I have more than one problem I need help with. Any help is extremely appreciated. 1. The problem statement, all variables and given/known data Problem 1. The heat of neutralization of HCl by NaOH is delta H of reaction = -56.2 kj/mol. How much heat is released when 125mL of 1.750 M HCl is mixed with 195mL of 0.667 M NaOH? 2. Relevant equations q= ms delta T 3. The attempt at a solution I have no idea how to get this problem from volume and molarity to something like grams or moles that I can actually work with. 1. The problem statement, all variables and given/known data Problem 2. The combustion of one mole of benzene, C6H6, in oxygen liberates 3268 kJ of heat. The products of the reaction are carbon dioxide and water. How much heat is given off when 183 g of oxygen are reacted with excess benzene? 2. Relevant equations q = ms delta T 3. The attempt at a solution I also have no idea how to even begin this problem. I don't even quite understand what they are asking for, let alone answering it.
