What do these isotopes of carbon all have in common?

protons, atomic number, and mass number

What quantities vary between isotopes of an element?

protons, electrons, and atomic mass

protons, electrons, and atomic number

The Law of Conservation of Mass states

that matter cannot be created or destroyed and that the mass of the products must equal the mass of the reactants

that matter exists in all states and reacts the same

that matter can only be changed into new substances by introducing a catalyst

that matter exists in the same state throughout any chemical change

A chemical change is different than a physical change because in a chemical change

A new substance is formed and in a physical change no new substance is formed

Molecules do not physically touch

The change can be seen but in a physical change it cannot

In a chemical reaction

The atoms of the reactants unbond, rearrange, and then rebond to form the products

The atoms of the reactants always stay together to form the products

New atoms are formed which combine to make the products

Some atoms disappear while others multiply to form the products

Which of the following statements is true concerning acids and bases?

acids mixed with bases neutralize each other

acids and bases don't react with each other
