Final answer:
Nonpolar covalent bonds form when two atoms of the same element or different elements share electrons equally, resulting in a balanced charge distribution. Examples include Methane (CH4) and molecular oxygen (O2). Another case is the CO2 molecule, which is nonpolar because its polar bond moments cancel out.
Explanation:
This leads to a balanced distribution of charges in the molecule, making it nonpolar. Methane, for instance, consists of a carbon atom that shares four electrons equally with four hydrogen atoms, resulting in a bond where the difference in electronegativity between the carbon and hydrogen atoms is minimal.
Another case is CO₂ where the molecule, though consisting of polar bonds, is overall nonpolar because the geometric layout of the molecule allows for the bond moments to cancel each other out, hence no region of the molecule is more positive or negative than any other. Considering the geometry of the molecule is essential when determining the polarity of a molecule with more than one bond.

insoluble because most Na+1 compounds are insoluble in water
soluble because all S−2 compounds are soluble in water
insoluble because there are no water soluble S−2 compounds
Answers
Answer: Option (a) is the correct answer.
Explanation:
Atomic number of sodium is 11 and its electronic distribution is 2, 8, 1. Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6.
So, when both sodium and sulfur chemically combine together then it results in the formation of an ionic bond due to transfer of an electron from sodium to sulfur atom.
Sodium changes into by losing an electron and sulfur changes into
by gain of two electrons from two sodium atoms.
As it is known that water is a polar solvent and all ionic substances will dissolve in water.
Therefore, we can conclude that when the compound, , is mixed with water, the
is soluble because all
compounds are soluble in water.
When the compound, Na2S, is mixed with water, the Na2S is soluble because all Na+1 compounds are soluble in water. The rest of the choices do not answer the question above.

The Nitric Acid Test
Explanation:
The Nitric Acid Test is used to check if silver is pure or plated. To do so, file a small part of the item in a discreet area where it cannot be seen. Apply a few drops of nitric acid. If the area turns into creamy white, the silver is pure or sterling. If green, it is probably fake or silver-plated.
