Chemistry
Nacl(s)+ HCl---->H20 +NaCl(aq) delta H(amouint of energy aborbed by the solution is 4263.6J) Is it okay to say that H2 represents the heat evolved to neutralize 2g of NaOH with an acid

Chemistry
NaOH(aq) + HCl(aq)----> H20 + Nacl(aq).. solve for the amoont of energy aborbed by the solution. (50ml of 1.0M HCl is 23deg; 50ml of 1.0M NaOH is at 25deg; mixed solutuion= 31deg pls tell me the steps to take inorder to solve the question. Thanks in advance.
