Chlorobenzene would essentially be a benzene ring that is substituted with chlorine. Thus it would have 6 carbon atoms, in its molecular formula.
Answer:
a) positive feedback
Explanation:
positive as in increasing

Br
Explanation:
To calculate the valance electrons, look at the periodic table to find the valance electrons for each atom and add them together. P is in column 5A, so it has 5, Br is in column 7A, so it has 7 (multiply by 4 since there are 4 Br atoms to give 28) and there is a 1- charge, so add one more electron. 5+28+1=34, so there are 34 electrons to place. P would be the central atom, so place it in the middle. Place each Br around the P (as shown above) with a a single line connecting it. Each line represents 2 electrons, so 8 total have been place, leaving 26 remaining. Place 6 electrons around each Br (2 on each of the unbonded sides), which leaves 2 electrons remaining. The remaining pair of unbound electrons will be attached to the P between any two Br atoms. Phosphorus doesn't have to follow the octet rule, so it actually ends up with 10 valance electrons.
It seems that you have missed the given options for this question which are the following: <span>A. glacial striations B. terminal moraines C. eskers D. cirques
Anyway, the correct answer would be option B. The one that are formed as glaciers retreat and leave debris behind in mounds at the front of their farthest advance are terminal moraines. Hope this answer helps.</span>
<span> </span>the egg white or albumen becomes denatured plus you can't reverse the cooking of an egg. hope that helps
