A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Overall charge is +1

How is it possible for water to be polar but uncharged?

kaheart [24]

Water is polar in that the hydrogen atoms bear a partial positive charge, whereas the oxygen atom bears a partial negative charge, due to the electronegativity of oxygen. ... Water disrupts ionic bonds and hydrogen bonds.

Saponification is a chemical reaction _____. A. due to the presence of a strong organic acid. B. that results in an alcohol and

dezoksy [38]

Answer:

that results in an alcohol and a carboxylic acid.

Explanation:

Saponification is a chemical reaction process of alkaline hydrolysis of esters(R'COOR group) by which soap is obtained.

For Example, when a base such as sodium hydroxide [NaOH] is used to hydrolyze an ester, the products are a carboxylate salt and an alcohol. Because soaps are prepared by the alkaline hydrolysis of fats and oils.

In a saponification reaction, alkaline hydrolysis of fats and oils with sodium hydroxide yields propane-1,2,3-triol and the corresponding sodium salts of the component fatty acids.

i.e Fat or oil + caustic alkali ⇒ Soap + propane-1,2,3-triol

As a specific example, ethyl acetate and NaOH react to form sodium acetate and ethanol:
