Final answer:
Methane and elemental chlorine are involved in the production of carbon tetrachloride, represented by the balanced chemical equation CH4 + 4 Cl2 ⇒ CCl4 + 4 HCl.
Step-by-step explanation:
The compounds involved in the production of carbon tetrachloride are methane (CH4) and elemental chlorine (Cl2). The balanced chemical equation for producing carbon tetrachloride is:
CH4(g) + 4 Cl2(g) ⇒ CCl4(l) + 4 HCl(g)
This reaction can also produce a variety of chlorinated methane compounds depending on the conditions, including chloromethane, dichloromethane, and chloroform. Carbon tetrachloride is specifically produced after multiple substitutions of hydrogen atoms by chlorine atoms in methane.
