please help w/ both

You mix 136ml of 0.155MLiOH with 136ml of 0.41MHF in a coffee-cup calorimeter, and the T of the solution rises from 21.0C to 26C (what does that mean T increasing?). What is the enthalpy of reaction/mole of LiF ( H in kJ/mol? ?)? Assume density of the solutions are all 1.00g/ml, and the cof the solutions are 4.2J/gK. Use the correct sign (+ vs 1. Enter to 1 decimal place with the corfect sign (+ or ). Select the correct term. 2CO2(g)+566kJ/mol2CO(g)+O2(g) endothermic exothermic
