Explanation / Answer

Ans 1 :

To write the balanced reactions , start by writing the species on both the sides of the reaction.

Then note down the elements on each side and then try to make them equal on each side of the reaction.

So the balanced reaction is given as :

2KClO3 = 2KCl + 3O2

b) 2 moles of KClO3 makes 3 moles of O2

So 12.00 moles of KClO3 will produce ( 12 x 3) / 2

= 18.00 moles of O2
