How many grams of H₂ are produced with the reaction of 36 grams of water?

2 Na + 2 H20 -> 2 NaOH + h2

2g

Explanation:

The balanced equation for the reaction is given below:

2Na + 2H2O —> 2NaOH + H2

Next, we'll determine the mass of the water (H2O) that reacted and the mass of H2 produced from the balanced equation.

This is illustrated below:

Molar Mass of H2O = (2x1) + 16 = 18g/mol

Mass of H2O from the balanced equation = 2 x 18 = 36g

Molar Mass of H2 = 2x1 = 2g/mol

Therefore, from the balanced equation above, 36g of H2O reacted to produce 2g of H2.

From the illustration above, we can see that 36g of water will produce 2g of H2.
