A substance with a pH of 10 is how much more basic than a substance with a pH of 2?

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent

The sum of the oxidation numbers in a neutral compound is always

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released
