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

Petroleum products include fuel oils for heating and electricity generation.
It is a feedstocks for making the chemicals and plastics.
We use petroleum to produce electricity.
Answer:
2486 mmHg
Explanation:
Gay-Lussac's Law states the pressure varies directly with temperature when volume remains constant:
P₁/T₁ = P₂/T₂
Where P₁ and T₁ are initial pressure and temperature and P₂ and T₂ are final pressure and temperatue.
The problem says initial pressure is 721 mmHg, initial temperature is 25°C and final temperature is 755°C. The question is final pressure.
°C must be converted to absolute temperature (K), thus:
25°C + 273,15 = 298,15 K
755°C + 273,15 = 1028,15 K
Thus, pressure P₂ is:
(T₂·P₁) / T₁ = P₂
1028,15K · 721mmHg / 298,15 K = 2486 mmHg
