Please explain why as well Iron wool was heated in a glass tube, chlorine gas was passed over it and iron chloride formed. The glass tube had a mass of 46.43g, when the iron was added the mass went up to 47.74g. When the reaction was over the mass of the cooled tube and the iron chloride was 50.34g.
a. Find the mass of the iron used.
b. Find the mass of the chlorine added.
c. Find the formula of the iron chloride formed.
d. Write a balanced equation for the formation.
