Nitrobenzene contains 5 hydrogen atoms, 6 carbon atoms, 2 oxygen atoms, and 1 nitrogen atom. what is the chemical formula for ni

ollegr [7]

C₆H₅NO₂

<h3>Further explanation</h3>

Nitrobenzene contains:

5 hydrogen atoms,
6 carbon atoms,
2 oxygen atoms, and
1 nitrogen atom.

The chemical formula for nitrobenzene is C₆H₅NO₂.

Nitrobenzene is one of benzene derivatives, precisely including the type of monosubstituted benzenes.

The molecular structure of phenyl $\boxed{ \ C_6H_5- \ }$ is formed by removing one H atom from the benzene $\boxed{ \ C_6H_6 \ }$ molecule. A substituent is bound to the C atom which loses the H atom so it is called monosubstituted benzene.

In the naming of monosubstituted benzenes, benzene is the parent name and the substituent is indicated by a prefix.

nitro is the substituent
benzene is the parent name

When benzene is reacted with a mixture of concentrated nitric acid and concentrated sulfuric acid, it yields nitrobenzene.

$\boxed{ \ C_6H_6 + HNO_2 \ (with \ H_2SO_4 \ in \ 30^0C-40^0C) \rightarrow C_6H_5NO_2 + H_2O}$

<u>Notes:</u>

Benzene and compounds having similar chemical properties to benzene are called aromatic compounds.
Benzene is a colorless, poisonous liquid with a specific odor. it dissolves in organic solvents in organic solvents such as alcohol, ether, and acetic acid. Benzene is also good for non-polar substances.
Nitrobenzene is used in the manufacture of aniline and other organic chemicals. Nitrobenzene is a pale yellow, oily, and highly toxic liquid with the odor of bitter almonds.

Answer:

Answer:A

Answer:AExplanation:

Answer:AExplanation:Molar Mass of glucose = (6×12)+(1×12)+(16×6)= 180g/mol

= 180g/molNumber of moles of Glucose = Mass/Molar Mass

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778moles

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1Therefore the number of moles of ethanol is 2×27.7778

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1Therefore the number of moles of ethanol is 2×27.7778=55.5556moles

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1Therefore the number of moles of ethanol is 2×27.7778=55.5556molesMass of ethanol= Molar Mass of ethanol × Number of moles

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1Therefore the number of moles of ethanol is 2×27.7778=55.5556molesMass of ethanol= Molar Mass of ethanol × Number of moles={(12×2)+(1×6)+16} × 55.5556

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1Therefore the number of moles of ethanol is 2×27.7778=55.5556molesMass of ethanol= Molar Mass of ethanol × Number of moles={(12×2)+(1×6)+16} × 55.5556= 46.5×55.5556

= 180g/molNumber of moles of Glucose = Mass/Molar Mass= 5000/180= 27.7778molesIn the balanced equation of fermentation, the ratio of glucose to ethanol is 2:1Therefore the number of moles of ethanol is 2×27.7778=55.5556molesMass of ethanol= Molar Mass of ethanol × Number of moles={(12×2)+(1×6)+16} × 55.5556= 46.5×55.5556= 2555.55
