Balancing Equations

Front

What is a balanced equation?

Back

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

Front

What is the product side of a chemical equation?

Back

The product side is the right side of the equation, which shows the substances formed as a result of the reaction.

Front

How do you identify reactants in a chemical equation?

Back

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

Front

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

Back

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

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of a substance involved in the reaction, helping to balance the equation.

Front

How do you balance the equation Mg + Cl₂ → MgCl₂?

Back

This equation is already balanced as there is 1 Mg and 2 Cl atoms on both sides.

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 many hydrogen atoms are in 3(NH₄)₂CrO₄?

Back

There are 24 hydrogen atoms in 3(NH₄)₂CrO₄.

Front

What does it mean if an equation is unbalanced?

Back

An unbalanced equation has different numbers of atoms for at least one element on each side, indicating that mass is not conserved.

Front

What is a reactant?

Back

A reactant is a substance that is consumed during a chemical reaction.
