Front

What is the maximum number of bonds that can be formed by an atom of carbon?

Back

An atom of carbon can form a maximum of 4 bonds.

Front

What does the law of conservation of mass state?

Back

The law of conservation of mass states that in a chemical reaction, atoms and mass are conserved; they are neither created nor destroyed.

Front

What type of bond involves a complete transfer of electrons?

Back

An ionic bond involves a complete transfer of electrons from one atom to another.

Front

What type of reaction involves the combination of a substance with oxygen?

Back

A combustion reaction involves the combination of a substance with oxygen.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

Define covalent bond.

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light.

Front

What is a redox reaction?

Back

A redox reaction is a type of chemical reaction that involves the transfer of electrons between two species, resulting in changes in oxidation states.
