Unit 6: Chemical Equations Grade Replacement

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 does the Law of Conservation of Mass state?

Back

Matter cannot be gained or lost in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds.

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 are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of each substance involved in the reaction.

Front

What is the difference between a balanced and unbalanced equation?

Back

A balanced equation has equal numbers of each type of atom on both sides, while an unbalanced equation does not.

Front

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is: 2H₂ + O₂ → 2H₂O.
