C.) both secrete toxins and have thorns (It simply depends on what kind of plant it is)
Oxidation is when the overall charge (or oxidation number) increases. The only way to increase an oxidation number is to lose an electron, thereby making the negative charges less. The correct answer is C.
So it can break down the egg’s exterior and enter
D:
When electrons are gained, the charge of the atom decreases.
When you are given an atom with a charge, the oxidation of that atom is the charge. So by going from a Cr^3+ (Oxidation Number = 3) to a Cr^2+ (Oxidation Number = 2), the Oxidation Number thus decreases.
the answer is 15.
4+4+4+1 =13 then u add the 2 outside the bracket which will give u 15
