Answer: [Kr] 5s1 4d10 silver
[Xe] 6s2 4f14 5d7 Iridium
[Ar] 4s2 3d10 4p4 selenium
[Kr] 5s1 4d4 niobium
[Xe] 6s1 4f14 5d10 gold
[Kr] 5s2 4d10 5p4 tellurium
Explanation:
Selenium and tellurium will have the same properties because they both belong to group 16 in the periodic table.
Silver and gold will have the same properties because they both belong the group 11 in the periodic table.
Elements having the same outermost shell configuration show similar properties since chemical reactions occur by loss or gain of electrons. This loss or gain is determined by the number of electrons occupying the outermost shell. Elements in the same group have the same outermost shell electron configuration and similar properties.
Answer: they have a net positive charge

Ethyl acetate and methyl benzoate combination of reactants will produce ethyl 3-phenyl-3-oxopropanoate when treated first with an alkoxide and then with a diluted aqueous acid
<h3>Ethyl acetate</h3>
One of the most straightforward carboxylate esters is ethyl acetate. The simplest is methyl formate, a former Molecule of the Week. Most people enjoy the taste and aroma of the colorless liquid's sweet, fruity scent.
Ethyl acetate was initially created by combining ethanol and acetic acid, as one might anticipate. The process was the traditional Fischer esterification, which dates back to 1895 and is catalyzed by an acid. This commercial synthesis is still the most popular. A different approach is the Tishchenko reaction, in which acetaldehyde disproportionately reacts with base to form alcohol and acid, which subsequently esterify naturally.
