How many grams of aluminum are needed to react completely with 1.25 x 1025 atoms of Fe2O3? The unbalanced equation is below: Al(s) + Fe2O3(s) --> Fe(s) + Al2O3(s)

0.88m hope i am correct : )

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.
