Answer:d.break them down to monosaccharides

Explanation:

Polysaccharides are polymers made of monosaccharide monomers. The polysaccharides do not release energy except the monosacharides are broken down to monosaccharides by stepwise hydrolysis. To obtain energy from polysaccharides, the constituent monosacharides are obtained and these are now involved in the biological cycles that liberate energy.

A liquid mixture contains 1 kg of water, 1.9 lb of ethanol, and 4.6 lb of methyl acetate. What is the weight fraction of ethanol

slamgirl [31]

Answer: The weight fraction of ethanol in the mixture is

Explanation:

We are given:

Mass of water = 1 kg = 2.205 lb (Conversion factor: 1 kg = 2.205 lb)

Mass of ethanol = 1.9 lb

Mass of ethyl acetate = 4.6 lb

Mass of mixture = [2.205 + 1.9 + 4.6] = 8.705 lb

To calculate the percentage composition of ethanol in mixture, we use the equation:

$\%\text{ composition of ethanol}=\frac{\text{Mass of ethanol}}{\text{Mass of mixture}}\times 100$

Mass of mixture = 8.705 lb

Mass of ethanol = 1.9 lb

Putting values in above equation, we get:

$\%\text{ composition of ethanol}=\frac{1.9lb}{8.705lb}\times 100=21.8\%$

Hence, the weight fraction of ethanol in the mixture is 21.8 %
