i. Oxidation is an increase in the oxidation number of an element in a given substance.

e.g. Fe(s)  → \(Fe_{(aq)}^{2+}\)

ii. Reduction is a decrease in the oxidation number of an element in a given substance.

e.g. \(Cu_{(aq)}^{2+}\) → Cu(s)

In a senior secondary school,80 students play football or hockey.The number that play football is 5 more than twice the number that play hockey.If 15 students play both games and every student in the school plays at least one game,find (i)the number of students that play football (ii)the number of students that play football but not hockey (iii)the number of students that play hockey but not football.

I thought F or H = 80 is giving by n(F u H) = n(F) + n(H) - n(F n H)

Define oxidation number.

It is defined as the charge that an atom of the element has in its ion or appear to have when present in the combined state with other atoms.
