12/10 Balancing Poll

Front

What is a balanced equation?

Back

A balanced equation has the same number of atoms of each element on both sides of the equation, following the law of conservation of mass.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of a chemical equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of a chemical equation.

Front

How do you determine if a chemical equation is balanced?

Back

Count the number of atoms of each element on both sides of the equation; if they are equal, the equation is balanced.

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a compound in a chemical equation to indicate how many molecules or moles of that compound are involved.

Front

What is a subscript in a chemical formula?

Back

A subscript is a small number written to the right of an element symbol in a chemical formula, indicating the number of atoms of that element in a molecule.

Front

What is the purpose of balancing chemical equations?

Back

The purpose of balancing chemical equations is to ensure that the same number of each type of atom is present on both sides of the equation, reflecting the conservation of mass.

Front

What is a skeleton equation?

Back

A skeleton equation is a chemical equation that shows the reactants and products but not the coefficients needed to balance it.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.
