Water                   . a. is a good solute; b. facilitates chemical reactions; c. serves as an enzyme; d. makes strong covalent bonds with other molecules; e. consists of two oxygen and one hydrogen atoms

Verified step by step guidance

1. Identify the properties of water and its molecular composition. Water is a molecule composed of two hydrogen atoms and one oxygen atom, represented by the chemical formula H2O.
2. Evaluate each statement: a) Water is not a solute but a solvent, which means it is the substance in which other materials dissolve. b) Water does facilitate chemical reactions by acting as a medium where reactants can meet and react. c) Water does not serve as an enzyme; enzymes are proteins that catalyze biochemical reactions. d) Water forms polar covalent bonds within its own molecule (between the oxygen and hydrogen atoms) and can form hydrogen bonds with other molecules, but it does not typically form strong covalent bonds with other molecules. e) The correct molecular composition of water is two hydrogen atoms and one oxygen atom (H2O), not two oxygen and one hydrogen.
3. Determine which statement(s) correctly describe the properties or composition of water based on the evaluation in step 2.
4. Select the correct answer(s) from the options provided based on the analysis. In this case, the correct statement about water is that it facilitates chemical reactions.
5. Conclude that the correct answer to the question is option 'b' - facilitates chemical reactions.

Key Concepts

Properties of Water

Water is known for its unique properties, including being a polar molecule, which allows it to dissolve many substances, making it an excellent solvent. This property is crucial for biological processes, as it facilitates the transport of nutrients and waste in organisms.

Role of Water in Chemical Reactions

Water plays a vital role in biochemical reactions, often acting as a medium where reactions occur. It participates in hydrolysis and condensation reactions, which are essential for breaking down and synthesizing biomolecules, respectively.

Molecular Structure of Water

The molecular structure of water consists of two hydrogen atoms covalently bonded to one oxygen atom, forming a bent shape. This arrangement leads to hydrogen bonding between water molecules, contributing to its high specific heat, surface tension, and solvent capabilities.
