Answer:

The answer is C. a diol and a dicarboxylic acid

Explanation:

Because Esterification (formation of an ester) is a process that requires an alcohol to react with a carboxylic acid.

Polyester means many ester units.

one alcohol + one carboxylic acid make one ester

thus more than one of each functional groups will make more than on ester unit.

That is why diol (2OH functional groups) + dicarboxylic acid (2 Carboxyl groups) will make polyesters.

A sample of nitrogen gas is stored in a 489.6 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 28.7

Wewaii [24]

Answer:

P2= 125.26 Kpa

Explanation:

V1= 489.6 ml=0.4896L

V2= 750 ml= 0.750L

V1= 180 KPa= 180000 Pa

P2= ?

T1= 10 = 10 + 273.15 = 283.15K

T2= 28.7+273.15= 301.85K

180000Pa* 0.4896L/ 283.15K * 301.85K/0.75L

P2= 12526.28553

P2= 125.26 KPa
