Types of Chemical Reactions and Balancing Equations

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. Example: 2H₂ + O₂ → 2H₂O.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting materials in a chemical reaction that undergo change to form products.

Front

What do coefficients represent in a chemical equation?

Back

Coefficients are the numbers placed in front of compounds in a chemical equation to indicate the number of molecules or moles of that 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 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. Example: AB + CD → AD + CB.

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. Example: 2H₂O → 2H₂ + O₂.

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. Example: A + BC → AC + B.

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 is the difference between products and reactants?

Back

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

Front

What is an example of a balanced chemical equation?

Back

An example of a balanced chemical equation is: 2Na + Cl₂ → 2NaCl.
