Under each sentence, write the correct formula for each substance, then balance the reaction, REMEMBER THE HEAVENLY SEVENI Hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and lodine in the gas phase are all diatomic
(all but Brand I are gasses at or around room temperatures) -- meaning their formula in an equation will be H, N, O,
F, Ch, Br, and I
8) Zinc and copper I sulfate yield zinc sulfate and copper metal
9) Iron plus sodium bromide make iron III bromide and sodium
10)
Calcium oxide and aluminum make aluminum oxide and calcium
