In lab performed experiments where we combine a certain amount of HCL with NAOH. For instance, 25ml of 1M HCL we then measured temp then we added 75 ml of 1M NaOH then we measure the temp. Explain what are the moles of H+, moles of OH-, and moles of H2O. Explain what is the heat released during reaction. Also what is the enthalpy of neutralization? Does doubling the volumes of acid and base double the amount of heat? Does doubling the concentration of acid base double the amount of heat released?
