Law of Conservation of Matter

Front

What is the Law of Conservation of Matter?

Back

Matter is never created or destroyed in a chemical reaction.

Front

If a chemical reaction occurs in a closed system, how does the product mass compare to the reactant mass?

Back

The mass would stay the same.

Front

What happens to the mass of an Oreo cookie when it is crushed into crumbs?

Back

The mass remains the same; it still weighs 20 grams.

Front

If the mass of a chemical reaction's product is 15 grams, what would the mass of the reactants be?

Back

The mass of the reactants would also be 15 grams.

Front

In a chemical reaction, what happens to the atoms of the reactants?

Back

The atoms are rearranged to form products, but the total number of atoms remains the same.

Front

What is an example of a physical change that demonstrates the Law of Conservation of Matter?

Back

Crushing a can; the mass remains the same before and after crushing.

Front

What is a common misconception about the Law of Conservation of Matter?

Back

That matter can be created or destroyed during a chemical reaction.

Front

How does the Law of Conservation of Matter apply to balancing chemical equations?

Back

The number of atoms of each element must be the same on both sides of the equation.

Front

What is the significance of the Law of Conservation of Matter in chemistry?

Back

It helps predict the outcomes of chemical reactions and ensures that mass is conserved.

Front

Can matter change forms (solid, liquid, gas) while still obeying the Law of Conservation of Matter?

Back

Yes, matter can change forms, but the total mass remains constant.
