Complete and balance the chemical equations for the reactions of group 1 metals. Be sure to include the correct phases of the products.

Question

equation: ___ Li(s)+O2(g)⟶ ___

equation: ___. Na(s) + O2(g) -> ___

equation ___. Cs(s)+O2(g)->. ___

equation: 2Cs(s)+2NH3(l)

Note that the (am)(am) phase denotes the solvation of the ions by liquid ammonia.

⟶2Cs+(am)+2NH−2(am) + ___

Answer 1

2Li(s) + O₂(g) ==> Li₂O(s)

2Na(s) + O₂(g) ==> Na₂O(s)

2Cs(s) + O₂(g) ==> Cs₂O(s)

2Cs(s) + 2NH₃(l) ==> 2Cs⁺(am) + 2NH₂^-(am) + H₂(g)
