The cooling curve above shows how the temperature of a sample varies with time as the sample goes through phase changes. the sample starts as a gas, and heat is removed at a constant rate. at which time does the sample contain the most liquid?
Option (c) is the correct answer.Explanation:Since it is given that there are 10 electrons in atom A, therefore its octet is complete and hence it is unreactive in nature. Whereas...Read More

HA ==> H+ + A- So %-ionization = [H+]/[HA] x 100% Ka = [H+][A-]/[HA] = 3.2 x 10^-7 Let [H+] = x. Then [A-] = x and [HA] = 0.10 - x. But x is so small that we can neglect it and...Read More
