3. if an ion contains 10 electrons,
12 protons, and 13 neutrons, what is
the ion's charge?

The charge of the ion is 2+.

Explanation:

The amount of neutrons is extra information. You just need to compare the amount of electrons to the amount of protons for the ion's charge.

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
