A solution's pH will be a number between 0 and 14. A solution with a pH of 7 is classified as neutral. If the pH is lower than 7, the solution is acidic. When pH is higher than 7, the solution is basic. These numbers describe the concentration of hydrogen ions in the solution and increase on a negative logarithmic scale. For example, If Solution A has a pH of 3 and Solution B has a pH of 1, then Solution B has 100 times as many hydrogen ions than A and is therefore 100 times more acidic.
Answer: Electrons
Explanation: Electrons are the subatomic particles that are located in the orbitals or shells instead of the nucleus of an atom. Electrons orbit around the core of an atom where the protons and neutrons are located.
Answer:
CH2
Explanation:
The empirical formula gives the lowest whole number ratio of the elements. In this case, both subscripts can be divided by 20, hence CH2.
