Answer: C. Although nuclear power can provide cheaper electricity while producing less pollution, the risk of nuclear waste and the potential for a disaster should be considered.
Explanation:
The nuclear power plants uses the radiation energy to cause fission of heavy atoms. The energy is produced in the form of thermal energy. The nuclear power plants do not produce, carbon dioxide and other pollutants in the environment, thus these do not cause pollution in the environment. The radioactive waste are highly mutagenic in nature this causes deadly mutations in the living beings. Thus a risk is associated with the generation of energy in the nuclear power plant.
Because when you live in the middle of one, you have less rocking and less moving of the earth under you. If you were to live near a plate, the plate would move up, down, or side to side and make your house or any building move up and down.
Answer:-A. It is less than 890 kJ/mol because the amount of energy required to break bonds is less than the amount of energy released in forming bonds.
Explanation: Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
for the reaction comes out to be negative.
In the formation of new bonds more energy is released than is required to break the existing bonds, heat is released.
In the formation of bonds less energy is released than is required to break the existing bonds, heat is absorbed.
