Question

predict whether a reaction occurs, and if so, write on a separate piece of paper the balanced total and net ionic equations (in the field provided you only need to input the sum of the coefficients of the net ionic equation, so enter a whole number, e.g. 0, 1, 2, 3, etc): sodium hydroxide (aq) cadmium(ii) nitrate (aq)

Answer 1

A double replacement reaction occurs between sodium hydroxide and cadmium(II) nitrate to form the products cadmium hydroxide and sodium nitrate. The balanced net ionic equation is 2OH- (aq) + Cd2+ (aq) -> Cd(OH)2 (s)

Step-by-step explanation:

A double replacement reaction occurs between sodium hydroxide (NaOH) and cadmium(II) nitrate (Cd(NO3)2) to form the products cadmium hydroxide (Cd(OH)2) and sodium nitrate (NaNO3). The balanced total ionic equation is:

2Na+(aq) + 2OH-(aq) + Cd2+(aq) + 2(NO3)-(aq) → Cd(OH)2(s) + 2Na+(aq) + 2NO3-(aq)

The balanced net ionic equation, obtained by removing the spectator ions (Na+ and NO3-), is:

2OH-(aq) + Cd2+(aq) → Cd(OH)2(s)
