Question 8.49

In the question it states that the reaction produces heat but then delta H is negative. And I'm not sure if this is right, but I thought that heat would be negative since delta h is negative. BUT since the reaction produces heat that also leads me to think that heat would be positive. Basically I'm confused on whether the q(heat) is negative or positive.

Yes, delta H would be negative because it is an exothermic reaction where the system gives off heat.

When a reaction produces heat (is exothermic), heat leaves the system. ΔH is negative because this represents heat leaving the system as it is produced.
