Question

One mole of potassium chlorate is thermally decomposed and excess of aluminium is burnt in the gaseoues product. How many mole of aluminium oxide formed

Answer 1

Explanation:

1 mole of KClO3 is thermally decomposed & excess of aluminium is burnt in the gaseous product. how many moles of Al2O3are formed? Answer: Two reactions occur here are the thermal decomposition of KClO₃ and the subsequent oxidation of Aluminum to form Al₂O

Answer 2

Heya!!

KClO3→KCI +3/2 O2

For one obtains 3/2 moles of O2 which will combines with just 2 moles of Al as shown below

2Al + 3/2 O2 →Al2O3.

Hence, 1 mole is the required answer.

Thanks!!
