What is the chemical formula for Carbon Monoxide?

Back

CO

Front

Is CO2 a polar or non-polar molecule?

Back

Non-polar

Front

Is HCl a polar or non-polar molecule?

Back

Polar

Front

What is the correct Lewis structure for Cl2?

Back

The Lewis structure for Cl2 shows two Cl atoms connected by a single bond, with three lone pairs of electrons on each Cl atom.

Front

What is the chemical formula for Phosphorous Trichloride?

Back

PCl3

Front

Define a polar molecule.

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a distribution of electrical charge.

Front

Define a non-polar molecule.

Back

A non-polar molecule is a molecule that does not have a net dipole moment, meaning the electrical charges are evenly distributed.

Front

What is the significance of the Lewis structure in chemistry?

Back

The Lewis structure represents the arrangement of atoms and the distribution of electrons in a molecule, helping to predict molecular shape and reactivity.

Front

What type of bond is present in HCl?

Back

HCl has a polar covalent bond due to the difference in electronegativity between hydrogen and chlorine.

Front

What is the molecular geometry of PCl3?

Back

The molecular geometry of PCl3 is trigonal pyramidal.
