What is H├óÔÇÜÔÇÜO commonly known as?
Correct answer
C
Rationale
H├óÔÇÜÔÇÜO is the chemical formula for water, consisting of two hydrogen atoms bonded to one oxygen atom. This molecule is fundamental to life, acting as a solvent, temperature regulator, and participant in biological reactions. Water covers about 71% of Earth├óÔé¼Ôäós surface and exists in three states├óÔé¼ÔÇØsolid (ice), liquid, and gas (vapor). It is vital for metabolism, transportation of nutrients, and maintaining ecological balance. The strong hydrogen bonds between its molecules give water unique properties like high surface tension and specific heat capacity.
