please help, will mean a lot. thanks in advance.

1) Which of the following values will be used to calculate the number of moles of water produced in a neutralization reaction involving NaOH with excess HCl, when the concentration of NaOH is unknown? (Select all that apply)

(a) volume of acid/base (b) standard enthalpy of neutralization (c) molarity of acid/base (d) kJ of heat released by the reaction

2. In a neutralization reaction involving a strong acid and a strong base the heat of reaction:

(a) results from union of a cation/anion to form salt (b) -55.9kJ/mol water produced (c) more or less than -55.9kJ/mol of water produced - depends on reactants nature (d) dependent on volume of water produced (e) endothermic

3. View the neutralization between the following two solutions: 100.0 mL 1.2382 M hydrochloric acid, HCl & 150.0 mL 0.7205 M sodium hydroxide, NaOH. How many moles of water are produced by this neutralization? Give your answer with the correct significant digits." ___ moles H₂O = ? "

4. 10.91 g of solid NaOH is added to a calorimeter containing 250 mL of deionized water. Temperature change is recorded and the following values are determined: T_initial = 20.50 C T_final = 30.72 C

Assume the specific heat of this solution is the same as water, 4.184 J/deg*g and no heat was lost to the calorimeter. Molar mass of NaOH = 39.997 g/mol

"___ kJ/mol of NaOH = ? "

5. There was an experiment carried out to determine the heat of reaction, q, for the neutralization of a weak electrolyte. The experiment results determined that q = -67.5 kJ per mole of water produced, so what does this result indicate?

(a) there is an error since not possible result (b) ionization/dissociation step is weak electrolyte; exothermic (c) ionization/dissociation step is weak electrolyte; endothermic
