Not sure if this is right but this is what I think
Thermal energy added: Particles move faster, Kinetic energy increases, Temperature increases
Thermal Energy removed: Particles move slower, Kinetic energy decreases, Temperature decreases
Answer:
B (Final mass of the metal)
Explanation:
The independent variable in this experiment is the amount of acid the scientist pours on the metal, and the only variable in the list dependent on the amount of acid poured on the metal is the final mass of the metal. Therefore, the final mass of the metal is the dependent variable in the experiment.

Hi
B. "Radioactive isotopes last for less time" I believe.
Hope this helped ^^;
Answer:
Its atomic mass is 14 ( = 6 protons + 8 neutrons). In chemistry, the number of protons in an atom is more important than the number of neutrons. Scientists call the number of protons the "atomic number"
