A) Measure the pH of different household chemicals
Explanation:
To demonstrate a chemical property using an experiment, measuring the pH of different household chemicals will be the best way. The pH is the degree of hydrogen or hydroxyl ion concentration in a solution.
- Chemical properties tell us about what a substance can do.
- It shows if a substance will react with other substances or not.
- Examples are flammability, rusting of iron, precipitation, decomposition of water by electric current e.t.c.
- Measuring the pH is a chemical property determination procedure.
- The pH points to the degree of acidity or alkalinity of a solution.

I believe the answer your looking for is A. Flammability. Because flammability is a chemical property, not a physical one. Hope this helps :)
Answer:
F = 3750 N
Explanation:
Given that,
Pressure, P = 150 Pa
Area, a = 25m²
We need to find the force applied. We know that, pressure is equal to the force acting per unit area. It can be given by :
So, the required force is 3750 N.
Answer:
