Oxygen can be preparead in a lab by the reaction:
2KCLO3 = 2H2(g) + O2(g)
Question: How many grams of KCLO3 must be reacted to produce 100 g of O2?
You cannot prepare O2 by the "reaction" given in the question.
<br>Actually the chemical reaction for the preparation of o2 in the laboratory is
<br>2KClO3 --> 2KCl + 3O2
<br>From this we ...
