Balancing Equations (11/23)

Front

What are reactants in a chemical equation?

Back

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

Front

What does it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved.

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; the total mass of reactants equals the total mass of products.

Front

What are coefficients in a chemical equation?

Back

Coefficients are the numbers placed before the reactants and products in a chemical equation to indicate the number of molecules involved in the reaction.

Front

What are subscripts in a chemical formula?

Back

Subscripts are the small numbers written to the lower right of an element symbol in a chemical formula, indicating the number of atoms of that element in a molecule.

Front

How do you determine if a chemical equation is balanced?

Back

To determine if a chemical equation is balanced, count the number of atoms of each element on both sides of the equation and ensure they are equal.

Front

What is the total mass of products if the total mass of reactants is 12 grams?

Back

According to the law of conservation of mass, the total mass of products will also be 12 grams.

Front

How many atoms of carbon are in C6H12O6?

Back

There are 6 atoms of carbon in C6H12O6.

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products along with their quantities.

Front

What is the difference between a reactant and a product?

Back

Reactants are the starting materials in a chemical reaction, while products are the substances formed as a result of the reaction.
