I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.

Are any of these equations redox reactions? if so what are their reducing and oxidizing agents?
MaRussiya [10]

Yes, Fe(s)+CuSO4→FeSO4(aq)+Cu(s) is a redox reaction. The reducing agent is Fe(s), while the oxidizing agent is CuSO4.

<h3>Oxidation-reduction reaction (redox)</h3>

Oxidation-reduction reaction is the type of reaction in which electrons are transferred from one element to another. A compound or an element either gains are looses an electron in redox reactions.

Fe(s)+CuSO4→FeSO4(aq)+Cu(s)

From the equation above, Fe(s) is the reducing agent because it gives away 2 electrons and undergoes oxidation reaction.

From the equation above, CuSO4 is an oxidizing agent because it gives oxygen to Fe(s) and undergoes a reduction reaction.

Therefore, the reducing agent is Fe(s), while the oxidizing agent is CuSO4.

What is the difference between chemical and electrical gradient? When defined, they both sound very similar; is there a way to d
soldi70 [24.7K]

chemical gradient is defined as the a gradient appearance by the dissimilarity in concentration of a certain type of solute in an universal solvent take examples like salt in water.

<span> electrical gradient is defined as the  disparity between the electrical potential of a given solute in an universal solvent. fundamentally, if the chemical that establishes the chemical gradient is electrically charged. Then the diversity in the charge over the barrier will produce an electrical gradient</span>
