#1
Front (Question)

oxidation

Back (Answer)

increase in oxidation number gain of oxygen loss of hydrogren loss of electrons

#2
Front (Question)

reduction

Back (Answer)

decrease in oxidation number loss of oxygen gain of hydrogen gain of electrons

#3
Front (Question)

redox reaction

Back (Answer)

one in which there are changes in oxidation number

#4
Front (Question)

oxidising agent

Back (Answer)

oxidises another species reduced itself takes electrons

Front (Question)

reducing agent

Back (Answer)

reduces another species oxidised itself forces its electrons onto other species

#17
Front (Question)

reactivity

Back (Answer)

how easily something reacts

#18
Front (Question)

best metallic oxidising agent

Back (Answer)

less reactive bc easier to gain electrons

#19
Front (Question)

best metallic reducing agent

Back (Answer)

more reactive bc easier to lose electrons
