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
BA(OH)2 (Barium hydroxide)
Barium hydroxide is a chemical compound with the chemical formula Ba(OH)₂ₓ. The monohydrate, known as baryta or baryta-water, is one of the principal compounds of barium.
Answer:
C. One mole of water was produced from this reaction.
Explanation:
- From the balanced equation:
<em>2H₂ + O₂ → 2H₂O,</em>
It is clear that 2 mol of H₂ react with 1 mol of O₂ to produce 2 mol of H₂O.
- So, if one mole of hydrogen was used in this reaction:
1/2 mol of O₂ was used in the reaction, and
1 mol of water was produced from this reaction.
- So, the correct statement is:
<em>C. One mole of water was produced from this reaction.
</em>
Plants are the producers — they use the sun's energy to convert water and carbon dioxide into plant material via photosynthesis. ... A producer is a living thing that makes its own food from sunlight, air, and soil. Green plants are producers who make food in their leaves.
