Nacgat Helga NH3(g)N2(g)+H2(g) Nh3(g)​

6.4 cm (max) - 25 cm (min)

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

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.
