What is a chemical reaction?

Back

A chemical reaction is a process in which substances (reactants) undergo a transformation to form new substances (products) with different properties.

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, ensuring the law of conservation of mass is followed.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation involves adjusting the coefficients of the reactants and products to ensure that the number of atoms for each element is equal 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 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

How do you identify a chemical reaction?

Back

Signs of a chemical reaction include color change, temperature change, gas production, and the formation of a precipitate.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of each reactant and product involved in the reaction.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

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.
