Experiment 5Heats of Reaction – Hess’s Law Pre LabTotal Points: 3Student’s Name: Samantha Springer Lab Section: 161In the space below, combine two of the previous equations (page 59) algebraically to obtain the third equation. Indicate the number the number of each reaction. (HINT: you may need to reverse one or more equations.)Reaction NumberEquations1 (reversed) Na^+ (aq) + OH^- (aq) -> NaOH (s) 2NaOH (s) + H^+ (aq) +Cl^- (aq) -> Na^+ (aq) +Cl^- (aq) + H2O (l) Algebraic SumNa^+ (aq) + OH^- (aq) +H^+ (aq) + Cl^- (aq) -> Na^+ (aq) + Cl^- (aq) +H2O (l) Or simplified OH^- (aq) + H^+ (aq) -> H2O (l)
