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.
Ba(NO3)2(aq) + Y ----> BaC2O4(s) + 2LiNO3(aq)
