Answer:
Argon has three electron shells. The third shell is filled with eight electrons. That is why it does not easily combine with other elements.
Explanation:
The given word equation is:
Nitrogen trifluoride-->Nitrogen + Fluorine
The chemical formula of nitrogen trifluoride is 
and that of nitrogen gas is 
and fluorine gas is 
.
The balanced chemical equation representing the decomposition reaction of nitrogen trifluoride to nitrogen and fluorine will be,
The chemical formula of fluorine gas will be as fluorine exists as a diatomic gas in it's pure state. The coefficient of fluorine will be 3
Therefore, the correct answer is a) 3F2
Answer:
A A B
Explanation:
I know that when it is slopped it is 90% always accelerating
Answer: 0.035 moles FeF3 or 3.5x10-² moles FeF3
Explanation: 1 mole of FeF3 is equal to its molar mass ( 113g FeF3)
4.0g FeF3 x 1 mole FeF3 / 113 g FeF3 = 0.035 moles of FeF3
Answer:
Reluctantly she pulled away, her pulse and respiration in a race.
Its function is less that of respiration than of FIG
Terrestrial plants have a gaseous interchange of oxygen and carbon dioxide which is necessary for respiration and feeding.
The least wind raises clouds of fine dust, which fill the air, render it so opaque as to obscure the noonday sun, and make respiration difficult.
