Question

Как решать степени окисления?пж

Answer 1

Для простых веществ степень окисления равна 0

Оксиген всегда имеет степень окисления -2.

Гидрогена всегда имеет -1

Степень окисления в большинстве случаев совпадает с валентностью.

Answer 2

How to Solve Oxidation States?

To solve oxidation states, you need to follow a set of rules and guidelines. Here is a step-by-step process to determine the oxidation state of an element in a compound:

1. Assign oxidation states to atoms in their elemental form: In their elemental form, atoms have an oxidation state of zero. For example, oxygen (O2) has an oxidation state of zero.

2. Assign oxidation states to monatomic ions: Monatomic ions have oxidation states equal to their charge. For example, the oxidation state of sodium ion (Na+) is +1, and the oxidation state of chloride ion (Cl-) is -1.

3. Assign oxidation states to hydrogen and oxygen: Hydrogen usually has
