Assume that Silver Nitrate and Calcium Bromide are the starting substances (reactants) in the reaction.

Question

a. Write a balanced chemical reaction between

Silver Nitrate and Calcium Bromide. Be sure to include physical states.

b. State the names of the products that are produced from this reaction.

c. Write complete ionic and net ionic reactions for the balanced equation in part (a).

d. What type of reaction(s) is/are being represented by the chemical reaction written in part (a)?



e. Based on your answers to parts (a) - (d), determine if a solid precipitate is formed in this

reaction. If yes, state its chemical formula.

Answer 1

a) 2AgNO₃(aq) + CaBr₂(aq) ==> 2AgBr(s) + Ca(NO₃)₂(aq)

b) Silver bromide and calcium nitrate are the products

c) 2Ag⁺(aq) + 2NO₃^-(aq) + Ca²⁺(aq) + 2Br^-(aq) => 2AgBr(s) + Ca²⁺(aq) + 2NO₃^-(aq) .. complete ionic

2Ag⁺(aq) + 2Br^-(aq) ==> 2AgBr(s) .. net ionic

d) double replacement, precipitation

e) yes, a solid precipitate is formed and it is AgBr (silver bromide)
