Question

Using the equation below, calculate how many grams of water (H2O) you have if you start with 12 grams of

Answer 1

Answer:

12g

Explanation:

The following equation is given in this question:

2H2 + O2 → 2H2O

According to this balanced chemical equation, 2 moles of hydrogen gas is used to produce 2 moles of water molecule.

Hence, if 12 grams of hydrogen is used, 12 × 2/2 = 24/2

= 12 grams of H2O will be produced.
