Chemistry has taught that ;
Unsaturated hydrocarbon molecules that contain one or more double bonds are called alkenes.
Alkynes are unsaturated hydrocarbons due to the fact that some of the carbons are connected to fewer than four neighbouring atoms.
Note : Alkenes contain at least one double bond, while alkynes contain at least one triple bond.
Explanation:
The proper word equation for
4Fe + 3Sn(NO3)4 = 4Fe(NO3)3 + 3Sn is as below
Iron + Tin (iv) nitrate = iron(iii) nitrate + Tin
iron displaces tin from it compound ( Tin (iv) nitrate to form iron (iii) nitrate and tin.
from the equation above 4 moles of Fe displaces 3 moles of Sn(NO3)4 to form 4 moles of Fe(NO3)3 and 3 moles of SN
