8. Conclusions Why is it helpful to know how much carbon monoxide (CO) was produced, even though silicon is the product being collected for industrial use?

Answers

Answer 1

Answer: It is helpful to know how much carbon monoxide (CO) was produced because it signifies incomplete combustion therefore can represent inefficiency of the process and also carbon monoxide is an air pollutant it is very important to control the emission of this gas.

"For a many-electron atom, which of the following sublevels has the highest energy? A. 3p. B. 3d. C. 3s. D. 4s".

Answers

Empty 4s orbitals are slightly lower in energy than empty 3d orbitals however, in the context of this question, in a many electron atom where the 4s orbitals are filled, they are repelled to a higher energy level than 3d orbitals and hence the answer should be D.

Considering the law of conservation of mass, if 56 g samples of solid iron (Fe) reacts with 24 g of oxygen (O2), how many grams of Iron Oxide (FeO) are obtained?

Answers

Answer:

62_grams of FeO

Explanation:

Molar mass of Fe = 55.845_g/mol

Molar mass of O2 = 15.999_g/mol

From law of conservation of mass

2 moles of Fe combines with one mole of O2 to form 2 moles of FeO

Number of moles of Fe and O2 present = mass/(molar mass) = 56/55.845~1

and 24/16 = 1.1.5

Therefore

1 part of Fe will react with 0.5 part of one mole of O2

which is 54_g of Fe reacts with 8_g to form 54+8 = 62_grams of FeO
