Answer:

-4

Explanation:

It went from a 7 to a 2 and 7-2 is 4, so it changed by 4 and it went down by 4.

Assuming that there is missing information in this question I’m just going to go ahead and say that it’s lower.

HNO3 (nitric acid) is a very strong acid which should be found on the lower end of the pH scale. While water, on the other hand, is neutral and found at a pH of 7.

So if you add one drop of a strong acid into a neutral solution of 100ml let’s say, one can assume that the pH of that solution is now very low and probably found between 1-3 on a pH scale.

Reminder:

-Acids are found between 1-6 on the pH scale. The lower the number the stronger the acid

-Bases are found between 8-14 on the pH scale. The higher the number the stronger the base

which atomic particle determines the chemical behavior of an atom the nucleus, neutron, electron, proton or none of these
dusya [7]
The chemical behavior of an atoms is determine by the formation or destruction of chemical bonds. The chemical bonds are the result of the interaction of the electrons of the atoms. Chemical properties of the atoms are given by how attached are the shell electrons attached to the nucleus and how they interact with other atoms. Chemical changes are the result of exchange valence electrons of the atoms. So, <span>the answer is the atomic particle that determines the chemical behavior of an atom is the electron, because it is the particle that is active in chemical bonding.</span>

Atoms are indivisible spheres-Dalton model

John Dalton was the first to propose a theory to describe matter. As per Dalton's model, all matter is composed of atoms which resemble tiny 'ball-like' structures that are indivisible.
