Slavery played a big role in this. the confederacy allowed slavery while the union was oppose to it.
This allows us to visually see the structure of the atoms/ molecules so we can get a better understanding of what they look like.
The element is Magnesium
- It has total 12 electrons
it has electronic configuration

or

In valence cell it has 2 electrons and therefore its valency is 2
Answer:
Explanation:
Diethyl malonate is more acidic than monocarbonyl compounds (pKa=13) due to their alpha hydrogens being attached to two carbonyl groups. Thus, the <u>malonic ester is easily converted to its enolate ion by reaction with sodium ethoxide in ethanol</u>. The product of the alkylation of the malonic ester leaves a <u>hydrogen atom acid in an alpha position</u>, so the alkylation process can be repeated a second time to produce a dialkylated malonic ester.
In this case, when urea is treated with diethyl malonate in the presence of sodium ethoxide base,<u> the second alkylation step occurs intramolecularly</u> to generate a cyclic product, barbituric acid.
