What does H-O-H represent? a. ionic bonding of water b. a molecule of water c. an atom of water d. a mixture including water<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is b. a molecule of water<\/strong>.<\/p>\n\n\n\n The notation “H-O-H” represents the structure of a water molecule<\/strong>, where two hydrogen atoms (H) are bonded to one oxygen atom (O). This arrangement is also commonly represented as H\u2082O. The bonds between hydrogen and oxygen in water are covalent bonds<\/strong>, meaning that the atoms share electrons to achieve stability. More specifically, these bonds are polar covalent<\/strong>, which means the electrons are not shared equally.<\/p>\n\n\n\n In a water molecule, the oxygen atom is more electronegative than the hydrogen atoms. Electronegativity is the tendency of an atom to attract electrons in a bond. As a result, the oxygen atom pulls the shared electrons closer to itself, making it partially negatively charged (denoted \u03b4-) and leaving the hydrogen atoms partially positively charged (denoted \u03b4+). This polarity gives water its unique properties.<\/p>\n\n\n\n Because of the bent shape of the H-O-H molecule (with a bond angle of approximately 104.5\u00b0), water is a polar molecule<\/strong>. This polarity is responsible for water’s ability to form hydrogen bonds with other water molecules or substances, leading to its high cohesion, surface tension, and ability to dissolve many polar substances. This makes water a “universal solvent,” playing a crucial role in biological systems, chemical reactions, and the environment.<\/p>\n\n\n\n What does H-O-H represent? a. ionic bonding of water b. a molecule of water c. an atom of water d. a mixture including water The Correct Answer and Explanation is : The correct answer is b. a molecule of water.
