Answer:
Explanation:
We will need a balanced chemical equation with masses, moles, and molar masses.
1. Gather all the information in one place:
Mᵣ: 18.02
2Na + H₂O ⟶ 2NaOH + H₂
m/g: 72.0
2. Moles of H₂O
3. Moles of Na
The molar ratio is 2 mol Na/1 mol H₂O.

Answer:
C.
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust.
So I set up the problem as follows:
Solve for X, and you should get 52g Solution
