A nuclear reaction changes the number of protons and or neutrons in an atom.
<h3>What do nuclear reactions change in the atom?</h3>
A nuclear reaction is a type of reaction that results in the change of the nucleus of an atom. We know that a nucleus of an atom is made up of protons and neutrons.
So we can conclude that a nuclear reaction changes the number of protons and or neutrons in an atom.

Answer:
2.13atm
Explanation:
The following information were obtained from the question:
P1 (initial pressure) = 2atm
T1 (initial temperature) = 27°C = 27 + 273 = 300K
T2 (final temperature) = 47°C = 47 + 273 = 320K
P2 (final pressure) =?
Using the equation P1/T1 = P2/T2, the final pressure within the tyre can be obtained as illustrated below:
P1/T1 = P2/T2
2/300 = P2/320
Cross multiply to express in linear form
300 x P2 = 2 x 320
Divide both side by 300
P2 = (2 x 320)/300
P2 = 2.13atm
Therefore, the pressure within the tyre at 47°C is 2.13atm
Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
