Answer:
ΔH is negative and ΔS is negative.
Explanation:
Endothermic reaction -
The type of reaction in which energy is absorbed in the form of heat is known as endothermic reaction .
The reaction mixture usually get cooled after the reaction .( temperature decreases ) .
The sign of ΔH of an Endothermic reaction is positive .
<u>For the of process of freezing the liquid ethanol , energy in the form of heat is released and hence , exothermic reaction ΔH is negative .</u>
<u>In the process of freezing , liquid is converted to solid , i.e. , the randomness reduces , and hence , entropy also decreases , hence , ΔS is negative .</u>
The least reactive metal is lead, since it reacted with none of the salt solutions.
Your answer→ <em>The lighter side absorbs less of the incident light, reflecting some of the energy. Darker materials also emit radiation more readily than light-colored materials, so they cool faster.</em>

I Don't Know.
Explanation: I'm Sorry, But I'm Not Good At This Subject. Atleast I'm Being Honest.
One way a machine can make work easier is by being faster and more efficient. Most machines can do human work quicker and more successfully.
