7 is neutral on the pH scale
Answer: Option (a) is the correct answer.
Explanation:
A miscible solution is defined as the one in which two or more than two components are soluble with each other.
So, when hexane is added to heptane then both of them will mix with each other and hence they are miscible. This mixing will lead to formation of more number of ions into the solution as a result, more will be the disorder present in the solution.
As entropy is the degree of randomness present.
Hence, we can conclude that a solution of hexane and heptane will lead to an increase in entropy.
Answer:
I am pretty sure the correct answer is a reproductive system
Center of the solar system
No. of moles = given mass/atomic mass
= 452/40
= 11.3.
Thus, there are 11.3 moles
