Answer:
D. The electron-withdrawing fluorine atoms pull electron density from the oxygen in trifluoroacetate. The negative charge is more stabilized in trifluoroacetate by this effect.
Explanation:
The structures of trifluoroacetate and acetic acid are both shown in the image attached.
The trifluoroacetate anion (CF3CO2-), just like the acetate anion has in the middle, two oxygen atoms.
However, in the trifluoroacetate anion, there are also three electronegative fluorine atoms attached to the nearby carbon atom attached to the carbonyl, and these pull some electron density through the sigma bonding network away from the oxygen atoms, thereby spreading out the negative charge further. This effect, called the "inductive effect" stabilizes the anion formed,the trifouoroacetate anion is thus more stabilized than the acetate anion.
Hence, trifluoroacetic acid is a stronger acid than acetic acid, having a pKa of -0.18.
well, worms break down dead plants and bacteria can break down animal flesh and plants. Hope this helps :)
Hello!
You need to calculate the volume of the container. To calculate the volume of this amount of N₂ gas we need to make the assumption that N₂ behaves like an
ideal gas.
1 mole of an ideal gas under Standard Temperature and Pressure occupies
22,4 L so the calculations are as follows:
So, the volume of the container should be
1,028 L or more.
Have a nice day!
Ash cloud from a volcano can greatly affect so many systems
in the earth. The flow of matter is greatly affected by energy because without
energy matter does not move. The cloud of valcano affects cycle of energy
because it blocks the energy of the sun the enters the earth which will result
to reducing temperature. Example of it the erruption of mt. pinatubo in ph, the
earth temperature substanctailly reduces. The ecosystem will greatly be
affected due to different temperature and different weather pattern that will
occur that will be new to the orgnisms.
Im sorry but Chapter 2 test chemistry doesnt sound much like a question can you be more specific thanks ik u can be more specififc!
