Answer:
The mass of reactants and products for the reaction is this:
- 92 g Na, 32 g Oâ‚‚, 124 g Naâ‚‚O
which is not a choice from the list.
Explanation:
4 moles of Na reacts with 1 mol of oxygen to produce 2 moles of sodium oxide.
Na = 23 g/m
4 moles are (4 . 23) = 92 g
Oâ‚‚ = 32 g/m
It's a diatomic molecule (each O is 16 g/m)
Naâ‚‚O = 62 g/m
2 mol of sodium oxide will be (2 .62) = 124 grams
The mass of reactants and products for the reaction is this:
- 92 g Na, 32 g Oâ‚‚, 124 g Naâ‚‚O
which is not a choice from the list.
