As this is a secondary alcohol, it will oxidise to a ketone, in this q it is propanone.

CH3CH(OH)CH3 + [O] -> CH3COCH3 + H2O

You can identify that this is oxidation as the catalyst given is K2Cr2O7/ H2SO4. For this instance just turn the -OH group into a carbonyl -C=O and remove the H from the other side, as a carbon can only have 4 bonds. Hope this is useful

for your chemsheets question it should be CH3CH(OH)CH3 + [O] -> CH3COCH3

for partial oxidation of primary alcohols to aldehydes add [O]
for complete oxidation of primary alcohols to carboxylic acids write 2[O]
and for oxidation from aldehydes to carboxylic acids add [O]
