Q1

A teacher investigated the reaction of iron with chlorine using the apparatus

in the above diagram.

The word equation for the reaction is:

iron + chlorine → iron chloride

The teacher weighed:

• the glass tube

• the glass tube and iron before the reaction

• the glass tube and iron chloride after the reaction.

Table 2 shows the teacher’s results.


Calculate the simplest whole number ratio of:

moles of iron atoms : moles of chlorine atoms

Determine the balanced equation for the reaction.

Relative atomic masses (Ar): Cl = 35.5 Fe = 56

    Moles of Fe = 4.48 ÷ 56 = 0.08
    Moles of Cl = 8.52 ÷ 35.5 = 0.24

    Ratio of Fe : Cl = 0.08 : 0.24 = 1 : 3

    Balanced equation:
    2Fe + 3Cl₂ → 2FeCl₃

  1. Moles of Fe = 4.48 ÷ 56 = 0.08
    Moles of Cl = 8.52 ÷ 35.5 = 0.24

    Ratio of Fe : Cl = 0.08 : 0.24 = 1 : 3
