Answer 1

Water is composed of two hydrogen atoms bonded to one oxygen atom, forming H₂O. It is essential for life, involved in numerous biological processes. Water purification methods include boiling, filtration, chlorination, and using UV light. Boiling kills pathogens, while filtration removes impurities like dirt and chemicals. Chlorination adds disinfectants to kill germs, and UV light destroys harmful microorganisms without chemicals.
