Poly(lactic acid) (PLA) has received much recent attention because the lactic acid monomer [CH3CH(OH)COOH] from which it is made

can be obtained from carbohydrates rather than petroleum. This makes PLA a more "environmentally friendly" polyester. Draw the structure of PLA.

Answer:

The structure is shown in the figure.

Explanation:

There is condensation polymersiation in case of lactic acid with the removal of water molecule (dehydration) leading to formation of poly lactic acid.

The structure of PLA is shown in the figure.

Tems11 [23]

Answer:

Following are the explanation to this question:

Explanation:

The salts of carboxylate are named by the writing, which is also named as the creation of the first, which is followed by the name of the carboxylic acid were '-ic' of the acid end and replaced by the 'ate'.

Following are the description of the given reaction:

In reaction A:

2-Bromopropanoic acid= C_3H_5BrO_2

C_3H_5BrO_2+NaOH⇄ C_3H_4BrNaO_2 +H_2O

The IUPAC name is Sodium-2-Bromopropanate

In reaction B:

2-Methylhexanoic acid= C_7H_{14}O_2

C_7H_{14}O_2+NaOH⇄ C_7H_{13}NaO_{2}+H_2O

The IUPAC name is Sodium-2-Methyl hexanoate

How many moles of a gas sample are in a 20.0 L container at 373 K and 203 kPa? The gas constant is 8.31 L−kPa/mol−K. A)0.33 mole
12345 [234]

Answer:

Option (C) 1.30 moles

Explanation:

The following data were obtained from the question:

Volume (V) = 20L

Temperature (T) = 373K

Pressure (P) = 203 kPa

Gas constant (R) = 8.31 L.kPa/mol.K.

Number of mole (n) =...?

The number of mole of the gas in the container can obtained by applying the ideal gas equation as illustrated below:

PV = nRT

Divide both side by RT

n = PV /RT

n = 203 x 20 / 8.31 x 373

n = 1.30 mole.

Therefore, 1.30 mole of the gas is present in the container.
