I think you forgot to give the options along with the question. I am answering the question based on my research and knowledge. "You should remove heat energy because air is a gas and particles need to slow to become a liquid" is the way you can make water for drinking in the desert. I hope it helped you.

The hall reaction of an oxidation-reduction reaction shows that iron gains electrons. What does this electron gain mean for iron

AnnZ [28]

Answer: Iron gains electrons mean It is reduced

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

$Zn\rightarrow Zn^{2+}+2e^-$

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

$Fe^{2+}+2e^-\rightarrow Fe$

Thus iron gains electrons mean It is reduced

a sample of substance x that has a mass of 326.0 g releases 4325.8 cal when it freezes at its freezing point. if substance x has

ira [324]

1) Calculate the number of mols,n, of the substance

n = mass/ molar mass = 326.0 g / 58.45 g / mol = 5.577 moles

2) Calculate the molar heat of fusion as the total heat released by the sample divided by the number of moles

hf = heat released / n = 4325.8 cal / 5.577 moles = 775. 59 cal /mol
