Answer: C. surface area and fluid drag
Explanation:
Surface area is not important when one is dealing with pressure drag, but it is important when dealing with viscous drag — drag caused by layers of the fluid sticking to the object and to one another. More surface area means more of the object is in contact with the fluid, which means more drag.
For a 35.83 g sample of potassium chlorate, the mass of potassium chloride is mathematically given as
M Kcl=21.62g
<h3>What is the mass of potassium chloride you expect to release upon heating?</h3>
Generally, the equation for the Chemical Reaction is mathematically given as
2KClO_3----->2KCl+2O_2
Therefore
Mole of KCl=0.29mol
Mass of Kcl=0.29*74.55
Mass of Kcl=21.62g
In conclusion, Mass of Kcl
M Kcl=21.62g

To determine the number of atoms of a substance given its number of mols, multiply number of moles with the Avogadro's number which is approximately equal to 6.022x10^23.
To answer the problem above, multiply 3.50 mols with <span>6.022x10^23. This gives a product of 2.1077x10^24.
Thus, there are </span><span>2.1077x10^24 atoms of sulfur in 3.50 mols of sulfur. </span>
