It turns chemical into electricity
It's b. hydrogen bonds between water molecules
it is water because it is dissolving the sodium chloride
The values of enthalpy change, entropy change and temperature all determine the spontenity of a reaction.
<h3>What is a sponteanous reaction?</h3>
A sponteanous reaction is one which has the change in free energy as negative. We know that ΔG = ΔH - TΔS. The spontenity of a reaction depends on;
i. enthalpy change
ii. entropy change
iii. temperature
Since the values in the qestion are not given, the question is incomplete and we can not obtain a numerical value in order to decide the sponteanity of the reaction.

The solubility of NaCl in water will not be affected by an increase in pressure.
We know that the density of NaCl(s) in 2.165 g/cm³ at 25 °C and we want to know how will its solubility in water be affected when the pressure is increased.
<h3>What is solubility?</h3>
Solubility is the maximum mass of a solute that can be dissolved in 100 grams of solvent at a determined temperature.
The solubility of a solid, such as NaCl, in a liquid, is mainly affected by the temperature. However, since solids are not compressible, an increase in pressure will not affect its solubility.
On the other hand, the solubility of gases in water will increase with an increase in pressure, as stated by Henry's law.
The solubility of NaCl in water will not be affected by an increase in pressure.
