What are the formal charges of both chlorines and iodine in icl2?
Answers
Answer:
Explanation:
Formal charge of ICl₂⁻
Formal charge = group no - ( no of non bonding electrons +no of bonds)
In I there are 7 electrons in outermost orbit . If we add one more electrons due to - ve charge on the ion , it becomes eight . This centrally placed iodine forms two single bond with two chlorine atoms on either side.
Each of chlorine atoms also contains 7 valance electrons like iodine.
So formal charge of chlorine
= group no - ( no of non bonding electrons +no of bonds)
= 7 - ( 6 + 1 )
= 0
So formal charge of iodine
= group no - ( no of non bonding electrons +no of bonds)
= 7 - ( 5 + 2 )
=0
Formal charge of ICl₂⁺
In this case , central iodine will have only 6 valence electrons due to absence one electron.
So formal charge of chlorine in ICl₂⁺
= group no - ( no of non bonding electrons +no of bonds)
= 7 - ( 6 + 1 )
= 0
formal charge of iodine in in ICl₂⁺
7 - ( 4 + 2)
= 1

Considering the Charles' Law, the volume increases from 400 mL to 410.85 mL as the temperature increases from 22.0 °C to 30.0°C.
Charles' Law
Charles' Law consists of the relationship that exists between the volume and the temperature of a certain amount of ideal gas, which is maintained at a constant pressure.
For a given sum of gas, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. This is, the volume is directly proportional to the temperature of the gas:
In summary, Charles' law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:
Studying two different states, an initial state 1 and a final state 2, it is fulfilled:
Volume change
In this case, you know:
- V1= 400 mL
- T1= 22 C= 295 K (being 0 C= 273 K)
- V2= ?
- T2= 30 C= 303 K
Replacing in the Charles's law:
Solving:
410.85 mL= V2
Finally, the volume increases from 400 mL to 410.85 mL as the temperature increases from 22.0 °C to 30.0°C.
Learn more about Charles's law:
T₁ = 22.0ºC + 273 = 295 K
V₂ = ?
T₂ = 30.0ºC + 273 = 303 K
V₁ / T₁ = V₂ / T₂
400.0 / 295 = V₂ / 303
295 x V₂ = 400.0 x 303
295 V₂ = 121200
V₂ = 121200 / 295
V₂ = 410.84 mL
hope this helps!

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Electron has -1 charge while proton has +1 charge. Neutron is neutral.
Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
