Front

What is the definition of molar mass?

Back

The mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

Define sigma bond.

Back

A sigma bond is a type of covalent bond formed by the direct overlap of atomic orbitals, allowing for free rotation around the bond axis.

Front

Define pi bond.

Back

A pi bond is a type of covalent bond formed by the side-to-side overlap of p orbitals, which restricts rotation around the bond axis.

Front

What is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can form covalent bonds.

Front

What is the shape of the ozone molecule?

Back

The ozone molecule has a bent shape due to the presence of lone pairs on the central atom.
