Question

Iron reacts with chlorine gas, Cl2, to form iron(III) chloride, FeCl3

Write the balanced equation for this synthesis reaction.

Answer 1

2Fe + 3Cl2 --> 2 FeCl3

Step-by-step explanation:

Fe + Cl2 --> FeCl3

iron is balanced but chlorine isn't so we find what number can make each one equal

Fe +3Cl2 --> 2FeCl3

now we need to balance iron

2Fe + 3Cl2 --> 2 FeCl3
