Thank you! I really Appreciate it!
I will show you how to do one and then you can have a go at the others. First decide if the mixture will give you a reaction, a precipitate. If there is no reaction there is neither a molecular equation or a net ionic equation.
Start with the molecular formula
Na2CrO4(aq) + Sr(NO3)2(aq) -> NaNO3(aq) + SrCrO4(s)
balance the equation
Na2CrO4(aq) + Sr(NO3)2(aq) -> 2NaNO3(aq) + SrCrO4(s)
write in all the ions
2Na+(aq) + CrO4^2-(aq) + Sr^2(aq)+2NO3-(aq)->
2Na2+(aq)+ 2NO3-(aq) + SrCrO4(s)
now you delete ions that appear on each side, so you end up with
CrO4^2-(aq) + Sr^2(aq)->
SrCrO4(s)
which is the net ionic equation.
Mgcl+k2SO4
To find the molecular equation and net ionic equation for each reaction, you need to balance the chemical equation first. The molecular equation represents the overall reaction with formulas of the reactants and products, while the net ionic equation shows only the species that participate in the reaction.
