Balancing Equations

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products involved.

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 the 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 the equation.

Front

What does the arrow (→) in a chemical equation represent?

Back

The arrow represents the direction of the reaction, indicating that reactants are transformed into products.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is the law of conservation of mass?

Back

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

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

Front

What is the significance of balancing equations?

Back

Balancing equations is crucial to accurately represent the quantities of reactants and products, ensuring compliance with the law of conservation of mass.

Front

What is the product side of a chemical equation?

Back

The product side is the right side of the equation, where the products of the reaction are listed.

Front

How many atoms of oxygen are in the equation 4Al + 3O₂ → 2Al₂O₃?

Back

There are 6 atoms of oxygen on the reactant side (3 O₂) and 6 atoms on the product side (2 Al₂O₃).
