What is a closed system in chemistry? what is an open system in chemistry? plzz dont make the answer too smart so dumb it down a lil.

A open system is a system that exchanges energy and matter with its surroundings.

A closed system is a system that exchanges energy only with its surroundings, not matter.

hopefully my answer helps! ♡

if my answers helped you please tell me, therefore I know.. that I did them correctly or incorrectly. anyways, have a great day/night!

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
