Use the reactions given below to determine the ∆H^o rxn in kJ/mol rxn. ½ H2(g) + ½ I2(s) → HI(g) ∆H = 26 kJ/mol rxn
½ H2(g) + ½ I2(g) → HI(g)∆H = −5.0 kJ/mol rxn

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

wanswer:

explanation:

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.
