What is the molecular formula for water _______ ?
Show answer Hide answer
Answer: B. H2O
Explanation
A water molecule is composed of two hydrogen atoms bonded to one oxygen atom. This specific atomic arrangement is represented universally by the chemical formula H2O in science. Covalent bonds hold the hydrogen and oxygen atoms together within each stable molecular structure. Water is a polar molecule with a bent molecular geometry creating distinct partial electrical charges. Chemical formulas express the exact ratio of constituent elements present in a pure chemical compound. Hydrogen bonding between water molecules accounts for its unique high boiling point and cohesion.
Biological systems require water as a universal solvent for essential metabolic biochemical reactions. Environmental scientists monitor water quality parameters to ensure safe drinking supplies for human populations. Industrial manufacturing processes utilize water extensively as a cooling agent and chemical solvent. NaAlO2 represents sodium aluminate, which is a specialized chemical compound used in water treatment. Al2O3 is the chemical formula for aluminum oxide, commonly known as alumina in mineralogy. CaSiO3 denotes calcium silicate, a ceramic material found in various construction and mineral products.
