<span>I don't know if my expression is right but: 25g NH3 x 1 mol/17.04g NH3 x 6.022x10^23 molecules NH3/mol NH3.</span>
Answer:
0 net force it is balanced
Explanation:
If the amount of force is the same on both sides the net force equals 0
Answer:
B
Explanation:
I think that's it.. hope I helped you
Answer:
See explanation
Explanation:
The electrophilic substitution of aromatic compounds occurs faster in substituted aromatic compounds due to the fact that the ring becomes more or less susceptible to electrophilic attack depending on the nature of the substituent in the ring.
Electron pushing substituents such as alkyl groups stabilize the positive charge developed during electrophilic substitution hence they activate the ring towards electrophilic substitution.
The methyl group is an ortho - para directing substituent hence the product obtained by nitration of toluene is o-nitrotoluene and p-nitrotoluene.
The stepwise mechanism for obtaining these products is shown in the image attached to this answer.
C₆H₆ + 3H₂ → C₆H₁₂
Benzene + 3 molecules of hydrogen = cyclohexane
So essentially what happens is that benzene contains three double bonds and when reacted with hydrogen then these three double bonds can be broken and the hydrogen bond to the tetravalent carbon to restore its for bonds forming cyclohexane
