Question
PLEASE JUST EXPLAIN B NO NEED TO DO A
H3BO3 (aq) → HBO2 (aq) + H2O (l) ΔH1 = - 0.02 kJ/mol
H2B4O7 (aq) + H2O (l) → 4HBO2 (aq) ΔH2 = - 11.3 kJ/mol
H2B4O7 (aq) → 2B2O3 (s) + H2O (l) ΔH3 = 17.5 kJ/mol
a)Find the ΔH for this overall reaction: 2H3BO3 (aq) → B2O3 (s) + 3H2O (l)
b)If 545 J of heat are absorbed or released from the reaction of 330. mL of H3BO3solution, what was the molarity of the solution?
