Answer:
c) more particles collide with the walls of the container
Explanation:
More moles means more particles. If the volume remains the same, the collisions of more particles with the container walls cause the pressure to increase.

Answer:
evaporation
Explanation:
The process of evaporation is as a result of water absorbing energy from the sun.
The process is a phase change in which liquid water changes into gaseous form.
- The water in gaseous form is called vapor
- This water cools and condenses in the atmosphere as it loses the energy it has gained.
- For evaporation to take place, water must absorb energy from the sun or other heating bodies.
- This will then cause vaporization of the liquid water into a gaseous form.
Answer:
It has no fixed shape and therefore takes the shape of the part of the container in which it is placed
Answer:
1.750 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 7.14 mL
M₂ = 0.250 M
V₂ = 50 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 7.14 mL = 0.250 M * 50mL
M₁ = 1.750 M
Hence, the molarity of the hydrochloric acid = 1.750 M
