What is the correct name for NO?

Back

Nitrogen Monoxide

Front

Is SF2 polar or non-polar?

Back

SF2 is polar.

Front

Is this molecule polar or non-polar?

Back

The molecule is polar.

Front

Define a polar molecule.

Back

A polar molecule is one that has a net dipole moment due to the presence of polar bonds, resulting in a molecule with a positive and a negative end.

Front

What is a non-polar molecule?

Back

A non-polar molecule is one that does not have a net dipole moment, meaning the charge distribution is even.

Front

Explain the significance of lone pairs in molecular geometry.

Back

Lone pairs can affect the shape of a molecule by repelling bonding pairs, leading to different molecular geometries.

Front

What is the molecular geometry of ammonia (NH3)?

Back

The molecular geometry of ammonia (NH3) is trigonal pyramidal.

Front

What is the difference between a molecular formula and an empirical formula?

Back

A molecular formula shows the actual number of atoms of each element in a molecule, while an empirical formula shows the simplest whole-number ratio of the elements.
