical reaction is run in which 132 joules of work is done by the system amd the internal energy changes by 469 joules. Calculate the amount of heat transferred.

u=q+w I was going to do 469 = q + 132 but I think this is wrong.

    I believe the internal energy of a system decreases when work is done by the system so dE = q+w
    469 = q +(-132)
    q = 469 + 132 = ? Check my thinking.
