Q #1: A represents atomic mass and 2 represents an atomic number, which of the following describes an atom after a proton is emitted?

A. A-1,2-1

B. A-1,2+1

C. A,2-1

D. A+1,2-1

Answer Explanation

This is because when a proton is emitted from an atom, the atomic mass decreases by one unit, and the atomic number decreases by one unit. The atomic mass is the sum of protons and neutrons in the nucleus, and the atomic number is the number of protons in the nucleus. Therefore, if a proton is lost, both numbers decrease by one.
Q #2: Which of the following is correct regarding the pH scale?

A. A substance with a pH of 3 is two times more alkaline than a substance with a pH of 4

B. A substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4

C. A substance with a pH of 3 is two times more acidic than a substance with a pH of 4

D. A substance with pH of 3 is 10 times more alkaline than a substance with a pH of 4

Answer Explanation

The pH scale is logarithmic, indicating that each whole number change on the pH scale represents a tenfold change in acidity or alkalinity. Therefore, a substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4.
