Which of these salts is most soluble at 50°c? kno3 nano3 kclo3 nacl

NaNO₃.

Explanation:

It is 90 g per 100 g water.

It is 110 g per 100 g water.

It is about 20 g per 100 g water.

It is about 40 g per 100 g water.

So, the most soluble salt at 50°C is NaNO₃.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
