What does ion exchange remove?
What does ion exchange remove? The ion exchange process is widely used for the removal of hardness (as in softening), heavy metals (as in waste treatment), radionuclides (as from power plants) and municipal water feeds (removal of nitrates, arsenic, perchlorate, hexavalent-chrome and others). How is chloride removed from water? Chloride can be removed from drinking […]
What triggered big bang?
What triggered big bang? Over billions of years, stars “cook” hydrogen and helium atoms in their hot cores to make heavier elements like carbon and oxygen. Large stars explode over time, blasting these elements into space. This matter then condenses into the stars, planets, and satellites that make up solar systems like our own. Is […]

What are the sources of thermal power?
What are the sources of thermal power? Fuels such as heavy oil, LNG (liquefied natural gas) and coal are burned inside a boiler to generate steam at high temperature and high pressure. This steam is used to rotate the impeller of the steam turbine. This drives the power generators connected to the turbine that generate […]
What happens if the electrons are not replaced in chlorophyll?
What happens if the electrons are not replaced in chlorophyll? If these electrons are not replaced, the chlorophyll will be unable to absorb additional light and the light-dependent reactions will stop, as will the production of ATP. To replace the lost electron, molecules of water are split in the first photosystem. What light does chlorophyll […]
