Answer: air
Explanation:since individual components of air cannot be identified by merely looking at it, it is a homogeneous mixture.
Since gas molecules average velocity depends on temperature, oxygen molecules at 25°C are moving faster than oxygen molecules at 0 °C.
According to the kinetic theory of gases, the molecules of a gas are in constant random motion and collide frequently with each other and the walls of the container.
The average speed of gas molecules depends on temperature and molar mass as shown by the relation;
vrms = √3RT/M
The following statement are true among the options provided;
- Oxygen molecules at 25°C are moving faster than oxygen molecules at 0 °C
- Gases exert pressure by colliding with container walls
The following are false among the options provided;
- All hydrogen molecules are moving with the same velocity
- Nitrogen gas exerts more pressure than hydrogen gas because nitrogen molecules are heavier than hydrogen molecules.
- Nitrogen molecules remain suspended in the atmosphere because they are not attracted to Earth by gravitational forces.

when Cl2 is dissolved in water it generates ClO which is a good oxidizing agent since it gives out atomic oxygen. but dissolution of F2 cannot generate atomic oxygen since F is more electronegative than O
Answer:
ion exchange is the exchange of ions of the same charge between an insoluble solid and a solution in contact with it, used in water-softening and other purification and separation processes.
