Answer:
2KClO3 》》2KCl +3O2
C+ O2》》CO2
number of C moles
Required O2 moles (According to the mole ratio )
Relevant to the first equation, find the moles the KClO3, which is used to produce that amount of O2 moles
Now you can find the mass of KClO3
I mentioned the useful steps which can guide you to get the answer.

Answer:
Distillation is an important commercial process that is used in the purification of a large variety of materials. However, before we begin a discussion of distillation, it would probably be beneficial to define the terms that describe the process and related properties. ... Elevation of the boiling point with an increase in external pressure, while important in cooking and sterilizing food or utensils, is less important in distillation.
Explanation:
There is an increase in the frequency of particle collisions which leads to the increased rate of the reaction.
<u>Explanation:</u>
Hydrochloric acid reacts faster with the powdered zinc than with the equal mass of zinc strips.
Since the surface area of the Zinc particle increases when it is powdered and has more active spots when compared to less number of active sites in Zinc strips and so the number of collision between the Zinc particles and the particles of Hydrochloric acid also increases and consequently the rate of the reaction also enhances.
So there is an increase in the frequency of particle collisions.
