Answer:
P(H₂) = 807.2 torr
Explanation:
According to the Dalton law, the pressure of mixture of a gas is sum of the partial pressure of its mixing component gases.
P(total) = P1 + P2 + P3 +....
In given problem,
Total pressure is = 794 torr
Partial pressure of water = 13.2 torr
Partial pressure of hydrogen = ?
Solution:
P(total) = P(H₂O) + P(H₂)
P(H₂) = P(total) - P(H₂O)
P(H₂) = 794 torr - 13.2 torr
P(H₂) = 807.2 torr
Answer is: seventy eight (78) atoms in this reaction.
In this balanced chemical reaction there are twelve carbon atoms (from two molecules of C₆H₁₄), twenty eight atoms of hydrogen (from two molecules of C₆H₁₄) and thirty eight atoms of oxygen (from nineteen molecules of oxygen):
12C + 28H + 38O = 78 atoms total.

Answer:
The volume of the gas decreases also in a 21% based on the Avogadro's law
Explanation:
Based on Avogadro's law, the volume of a gas is directely proportional to the amount of moles of gas when temperature and pressure remain constants.
The formula is:
V1 / n1 = V2 / n2
<em>Where V is volume and n are moles in 1, initial state and 2, final state of the gas.</em>
<em />
At beginning, V1 = 100%, n1 = 100%,
As the chemist removes 21% of the gas, 79% of moles remain = n2.
Replacing:
100% / 100% = V2 / 79%
V2 = 79%, that means:
<h3>The volume of the gas decreases also in a 21% based on the Avogadro's law</h3>
