Balancing Equations

The Law of Conservation of Mass states that ________ is neither created or destroyed

• water
• solids
• mass
• volume

All elements and compounds on the LEFT side of the arrow/yields in a chemical reaction are called . .

• Coefficient
• Subscipt
• Reactants
• Product

The small number that represents the number of atoms.

• Reactants
• Product
• Subscript
• Arrow/Yields

All elements and compounds on the RIGHT side of the arrow/yields in a chemical reaction are called...

• Products
• Coefficients
• Subscripts
• Reactants

Represents the reaction has happened.

• Reactants
• Product
• Subscript
• Arrow/Yields

Coefficient is the large number in front of the element or compound that represents the number of molecules.

• true
• false

To balance an equation you must first....

• add a coefficient
• count the number of atoms
• identify the reactants and products in your chemical equation

Steps to balance and equation include

• Identify the Reactants and Products in your chemical equation.
• count the number of atoms for each element for your reactants and products.
• add a coefficient in front of the formula that does not match and adjust your count
• continue adding coefficients to get the same number of atoms of each element on both sides.
• All of the above

When Balancing this equation what are the Coefficients? ___ N2 + ___H2 ---> ___NH3

• 3:9:6
• 1:3:2
• 1:1:1

Law of Conservation of Mass is the same thing as Law of Conservation of_________?

• Momentum
• Force
• Energy
• Law
