Skeleton Equations
Skeleton Equations are equations that are unbalanced, meaning they do not
have an equal amount of each element on both sides of the equation
Any diatomic element found by itself must have a subscript of 2!
Task #1: Covert the following word equations into skeleton equations and then balance them.
Example: Silver nitrate + copper  silver + copper(II) nitrate
Solution: 2AgNO3 + Cu  Ag + Cu(NO3)2
(a) Iron + sulphur  Iron(II) sulphide

(d) Aluminum oxide  aluminum + oxygen
____________________________________________________________________________________
(e) Hydrogen + oxygen  water
