Answer:
B
Explanation:
you're moving the decimal 8 spots to the left so it can only be B
Answer:
55
Explanation:
25g is less dense than 80g therefore will mostly float. if you subtract 80-25 that will leave you will 55 as the difference
As can be seen in the attached image, α-pyrone has a highly electrophilic carbon atom, since it is attached to two oxygen atoms that are electronegative and subtract electrical charge from the carbon, leaving it with a <u>positive partial charge</u>. By virtue of the above, <u>the bromine atoms, which have an important electron density that makes them good nucleophiles, will be attracted to the aforementioned carbon due to their positive charge</u>, thus favoring the substitution product to a greater extent than that of addition.
