Every element in the compound has its own formal charge. The formula is:
Formal charge = Valence electrons - Nonbonding electrons - Bonding electrons/2
Let the Lewis structure of the compound aid you.
1. For CO:
Formal charge of C = 4 - 2 - 6/2 = -1
Formal charge of O = 6 - 2 - 6/2 = +1
2. For CO₂:
Formal charge of C = 4 - 0 - 8/2 = 0
Formal charge of each O = 6 - 4 - 4/2 = 0
3. For CO₃²⁻:
Formal charge of C: 4 - 0 - 8/2 = 0
Formal charge of two O's single-bonded to C = 6 - 6 - 2/2 = -1
Formal charge of the O double-bonded to C = 6 - 4 - 4/2 = 0
Potassium iodide will act as the catalyst to decompose hydrogen peroxide into water and oxygen. A catalyst is a substance that participates in a chemical reaction and influences its speed without undergoing permanent change.<span>

What is the option just give that thing also
The sun is a luminous object while the moon is a non luminous object it only reflect the light from the sun... It takes 8.5 minutes for the light coming form the sun to reach the earth, it takes 1.3light seconds for the moon to reflect the light coming from the sun to the earth... The sun is a star while the moon is a satellite both the sun and the moon are round in shape... The sun has an outer temperature of about 6000°C while there is no breeze in the moon...
