Question

Which of the following represents the correct neutralization reaction of hydrobromic acid and calcium hydroxide?

HBr + Ca(OH) 2 -> CaBr2 + H2O


HBr + CaOH -> CaH + BrO


2 HBr + Ca(OH) 2 -> CaBr2 + 2 H2O


HBr + Ca(OH) 2 -> CaH2 + Br2O

Answer 1

i would look up what "acid-base neutralization" means in the book. what are the key reactants that neutralize each other? two of the choices are not neutralization reactions and they can be eliminated.

of the remaining choices, i would do a atom inventory. one of them is unbalanced. so the other one is correct choice.

Answer 2

C. 2 HBr + Ca(OH) 2 CaBr2 + 2 H2O
