Enter the complete ionic equation to show the reaction of aqueous lead(ii) nitrate with aqueous potassium sulfate to form solid lead(ii) sulfate and aqueous potassium nitrate. express your answer as a chemical equation. identify all of the phases in your answer.

Pb(NO3)2(aq) + K2SO4(aq) --> PbSO4(s) + 2KNO3(aq) 

Total ionic equation: 

Pb 2+ (aq) + 2NO3- (aq) + 2K+ (aq) + SO4 2- (aq) > PbSO4 + 2K+ (aq) + 2NO3- (aq) 

For the net ionic equation cancel out species found on both sides to get: 

Pb 2+ (aq) + SO4 2- (aq) > PbSO4(s) 

Note aqueous species dissolve and are separated into their ions but solid ones do not and simply precipitate out of solution.

The answer is a) carbon-12

Maybe you should get some from your teacher and learn more so you can get your grades up and maybe study a bit more
