Particles are farther apart in gases so substance X is water vapor

Explanation:

The best statement that fits the two described substances is that particles are farther apart in gases so substance X is water vapor. For a give mass of substance, gases occupies more volume.

Gases do not have specific volumes, occupy space randomly and fills whichever container they are found in.

Liquids on the other hand like solids have specific volume because their particles are very close together.

Particles of gases are random and their molecules are far apart.

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] 6H₂ + O₂ → 3H₂O

[Given] 18 mol H₂

[Solve] mol H₂O

<u>Step 2: Identify Conversions</u>

[RxN] 6 mol H₂ → 3 mol H₂O

<u>Step 3: Stoich</u>

[DA] Set up conversion: $\displaystyle 18 \ mol \ H_2(\frac{3 \ mol \ H_2O}{6 \ mol \ H_2})$
[DA] Simplify: $\displaystyle 18 \ mol \ H_2(\frac{1 \ mol \ H_2O}{2 \ mol \ H_2})$
[DA] Divide [Cancel out units]: $\displaystyle 9 \ mol \ H_2O$
