Explanation:
when you perform electrolysis on water, you are turning water into hydrogen and oxygen gas, that's where the bubbles come from. ... You turned water into water vapor. The main difference is that electrolysis is a chemical change and boiling is a physical change.
When water is boiled, it undergoes a physical change, not a chemical change. The molecules of water don't break apart into hydrogen and oxygen.
One of the best electrolytes for water electrolysis is sulphuric acid (H2SO4). When it ionises in water, it breaks down, depending on its concentration, to either H+ and HSO4- or 2 H+ and SO4- -.
Answer:EPA
Under SDWA, EPA sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards.

Explanation:
- Carbon dioxide
- Uric acid
- Urea
- ammonia, etc.
Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).
Nitrogen fixation is performed naturally by certain types of anaerobic bacteria. Legumes such as clover contain symbiotic bacteria of this type within nodules in their root systems, producing nitrogen compounds that help to fertilize the soil. See George Washington Carver.
Nitrogen can also be artificially fixed for use as fertilizer or in other industrial processes. The most popular method is by the Haber process. Artificial fertilizer production has achieved such scale that it is now the largest source of fixed nitrogen in the Earth's ecosystem.

yes he did ,
In 1873, Joseph Lister isolated the first bacterial pure culture which he called Bacterium lactis. This lactic acid bacterium is now called Lactococcus lactis and is used for fermenting milk to produce hundreds of different dairy products.
