Why can three atoms of magnesium have different masses?

Chemistry

Answer: the atoms of those isotopes have the same atomic number (number of protons), making them belong to the same ele- ment, but they have different mass numbers (total number of protons and neutrons) giving them differ- ent atomic masses.

Answer:

Three atoms of magnesium can have different masses because each of the three atoms has a different number of neurons.

I hope this helped :)

How are solubility and temperature generally related in a system consisting of a solid solute and a liquid solvent?
Nesterboy [21]

Solubility and temperatures are directly related. The higher the temperature of the solvent, the higher the solubility of the solute in the solvent.

Dissolving a solute in a solvent is an endothermic process hence providing heat favors the  process. Higher temperatures cause the molecules of the solvent to have high kinetic energy hence bombard each other and with that of the solute with high frequency. This then ensures fast diffusion of the solute particles in the solvent.

What happen in the dark reaction
Firdavs [7]
Answer

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.
