An enantiomer is presented below in a 3D structure and in an unfinished 2D representation. a) On the 3D structure, select – by clicking on – the chirality center. A selected atom will be outlined in blue. b) Examine the 3D structure below to determine the stereochemistry of the chiral molecule. Then, on the corresponding 2D structure, draw one wedge bond and one dash bond over two existing bonds to indicate the correct stereochemistry. The narrow part of each wedge-and-dash bond should be towards the chirality center.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
