Molecular polarity has a direct effect on the behavior of molecular compounds. The attractive forces between polar molecules are
Blababa [14]

Answer:

Stronger

Greater

Higher

Explanation:

Molecules are held together by intermolecular forces. These are forces that act between molecules in a particular state matter. Intermolecular forces depend on the nature of the molecule.

For polar molecules, the intermolecular forces are stronger thus it takes more energy to separate them leading to a higher boiling point of polar molecules irrespective of their molecular mass.

If an atom of thorium-234 were to undergo beta emission twice, which atom would result?
AnnZ [28]

Answer:

The answer to your question is  U-234

Explanation:

Data

Thorium-234

beta emission twice

Definition

Beta emission is when a beta particle (electron) is emitted from an atomic nucleus.

First beta emission

                                            ²³⁴₉₀Th   ⇒    ²³⁴₉₁Pa + e⁻

Second beta emission

                                            ²³⁴₉₁ Pa   ⇒  ²³⁴₉₂U  + e⁻

The atom will be Uranium-324

s2008m [1.1K]

Answer:

These substances are called amphiprotic. Water, amino acids, hydrogen carbonate ions, and hydrogen sulfate ions are common examples.

Explanation:

A substance is amphoteric (from Greek amphoteros = "each of two") if it can act as an acid or a base.

For example, aluminum hydroxide is amphoteric because it can act as a base and neutralize strong acids.
