Answer:

b.  in the oscillating electric and magnetic fields

Explanation:

Electromagnetic waves are formed when mutually perpendicular electric and magnetic field oscillate in space. Electromagnetic waves carry electromagnetic radiant energy from the electromagnetic filed. Electromagnetic waves do not require a medium to propagate. The direction of propagation of the electromagnetic wave is perpendicular to the direction of the vibrating electric and magnetic field.

Vladimir [108]
The solution to your problem is as follows:

 <span>2 KClO3 → 2 KCl + 3 O2 

</span><span>MW of KCL = 39.1 + 35.35 = 74.6 g/mole 

62.6/74.6 = 0.839 moles KCl produced 

0.839 moles KCl x 3O2/2KCl x 32g/mole O2 = 40.27g of O2 was produced
</span>
Therefore, there are <span>40.27g of O2 produced during the reaction.
