Answer:
<u>Part -A:</u>
Sulfur released is .
<u>Part-B:</u>
released of per EPA norms is .
Explanation:
From the given,
The output = 1100 Mw
Efficiency = η = 0.4
Substitute the values in the following
Input = Output / η
Let's converts between joules to BTU.
1 BTU = 1056 J
<u>Part-A;</u>
But it has 2% sulfur
The mass of sulfur released
Therefore, released sulfur is .
<u>Part -B;</u>
One pound of sulfur produce two pounds of sulfur dioxide
Initial amount of produced sulfur =
Assuming we added a 80% efficiency then,
Released sulfur dioxide =
Energy produced in an hour =
Therefore, released of per EPA norms is .
Explanation :
According to the molecular orbital theory, the general molecular orbital configuration will be,
As there are 7 electrons present in nitrogen and 9 electrons in fluorine.
(a) The number of electrons present in molecule = 7 + 9 = 16
The molecular orbital configuration of molecule will be,
The formula of bonding order =
The bonding order of =
(b) The number of electrons present in molecule = 7 + 9 - 1 = 15
The molecular orbital configuration of molecule will be,
The bonding order of =
(c) The number of electrons present in molecule = 7 + 9 + 1 = 17
The molecular orbital configuration of molecule will be,
The bonding order of =
Answer:
b
Explanation:
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds.
All of the above is the correct choice
Answer:
The answer is: Chemical element
Explanation:
A chemical element refers to the chemical substance or species containing a fixed number of neutrons and protons in its nuclei. The atomic number of an element is equal to the number of protons.
All the matter present in the universe is composed of these chemical elements.The chemical and physical properties of the these elements are summarized in periodic table.
