Answer:
[AR] 4s². EC(Ca)=1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
S=shell
²or⁶ is number of electrons
Explanation:
the number of electrons for the calcium atom is 20 show the first two electrons of calcium will go in the 1s² orbital. the next two electron will go in the 2s orbital and the next 6 electron will go in the 2p orbital.

subtract the answer it'll get you that.
Explanation:
I think its C i don't know if i am right
Answer:
Explanation:
The direct reaction of a carboxylic acid with an amine would be expected to be difficult because the basic amine would deprotonate the carboxylic acid to form a highly unreactive carboxylate. However when the ammonium carboxylate salt is heated to a temperature above 100 C water is driven off and an amide is formed.
