Answer:
The PH2 becomes attached to the alkyl halide with inversion of configuration
Explanation:
SN2 reaction involves the simultaneous attachment of the nucleophile as the leaving group departs. This leads to an inversion of configuration because the sterochemistry around the carbon bearing the leaving group is reversed. The reaction proceed via a crowded five coordinate transition state. Details are shown in the image attached.
Answer:
C meteoroid
Explanation:
Meteoroids are the only ones of the four that are under a kilometer in size.
383 mL of 3.50 M muriatic acid solution
Explanation:
First we calculate the number of moles of HCl:
number of moles = mass / molecular weight
number of moles of HCl = 47.7 / 35.5 = 1.34 moles
Now to determine the volume of the 3.50 M muriatic acid (clorhidric acid) solution, we use the following formula:
molar concentration = number of moles / volume (L)
volume (L) = number of moles / molar concentration
volume of the muriatic acid solution = 1.34 / 3.5 = 0.383 L = 383 mL

Answer:
The configuration of the atom would be 2-8-2.
Explanation:
Any atom of an element combines with other element to complete its octet and become stable.
The electron configuration of the given atom is 2-8-6. That means the atom has 6 electrons in its outermost shell. To become stable the atom should have 8 electrons in its outermost shell. The given atom has 6 electrons so it either lose 6 electrons or gain 2 electrons to complete its octet.
But we know the atom having 5,6,7 electrons in its outermost shell they do not lose, they gain either 3 or 2 or 1 electrons to complete its octet.
So we say that atom with the electron configuration 2-8-6 bond with the atom having electron configuration 2-8-2.
<span>The correct answer is Beryllium. They all belong to atoms that have low electronegativity, and as you go down the group the farther away you are the lower it gets. This means that they are not good at bonding with and attracting pairs of electrons. Berryllium has an electronegativity of 1.5, which is low compared to Fluorine, the highest one that has 4.</span>
