Balancing Equations & predicting products koz

Front

What is a balanced chemical equation?

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 during the reaction.

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

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 does the yield sign (→) indicate in a chemical equation?

Back

The yield sign indicates the direction of the reaction, showing that reactants are transformed into products.

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; it is conserved.

Front

What is the 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

How do you balance the equation: CCl₄ + H₂ → CH₃Cl + HCl?

Back

The balanced equation is: CCl₄ + H₂ → CH₃Cl + HCl (1, 1, 1, 1).

Front

What is the first step in balancing a chemical equation?

Back

The first step is to write down the number of atoms of each element present in the reactants and products.

Front

What does it mean if an equation is unbalanced?

Back

An unbalanced equation means that the number of atoms of at least one element is different on the reactant and product sides, violating the law of conservation of mass.
