Question

1. how do the types of chemical bonds differ from each other? how are they similar? 2.2 properties of water 7. what are produced when a base is mixed with water? a. hydrogen ions b. hydroxide ions c. oxygen atoms d. oxygen ions 8. which type of bonds holds two or more water molecules together, as shown? a. covalent bonds b. van der waals forces c. hydrogen bonds d. ionic bonds

Explanation:

• For question 7: Bases dissociate in water to produce hydroxide ions. For example, sodium hydroxide (NaOH) dissociates into Na⁺ and OH⁻ in water.
• For question 8: Hydrogen bonds hold water - water molecules together. In water, the hydrogen of one water molecule is attracted to the oxygen of another water molecule through hydrogen - bonding.

Answer:

1. b. hydroxide ions
2. c. hydrogen bonds
