Balancing and Types of Chemical Equations

Front

What is the Law of Conservation of Matter?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total mass of the reactants must equal the total mass of the products.

What happens to the mass of a closed system during a chemical reaction?

Back

The mass remains constant; it does not change before and after the reaction.

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 is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, adhering to the Law of Conservation of Matter.

Front

What type of reaction is represented by the equation: 2 NaBr + Ca(OH)2 → CaBr2 + 2 NaOH?

Back

This is a Double Displacement 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.

Front

What is a Single Replacement reaction?

Back

A Single Replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is a Double Replacement reaction?

Back

A Double Replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

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.
