Question

K2+1CO32–(aq) + Sr2+(NO3–)2(aq) → SrCO3(s) + 2K+NO3–(aq). What is the net ionic equation for the reaction?
a) 2K+(aq) + 2NO3–(aq)
b) 2K+1(aq) + CO32–(aq) + Sr2+(aq) + 2(NO3–)(aq) → SrCO3(s) + 2K+(aq) + 2NO3–(aq)
c) This is a combustion reaction so there is no net ionic equation
d) CO32–(aq) + Sr2+(aq) → SrCO3(s)

Answer 1

b is the total ionic equation. Cancel the items on the left that appear on the right to obtain d which is the net ionic equation.
