Answer:
molecular
Explanation:
Answer:
47911.1 pa
Explanation:
The SI base unit of pressure is pascal, which is N/m^2.
2200 kg is 2200*9.8=21560 N, and 4500 cm^2=4500/10000=0.45 m^2.
So the total pressure exerted on the ground (!!) is 21560/0.45= 47911.1 Pa.

- Bases have a bitter taste.
- Bases feel slippery.
- Bases conduct electricity when dissolved in water.
- Bases change litmus paper from red to blue in colour.
- They react with acids to form a salt and water, this process is called neutralisation.
