NCO2= 0, 248 /44= 0 ,005636
VCO2= 0,005636* 22,4= 0 ,126254545
The correct answer is option B. Dirty water is a mixture of solid particles and liquid. It is both a mixture and pure substance.
The dirty water sample has both gravel and liquid water in it. After filtration the gravel is removed so the water sample looks clearer than before filtration. Liquid water is a pure substance because it is a compound that is made up of elements hydrogen and oxygen. Now the gravel is only physically combined with the liquid water, thus giving the water sample properties of a mixture. And like any mixture, gravel is physically separated through filtration from the liquid water.
Thus the water sample of the chemists is both a mixture and pure substance.
Answer: Theoretical yield of
produced by 8.96 g of S is 33.6 g
Explanation:
To calculate the moles :


The balanced chemical equation is:
According to stoichiometry :
2 moles of
produce = 3 moles of 
Thus 0.28 moles of
will produce=
of
Mass of 
Thus theoretical yield of
produced by 8.96 g of S is 33.6 g
