Heat of vaporization is the heat required to vaporize unit mass of a substance at it's boiling point. The heat of vaporization or condensation of water is 2257 J/g.
It means that 1 g of water involves 2257 J energy during condensation or vaporization at its boiling point (100 C)
Given mass of water vapor that is condensing = 11.2 g
Calculating the heat released when 11.2 g of water vapor condenses in to liquid water at 100
:
Rounding the final answer 25,278 J to three significant figures we get, 25,300 J
Therefore the correct answer is E. 25,300 J
Explanation:
Below is an attachment containing the solution.
Answer:
option C.there is an accumulation of carbon dioxide.
Explanation:
In order for a solute to dissolve in a solvent,
the attractive forces between solute particles and the solvent particles must
be stronger than the attractive forces between solute-solute and
solvent-solvent particles. This is important so that the solute will remain in
solution.
Answer:
A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
