3. What is the energy of a photon corresponding to microwave radiation of frequency 1.258 X 1010 s-1

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

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.
