In a chemical reaction, the number of atoms in the products will always equal which amount?

the number of atoms in the reactants

half of the number of atoms in the reactants

twice the number of the atoms in the reactants

thrice the number of the atoms in the reactants

What is the Law of Conservation of mass?

Mass is never created or destroyed

Mass is created in a chemical reaction

Mass is created in a physical change

New chemicals formed from a chemical reaction have a larger overall mass than the original reactants

A chemical reaction is balanced when

Both sides have the same number of atoms

both sides have the same elements

What will weigh more when a chemical change is complete? The reactants before the chemical reaction, or the product after the reaction is complete?

The product always weighs more than the reactant

The reactant will weigh more than the product

They both will loose mass after the reaction

What is the Law of Conservation of mass?

Mass is never created or destroyed

Mass is created in a chemical reaction

Mass is created in a physical change

New chemicals formed from a chemical reaction have a larger overall mass than the original reactants

a solid that forms when two liquids are mixed

liquid that forms when two solids are reacted

a gas that forms when vinegar and baking soda react

a change of color in a solution

Mixing baking soda and vinegar causes bubbles of carbon dioxide gas to form. Which of the following statements is true?

A chemical change happened because a new gas was released

A chemical change happened because a color change occurred

A chemical change happened because a precipitate formed

A physical change happened because the vinegar boiled into a gas

Which BEST explains why the total mass of the product(s) would be LESS than the total mass of the reactant(s) after a chemical reaction?

Gases were released into the air during the reaction

Precipitates were created during the reaction

Atoms involved in the reaction lost mass

In any chemical reaction, the total amount of matter before the reaction and the total amount of matter after the reaction must STAY THE SAME according to:

The Law of Conservation of Energy

17. What is a precipitate?

A solid that can be formed by combining two liquids

Which of the following shows ONE example of a physical change and ONE example of a chemical change?
