An anion is an ion that has gained electrons and because of this it has an overall electrical charge that is negative due to the excess of electrons, which is greater than the atomic number or number of protons for the atom.

A. O2- is the anion.

Degger [83]

Answer:

12

Explanation:

pOH = -log(1.0 x 10^-2) = 2

pH = 14 - pOH

pH = 14 - 2 = 12

Place the following compounds in order of increasing magnitude of lattice energy. Ga2o3 rbi mgs k2s.
valentinak56 [21]

Increasing order of magnitude of lattice energy is rbi <K2s< Mgs < Ga2O3.

Lattice energy is the energy change upon the formation of one mole of a crystalline ionic compound from its constituent ions. It depends upon the charges of the ion and the distance between the center of the ion when they are packed in the form crystal. Basically lattice energy is determined by the charge of the atom and the atomic radii of the atoms.

In Ga2O3, Ga has 3+ and O has 2- ions .so it has the lattice energy of 6.this is calculated by multiplying q1 and q2 .this attracts strongly.

In rbI , R has +1 and i has -1.so it ha lattice energy of -1.ther is no strong attraction nor lattice energy.

In Mgs, Mg has +2 and s has -2 .this is not as strong as Ga2o3 but stronger than rbi.

In K2S, k has =1  and s has 2-.this is stronger than rbi.

How many moles of H2O are in 12.3L?
11111nata11111 [884]
You take 12.3L + avogadro's number (6.022409x10^23
=7.407233x10 ^24 mols 
I know it's a long number but you can have long numbers. I'm pretty sure this right.
