Here are the answers that would best complete the given statement above. The air you breathe is made of 21% oxygen and 78% nitrogen. The oxygen in air is the SOLUTE and the nitrogen is the SOLVENT. In a given mixture, the reagent having the highest percentage of amount is always the solvent and the one or ones having the lower percentages are the solutes. Hope this answer helps.
Electrolysis and heat can separate a compound into its elements.

Answer:
H2 + I2 --> 2HI
Explanation:
The two reactants are diatomic molecules because they contain two atoms of the same element. Therefore, they would need to have a subscript of "2" next to their symbols.
When balancing an equation, you want the same amount and type of atoms on both sides. By adding a coefficient of "2" in front of the product, two H's and two I's are now on both sides.
Moles of Ammonia produced : 4 moles
<h3>Further explanation</h3>
Given
6 mol of H₂
Required
moles of Ammonia
Solution
Reaction
N₂ + 3H₂ → 2NH₃
In chemical equations, the reaction coefficient shows the mole ratio of the reacting compound (reactants and products)
From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol NH₃ :
= 2/3 x moles H₂
= 2/3 x 6
= 4 moles
