What single condition is required to insure that a molecule will be polar covalent?

Chemistry
1 answer:
KiRa [710]3 years ago
5 0

Answer:

(B) A bond between atoms that are different in electronegativity.

Explanation:

If the atoms have different electronegativities, one atom will have greater electron density than the other. The bond will be polar.

(A) is wrong. Atomic mass does not affect electronegativity.

(C) is wrong. If the two atoms are alike, the bond is pure covalent.

Describe the reason why a reaction between two substances comes to an end.
Shtirlitz [24]

Answer: The process by which a particular substance or different substances are transformed to another is called as Chemical Reaction.One reason, in the case of reversible reactions could be that the reaction reached equilibrium before the reaction was complete.Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.The concentration of reactants decreases as the reaction proceeds and at last their concentration comes to an end. Hence, the reaction stops too. If two reactants are being reacted, then the reactant which is in limited amount will consume first and will result in the termination of reaction.The usual reason is that one (or more) of the reactants gets used up.

Hope that was helpful.Thank you!!!

Nitrogen and hydrogen react to form ammonia according to the following equation: N2(g)+3H2(g)⇌2NH3(g) Consider the following rep
earnstyle [38]

Answer:

The pressure  increases.

Explanation:

According to Avogadro's principle, equal volume of gases contains the same number of moles.  From the reaction equation, there is a decrease in the total number of moles from reactant  to product indicating a decrease in volume (as per Avogadro) and an increase in pressure  according to Boyle's Law-Volume is inversely proportional to  pressure.
