Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.
However, the use of solar panels is environment friendly. Solar power is renewable at absolutely no cost to supply energy infinitely. Also, it is very low maintenance. Once installed, the solar power system can last twenty to thirty years.
Similarly wind (turbines) and water (hydroelectric power plants) are an endless source of energy without negatively affecting the environment.
The answer is B. have a good day! :)
Answer:
Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.
Explanation:
Answer:
the molecular mass of hydrogen sulphide, which contains two atoms of hydrogen and one atom of sulphur is = 2 — 1 + 1 — 32 = 34 a.m.u.
