Question - Enter the compound formula, including state, of the missing substance ( Y ) in the balanced equation below. Do not give the coefficient. Polyatomic ions only need parentheses when there is more than one of the given ion in the molecular formula.
K2SO4(aq) + Pb(NO3)2(aq) ---> Y + 2KNO3(aq)
I don't know how to reach these answers thus please show the steps, thank you!
