Sodium reacts vigorously with water while potassium, the next element down in Group I, has a faster reaction rate. What would you expect of the rate of reaction of elements further down in Group I when exposed to water? a. They would react with the same rate as potassium.
b. They would react much faster than sodium or potasssium.
c. They would react more slowly than potassium.
d. The rate of reaction would be unpredictable

c. They would react more slowly than potassium. It's because sodium reacts slowly with water!

Explanation:

i am giving you the answer according to the doubtnut channel!

c. They would react more slowly than potassium.

Because their ability to displace hydrogen will be less.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
