Which of the following is a balanced chemical equation?

mgf2 + li2co3 ⟶ mgco3 + lif
ch4 + 2o2 ⟶ co2 + h
2al + 6hcl ⟶ 3h2 + alcl3
p4 + 3o2 ⟶ 2p2o3

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
