It is possible to dehydrate neutral and basic gases, amines, low-boiling alcohols, and ethers using calcium oxide, a basic drying agent. its chemical formula is CaO.
CaO cannot be substituted with sulfuric acid. Because the salt ammonium sulfate is created when sulphuric acid and ammonia combine, this is the case. Calcium oxide is a solid that is odorless, white, gray-white, and appears as hard lumps. powerful skin, eye, and mucous membrane irritant. used in fertilizers and pesticides. The group of calcium oxides with a 1:1 ratio of calcium to oxygen includes calcium oxide. It functions as fertilizer.

Answer:
Partial pressure of CO2 = 16 atm
Explanation:
Total number of moles of gases = 4+1 = 5 moles
Mole fraction of CO2 = 4/5
Partial pressure of CO2 = mole fraction of CO2 × total pressure
Partial pressure of CO2 = (4/5) × 20
Partial pressure of CO2 = 16 atm
Answer:
1. Fe + H2SO4 = FeSO4 + H2
iron + sulfuric acid = duretter + hydrogen
2. Mg + 2 HNO3 = Mg(NO3)2 + H2
Magnesium + nitric acid = magnesium nitrate +hydrogen
3. Zn + 2 HCl = ZnCl2 + H2
Zinc + hydrogen chloride= zinc chloride+ hydrogen
