Why all monosacharides and dissacharides are soluble in waters​

Monosaccharides are quite soluble in water because of the numerous OH groups that readily engage in hydrogen bonding with water.

Explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
