Answer:
Ph-OH
Explanation:
Nitration of Aromatic compounds is an example for Aromatic Electrophilic substitution and its rate is enhanced by Electron donating group like OMe, OH, alkyl group and halides (least activating group) while reactivity is diminished by electron withdrawing like CN,NO2 and Ketone etc
Hence phenol is more reactive than benzene towards nitration.
Answer: Option (C) is the correct answer.
Explanation:
Biopower means production of electricity with the help of biomass. The unused wood, crops, agricultural residue, animal residue etc when burned then they help in generating biopower.
It is a renewable energy. Since biomass is readily available in most of the places. Therefore, the advantage of biopower is that it is also readily available in most places.
For example, bacterial decay produces a certain amount of heat which further helps in the production of energy.
Answer: D) All of the above
Explanation:
The sources of errors in the kinetic experiment are depends upon the tools, due to some personal errors and also due to some methodological problem. As, experimental error during kinetic study is due to the difficulty to characterize the experimental errors depend on reaction conditions. The behavior of the experimental errors are depend on specific feature of the experiment systems.
Answer:
84.2mL
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 128mL
Initial pressure (P1) = 500mmHg
Final pressure (P2) = stp = 760mmHg
Final volume (V2) =..?
Thus, the new volume of the gas can be obtained by using the Boyle's law equation as follow:
P1V1 = P2V2
500 x 128 = 760 x V2
Divide both side by 760
V2 = (500 x 128)/760
V2 = 84.2mL
Therefore, the new volume of the gas is 84.2mL
