= 
Explanation:
Tollens test is carried out to perceive difference between aldehydes and ketones on the basis of their capability to oxidized easily.
when Tollens react with aldehyde (heptanal) , a silver mirror is form on inner side of container.
The reaction between tollens and heptanal is given as
= 
CH2O3
C=19.36\12 = 1.61
H=3.25\1.008 =3.22
O=77.39\16=4.83
then dived the moles with the smallest mole
C=1.61\1.61=1
H=3.22\1.61=2
O=4.83\1.61=3
E.F
CH2O3
