Carbon tetrachloride was widely used for many years as a solvent until its harmful properties became well established. Carbon tetrachloride may be prepared by the reaction of natural gas (methane, CH₄) and elemental chlorine gas in the presence of ultraviolet light. Write the unbalanced chemical equation for this reaction.(HCl(g) is a product of this reaction. Include states-of-matter under SATP conditions in your answer.)

CH4(g) + Cl2(g) = CCl4(g) + HCl(g)

Explanation:

Carbon tetrachloride is in the form of a colorless gas. It is not flammable and is not soluble in water (poor solubility). It is a compound used as a fire extinguisher and in the manufacture of refrigerants, but is currently discontinued for its toxicity. Exposure causes damage to the liver, kidneys and central nervous system. These effects can happen by breathing it or through skin contact. In the reaction the states of matter of each of the reagents and products are observed

a)the ionic radius of phosphorus

Explanation:

phosphorus=2.8.6

for phosphorus to become stable(2.8.8) it gains two electrons thus the ionic radious increases bcz of the gained electrons
