Is oil energy renewable? A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource. Fossil fuels such as oil, natural gas, and coal are examples of nonrenewable resources. Renewable resources are the opposite: Their supply replenishes naturally or can be sustained. […]

Which has the highest first ionization energy? helium Which of the following is highest ionization energy? Neon Which has highest second ionization energy? Hellium has the highest ionization energy. Which has higher ionization energy Na+ or Mg+? In the second case (When an electron has been removed from both) Na+ becomes stable while Mg+ does […]

Does smoking change sperm DNA? How does smoking affect sperm? Men who smoke have decreased sperm concentration, decreased motility (how sperm swim), fewer normally shaped sperm, and increased sperm DNA damage. Do cigarettes alter your DNA?
