Ответ учителя по предмету Химия
CaO + SO2 = CaS03
Cal2 + H2SO3 = CaSO3! + 2HI
Cal2 + K2SO3 = CaSO3! + 2KI
CaBr2+ H2SO3 = CaSO3! + 2HBr CaBr2 + K2SO3 = CaSO3! + 2KB. CaCl2 + H2SO3 = CaSO3l + 2HCI

Unfortunately, most power plants are not very efficient: in a typical old plant running on coal, only about a third of the energy locked inside the fuel is converted to electricity and the rest is wasted. Newer designs, such as combined cycle power stations (which we’ll explore in a minute) may be up to 50 percent efficient. As the chart here shows, even more electricity is squandered on the journey from the power plant to your home. Adding all the losses together, only about a fifth of the energy in the fuel is available as useful energy in your home.
