Explanation:
When we add chlorine to a substance or compound then this process is known as chlorination.
For example, a process of chlorination is as follows.
Initiation : 
where, Cl* is a free radical.
Propagation:
Termination:
Thus, we can conclude that out of the given options 
is not formed through a termination reaction in the chlorination of methane.
As, overall order of reaction is 2 indicates the rate of reaction is only depending on concentration of A and its rate of reaction can be shown as:
R = K [A]^2
So, by increasing the concentration of A, the rate of reaction increases.
Here we have to choose the atom which has same number of neutrons as 14N
The atom which has same number of neutrons as 14N among the given atoms is (D) 13C
We know, in an atom the number of electrons (atomic number) is equivalent to the number of protons. For nitrogen (N), the number of electron is 7. Thus the number of protons present in the nucleus is also 7 to make the atom uncharged.
The mass number of the atom is the number of the neutrons + number of the protons. In 14N there are 7 protons and 7 neutrons.
Thus among the given atoms the atom which has 7 neutrons will have the same number of neutrons.
A) Now in 16O the atomic number is 8 and mass number is 16. Thus the number of protons and neutrons are each 8 units.
B) In 15N, the atomic number is 7 but mass number is 15, thus number of protons and neutrons are 7 and 8 respectively.
C) In 14P the atomic number is 15 but mass number is 14, so number of protons and neutrons are 15 and -1 (not exist) respectively.
D) In 13C the atomic number is 6 and mass number is 13. So the number of protons are 6 and number of neutrons are 7.
Thus the correct answer will be D) 13C.
The volume of 1.0 g of nitrogen in a balloon is increased. It causes: the mass of the gas to decrease the density of the gas to increase and the pressure of the gas to decrease the temperature of the gas decrease.
<h3>What is volume?</h3>
How much space an object or substance takes up.
If you increase the temperature of the gas in the balloon, the pressure will initially increase. The balloon will expand until the pressure inside drops back down and is equal to the pressure outside.
If you increase the atmospheric pressure, the balloon will compress until the pressure inside equals the new pressure outside.
If you remove gas from the balloon, the pressure will drop, causing the balloon to compress until the pressure is again equal to the pressure outside.
if you place the balloon underwater, it will be under greater pressure, causing the balloon to compress until the inside pressure equals the new outside pressure.
