Back

lowest

Front

Matter includes all of the following except: air, smoke, light, water vapor. Which one is not matter?

Back

Front

The branch of chemistry which studies substances containing carbon is called:

Back

organic chemistry.

Front

What is the correct Lewis structure for Nitrogen?

Back

(Provide the Lewis structure for Nitrogen: N with three dots around it representing its three valence electrons.)

Front

Chemical compounds tend to form so that each atom has an octet (8) of electrons in its highest occupied energy level. This is called the:

Back

Octet Rule.

Front

What is the definition of a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the difference between organic and inorganic chemistry?

Back

Organic chemistry deals with carbon-containing compounds, while inorganic chemistry focuses on compounds that do not primarily contain carbon.

Front

Define the term 'element' in chemistry.

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means.

Front

What is the significance of the octet rule in chemical bonding?

Back

The octet rule states that atoms tend to bond in such a way that they each have eight electrons in their valence shell, leading to greater stability.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
