How can I solve this using a T chart

The answer to your question is given below

Explanation:

The balanced equation for the reaction is given below:

2KClO₃ —> 2KCl + 3O₂

From the balanced equation above,

2 moles of KClO₃ decomposed to produce 2 moles of KCl and 3 moles of O₂.

Next, we shall determine the number of mole of KClO₃ that will decompose to produce 9 moles of O₂. This can be obtained as follow:

From the balanced equation above,

2 moles of KClO₃ decomposed to produce 3 moles of O₂.

Therefore, Xmol of KClO₃ will decompose to produce 9 moles of O₂ i.e

Xmol of KClO₃ = (2 × 9)/3

Xmol of KClO₃ = 6 moles

Thus, 6 moles of KClO₃ is needed for the reaction.

Next, we shall determine the number of mole KCl that will be produced by the decomposition of 6 moles of KClO₃. This can be obtained as follow:

From the balanced equation above,

2 moles of KClO₃ decomposed to produce 2 moles of KCl.

Therefore, 6 moles of KClO₃ will also decompose to produce 6 moles of KCl.

Finally we shall represent the reaction in a chart as illustrated below:

2KClO₃ —> 2KCl + 3O₂

6 moles —> 6 moles | 9 moles
