<K <C 1 only 2 only 3 only D.2 and 3 E all of them QUESTION 5 When 3.66 g of CaO (molar mass: 56.08 g/mol) is added to 50.0 g of water at 25.0 °C in a calorimeter, the temperature of the water increases to 32.3 °C. Assuming the specific heat of the solution is 4.184 J/g-°C and that the calorimeter itself absorbs no heat, calculate AH in kJ/mol for the reaction below. Enter the answer to 3 significant figures. CaO(s)+H₂O(1)→ Ca(OH)2(aq) itions represent an emission of a photon (select all that apply)? nswers
