Front

What are coefficients in a chemical equation?

Back

Coefficients are the numbers placed before the compounds in a chemical equation to indicate the number of molecules or moles of each substance involved in the reaction.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat, typically producing carbon dioxide and water.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

Identify the reactants in a chemical equation.

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What is the product of the decomposition of aluminum oxide (Al2O3)?

Back

The products of the decomposition of aluminum oxide are aluminum (Al) and oxygen (O2).

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is important because it reflects the law of conservation of mass, ensuring that matter is neither created nor destroyed in a chemical reaction.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is: Hydrocarbon + O2 → CO2 + H2O.

Front

What are the products of the reaction between calcium and water?

Back

The products of the reaction between calcium (Ca) and water (H2O) are calcium hydroxide (Ca(OH)2) and hydrogen gas (H2).

Front

What is the difference between reactants and products?

Back

Reactants are the substances that undergo a chemical change, while products are the substances formed as a result of the chemical reaction.
