Hi! You use the sign based on whatever your given ΔH is. If you aren't sure about that, you can use q and see if the temperature increased or decreased to see if the reaction is endothermic or exothermic. Endothermic reactions absorb heat, and the temperature increases so q is positive and ΔH is positive.
