Analyzing Chemical Equations

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 do chemical equations use to model chemical reactions?

Back

Chemical formulas.

Front

What must be conserved in a chemical equation?

Back

The same number and type of atoms must be present on both sides of a chemical equation.

Front

What does the arrow in a chemical equation represent?

Back

The arrow indicates the direction of the reaction, showing how reactants are transformed into products.

Front

What is the law of conservation of mass?

Back

The law states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

How do you balance a chemical equation?

Back

By adjusting the coefficients in front of the chemical formulas to ensure the same number of each type of atom on both sides.

Front

What is a reactant in a chemical equation?

Back

A reactant is a substance that undergoes a chemical change in a reaction.

Front

What is a product in a chemical equation?

Back

A product is a substance that is formed as a result of a chemical reaction.

Front

What does the coefficient in a chemical equation indicate?

Back

The coefficient indicates the number of molecules or moles of a substance involved in the reaction.

Front

What is the significance of subscripts in chemical formulas?

Back

Subscripts indicate the number of atoms of each element in a molecule.
