What is the final volume (L) of a 1.00 L system at 315 K and 1.10 atm if STP conditions are established?
LenaWriter [7]

Answer:

0.95L

Explanation:

Data obtained from the question include:

V1 (initial volume) = 1L

T1 (initial temperature) = 315K

P1 (initial pressure) = 1.10 atm

T2 (final temperature) = stp = 273K

P2 (final pressure) = stp = 1atm

V2 (final volume) =?

Using the general gas equation P1V1/T1 = P2V2/T2, the final volume of the system can be obtained as follow:

P1V1/T1 = P2V2/T2

1.1 x 1/315 = 1 x V2/273

Cross multiply to express in linear form.

315 x V2 = 1.1 x 273

Divide both side by 315

V2 = (1.1 x 273) /315

V2 = 0.95L

Therefore, the final volume of the system if STP conditions are established is 0.95L

Draw the carboxylic acid produced from the acid hydrolysis of butyl acetate.
Nat2105 [25]

Answer:

Acetic or ethanoic acid.

Explanation:

Hello,

Butyl acetate's hydrolisis is shown below:

CH_3COOCH_2CH_2CH_2CH_3+H_2O-->CH_3COOH+CH_3CH_2CH_2CH_2OH

Whereas CH_3COOCH_2CH_2CH_2CH_3 is the butyl acetate, CH_3CH_2CH_2CH_2OH butanol and CH_3COOH the required produced acid, acetic or ethanoic acid (attached picture).

Best regards.
