Explain how many liters of S03 (g) are produced at 25C and 1.0atm from the combustion of 1.0kg of coal which is 1.0%S by weight? Suppose all the sulfur in the coal ends up as S03.
Calculate the following for an oil (MW=169g/mol) that distills during steam distillation at a boiling temperature of 98°C at 1atm of pressure. A) The mass of the oil that codistills with each one gram of water at 98°C
Given the information below calculate ?H°rxn for: C2H4(g) + 6F2(g) => 2CF4 + 4HF(g). H2(g) + F2(g) => 2HF(g) ?H° = -537 kJ C(s) + 2F2(g) => CF4(g) ?°H = -680 kJ 2C(s) + 2H2(g) => C2H4(g)
