Answer:
Dehydration reactions assemble polymers, and hydrolysis reactions break down polymers.
Explanation:
dehydration reaction is a conversion that involves the loss of water from the reacting molecule or ion.
Hydrolysis is defined as any chemical reaction in which a molecule of water ruptures one or more chemical bonds.
Dehydration reactions link monomers together into polymers by releasing water, and hydrolysis breaks polymers into monomers using a water molecule. Monomers are just single unit molecules and polymers are chains of monomers.

Answer:
Explanation:
a ) gauge pressure will be due to water column of length 15 cm .
pressure = h d g , h is height of column , d is density of column and g is gravitational acceleration .
= .15 x 10³ x 9.8
= 1470 Pa .
b )
Let due of weight of water column , mercury level in left column goes down by distance h . The level of mercury in right column will rise by the same distance ie by distance h .
So mercury column of 2h height is balancing the water column of height 15 cm
2h x 13.6 x 10³ x g = .15 x 10³ x g
h = .15 / (2 x 13.6)
= .55 x 10⁻² m
= . 55 cm
Difference of height of water column and mercury column
= 15 - 2 x .55 cm
= 13.9 cm .
