<span>2 KClO3(s) → 3 O2(g) + 2 KCl(s)
</span><span>Note: MnO2 (Manganese Dioxide) is not part of the reaction. A catalyst lowers the activation energy and increases both forward and reverse reactions at equal rates.
</span>
molar mass of KClO3 = 122.5
Moles of KClO3 = 3.45 / 122.55 = 0.028
Moles of O2 produce =
= 0.042 moles
molar mass of O2 = 32
so, mass of O2 = 32 x 0.042 = 1.35 g

Answer:
The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.
Explanation:
The carbon footprint of one plastic bottle can be estimated by simple rule of three. That is:
The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.
