Water’s heat of vaporization is 2,257 joules/gram. How much energy is released when 11.2 grams of water vapor condenses into liq
1 answer:
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

The spectator ions in the reaction between aqueous and aqueous HCl would be
and
ions.
Spectator ions are anions or cations that exist both as reactants and as products in a reaction. Their forms remain unchanged both in the reactants and in the products.
Aqueous and aqueous HCl react according to the following equation:
Before the reaction, and
existed in the reactants as
and HCl respectively. After the reaction,
and
exist as
in the product.
Thus, the spectator ions in this case are and
ions because their forms did not change after the reaction.
