What is Avogadro's Law?

Back

What are noble gases?

Back

Noble gases are elements in Group 18 of the periodic table that are generally inert and unreactive due to having a full valence shell of electrons.

Front

How does the Periodic Table organize elements?

Front

What is the formula for calculating pressure in a gas?

Back

The formula is P = F/A, where P is pressure, F is force, and A is area.

Front

What is the significance of the atomic number?

Back

The atomic number of an element is the number of protons in its nucleus and determines the element's identity.

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.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.
