Question

1. 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 hold 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 question 8, hydrogen bonds hold multiple water - molecules together. Covalent bonds are within a single water molecule, van der Waals forces are weaker than hydrogen bonds in this context, and ionic bonds are not relevant for water - water interactions.

Answer:

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