Question

question 1 explain how a water strider can float on the surface of water without sinking. question 2 why is water considered the universal solvent? question 3 whats the difference between an ionic bond and a covalent bond?

Explanation:

Question 1: Water has surface tension due to hydrogen - bonding between water molecules. Water striders have hydrophobic legs and their weight is distributed over a large area, allowing them to float on the surface without breaking the surface tension.
Question 2: Water is considered the universal solvent because it is a polar molecule. Its polarity enables it to dissolve a wide variety of substances, both ionic and some covalent compounds, by surrounding and separating the solute particles.
Question 3: An ionic bond is formed by the complete transfer of electrons from a metal to a non - metal, resulting in the formation of ions that are held together by electrostatic forces. A covalent bond is formed by the sharing of electrons between non - metal atoms to achieve a stable electron configuration.

Answer:

Question 1: Water striders float due to water's surface tension and their hydrophobic legs.
Question 2: Water is polar and can dissolve many substances.
Question 3: Ionic bonds involve electron transfer, covalent bonds involve electron sharing.
