Determine the oxidation number of chlorine in CI2 with the steps
1 answer:
Answer: The oxidation number of chlorine in is zero
Explanation:
Oxidation number or oxidation state : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Rules for Oxidation Numbers are :
1. The oxidation number of a free element is always zero.
2. The oxidation number of a monatomic ion equals the charge of the ion.
3. The oxidation number of oxygen (O) in compounds is usually -2.
4. The oxidation number of a Group 17 element in a binary compound is -1.
5. The oxidation number of Hydrogen (H) is +1, but it is -1 in when combined with less electronegative elements.
6. The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
7. The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.
As exists as a free molecule, its oxidation state is zero.

Answer: a. solution
Explanation:
A solution is a mixture which contains two or more than two types of components and they can be separated by physical means as well.Example: salt water
Molecule of an element is defined as the aggregate of atoms of similar elements. Example: . Molecule of a compound is the aggregate of atoms of different elements in a fixed ratio by mass. Example:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example:
A pure substance is a substance which contains definite composition of only one type of component. Hence, it cannot be separated by physical means. Example: Helium, water
