Answer 1

questions 10 and 11 are multi choice questions

Answer 2

Here are the answers to your questions:

**Question 10**: Which of the following is a characteristic of an acid?
- **c** donates protons (Acids are defined as proton donors according to the Brønsted-Lowry theory.)

**Question 11**: Which of the following is a characteristic of a base?
- **b** feels slippery (Bases are known to feel slippery, and they can also accept protons or donate hydroxide ions.)

**Question 12**: A solution with a pH of 9 would be acidic.
- **False** (A pH of 9 is considered to be basic/alkaline, not acidic.)

**Question 13**: A substance with a pH of less than 7 is a base.
- **False** (A substance with a pH of less than 7 is classified as an acid.)

Answer 3

Thank you for the clarification! Here are the answers considering each option:

**Question 10**: Which of the following is a characteristic of an acid?
- **a** accepts protons (False; this describes bases according to Brønsted-Lowry theory.)
- **b** tastes sour (True; many acids have a sour taste.)
- **c** donates protons (True; according to the Brønsted-Lowry theory, acids are proton donors.)
- **d** feels slippery (False; this characteristic refers to bases.)

So, the correct answers are **b** and **c**.

**Question 11**: Which of the following is a characteristic of a base?
- **a** tastes sour (False; this describes acids.)
- **b** feels slippery (True; bases typically feel slippery to the touch.)
- **c** donates protons (False; bases accept protons according to the Brønsted-Lowry theory.)
- **d** accepts protons (True; bases are defined as proton acceptors.)

So, the correct answers are **b** and **d**.
