I think answer should be carbon dioxide
Answer: AIBN is good radical initiator
Explanation:
A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.
Answer:

Explanation:
Hello!
In this case, since the ionization of ammonia, which is a weak base, is written as:

We can see that the ammonium ion is the conjugate acid whereas the hydroxide ions the conjugate base; that is why we use the Henderson-Hasselbach equation to compute the pH, given the pKb of ammonia 4.75:
![pH=pKb+log(\frac{[conj\ acid]}{[base]} )](https://tex.z-dn.net/?f=pH%3DpKb%2Blog%28%5Cfrac%7B%5Bconj%5C%20acid%5D%7D%7B%5Bbase%5D%7D%20%29)
In such a way, for the given moles of ammonia, base, and those of ammonium chloride, conjugate acid form, we obtain:

I believe the correct answer from the choices listed above is the third option. The kinetic theory explains that heat is due to the motion of molecules. Temperature is the measurement used to measure heat and is directly proportional to the average kinetic energy of the molecules.
a strong acid fully dissociates in water to form H+ ions in water while a weak acid only partially dissociates to form H+ ions in water
