Explain the relationship between monomers and polymers using polysaccharides as an example
Mars2501 [29]

Answer:

Glucose and glycogen.

Explanation:

Hello,

Monomers are the functional molecules forming the polymers when an random amount of units (monomers) are linked form an assembly (polymer).

This could be exposed by considering the glucose as the monomer forming the glycogen which is a polymer that serves as a form of energy storage in animals, fungi, and bacteria; it is constituted by about 30,000 units of both lineal and branched glucose which provide many features that the glucose doesn't have by itself.

Best regards.

If 60.0 grams of carbonic acid are sealed in a 2.00 L soda bottle at room temperature (298 K) and decompose completely via the e
Tresset [83]

Answer:

The final pressure of the carbon dioxide gas will 11.84 atm.

Explanation:

Moles of carbonic acid = \frac{60.0 g}{62 g/mol}=0.9677 mol

H_2CO_3(aq)\rightarrow H_2O(l) + CO_2(g)

According to reaction, 1 mol of carbonic acid gives 1 mole of carbon dioxide gas.

Then 0.9677 moles of carbonic acid will give :

\frac{1}{1}\times 0.9677 mol=0.09677 mol of carbon dioxide

Moles of carbon dioxide gas = n = 0.09677 mol

Volume of soda bottle = V_1=2 L

Pressure of the carbon dioxide gas = P

Temperature of the carbon dioxide gas = T = 298 K

PV=nRT (ideal gas law)

P=\frac{nRT}{V}=\frac{0.9677 mol\times 0.0821 atm L/mol K\times 298 K}{2 L}=11.84 atm

The final pressure of the carbon dioxide gas will 11.84 atm.
