okay im getting closer(: so would nicket(II) oxide be NiO2 and dichlrine pentoxide be Cl2O5

Chemistry
okay im sure i can get one right soon. now if it has a polyatomic in the equation like Tin(IV) nitrate would it be SnNO3? and if it produces iron(III)nitrate would it be Fe(NO3)3

Chemistry
sorry but i want to make sure im doing this right. for lithium+gold(III chloride-->lithium chloride+gold would it be Li+AuCl2-->LiCl2+Au?
