Which is not true about enantiomers? a. they have "handedness" b. nonsuperimposable mirror images c. symmetrical, with superimposable mirror images d. rotate plane polarized light in opposite directions

C

Explanation:

Enantiomers are molecules that are mirror images of one another. This means they have the same connectivity of the same atoms in the molecules but have an opposite 3-dimensional orientation – like the two palms of the hand.  This means they polarised light in opposite directions but with equal effect.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
