Question

Complete and balance the following molecular equation.
HBr(aq)+Ca(OH)2(aq)→

Express your answer as a balanced chemical equation. Identify all of the phases in your answer.

and write the ionic equation for it

Answer 1

The specified reaction is an acid-base reaction, by which the products, salt and water, are formed. Here, the provided acid is HBr, the provided base is Ca(OH)2, hence on the product si de, water and the salt, Ca(Br), , are formed. This can be written as Balance Br atom in the reaction. 2HBr(aq) + Ca (OH)2 (aq) → H2O(1) + CaB5 (aq) Cais also balanced, hence balance H atom. Thus, 2HBr(aq) + Ca (OH), (aq) → 2H20(1) + CaB5 (aq) This results in the bal ance of each other atom. Hence, the balanced equati on is, 2HBr(a)+Ca(H) a2H0()+CaBr(ag) The ionic form, in general, is written for aqeous phases (aq). Hence, theionic equati on is, 2H'(aq)+2Br(aa)+Ca2* (aq)+20H (aH(i)+Ca2*(aq)+2Br(aa)
