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>
Answer:
<h3>The answer is 1.5 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question we have
We have the final answer as
<h3>1.5 g/mL</h3>
Hope this helps you
I think its A because if you do proseccs of illumination... B and C dont make sence at all...and between A and D, A is the best answer
A IS YOUR ANSWER
hope this helps!
Answer:
Following are the responses to the given points:
Explanation:
Form the above-given question, it indicates that the bromate ion green ionizes in water to form a green-blue solution, therefore the before adding the HCL it indicator was in anionic from hence it is written as In^{-} therefore the HCL is mixed which the anion is protonated to give HIN
