Which laws can be combined to form the ideal gas law?
Morgarella [4.7K]
Answer: Charles's law, Avogadro's law and Boyle's law.

Justification:

Boyle's law states that at constant temperature  PV = constant

Charles law states that at constant pressure V/T = constant

Avogadro's law states that at constant pressure ant temperature, equal volume of gases contain equal number of moles: V/n = constant

Ideal gas law states PV/nT = constant => PV = nT*constant = PV = nTR

Draw a mechanism for this reaction. 5-hydroxypentanoic acid forms 2-oxanone in the presence of acid. draw all missing reactants
Licemer1 [7]

Answer: -

The first step involves protonation of the carbonyl oxygen.

After protonation, the Alcohol oxygen now attacks the carbon of the carbonyl.

Thus a six membered ring is formed with 5 carbon atoms and 1 oxygen atom. The 1st position carbon atom has 2 OH groups.

One of these gets again protonated.

This leaves as water. With the loss of the H+, there results a carbonyl at 1 position.

Thus 5-hydroxypentanoic acid forms a lactone or 2-oxanone in presence of acid.
