A small mistake in 2nd question ⁉️ Answer is grinders.... Sorry for that mistake CFCs (Chlorofluorocarbons) are a group of chemical compounds that were once widely used in various products due to their non-flammable and non-toxic properties. However, they were later found to be responsible for the depletion of the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation. Answer: The correct answer is B) Grinders. CFCs were not used in grinders. They were primarily used in: * A) Fire extinguishers: Some fire extinguishers, especially those designed for electrical fires, used CFCs as a propellant. * C) Aerosol sprays: Many aerosol sprays, such as hairspray and deodorant, used CFCs as propellants. * D) Refrigerators: Early refrigerators and air conditioners used CFCs as refrigerants. Due to their harmful impact on the ozone layer, the use of CFCs has been phased out in most applications.
The Chemical name of gypsum is Calcium Sulphate Dihydrate. CaSO 4 ·2H 2 O The Chemical name of Plaster of Paris is Calcium Sulphate hemihydrate. CaSO 4 ·½H 2 O
Sir, 2 ND question answer chudandi again A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine used in refrigerants and in fire extinguishers. CFC reaches ozone layer and each chlorine molecule present in CFC break down one lack molecule of ozone.
