If the uncompressed gas in the above system has a volume of 300.0 mL at a pressure of 20.0 kPa, what is the volume of the gas when it is compressed to a pressure of 25.0 kPa?

240 mL

Explanation:

(20 kPa)(300 mL) = (25 kPa)V2

V2 = 240 mL

Or my way which was

300 mL / 25 kPa =12

12(5)=60

300-60=240mL

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
