Types of Reactions and Balancing

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. Example: Ca + O -> CaO.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, producing heat and light. It typically produces carbon dioxide and water. Example: C5H10 + O2 -> CO2 + H2O.

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 precipitate in a chemical reaction?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction. Example: Cu(OH)2(s) in the reaction CuCl2(aq) + NaOH(aq) -> Cu(OH)2(s) + NaCl(aq).

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation by adjusting coefficients. Example: P4 + 3O2 -> 2P2O3.

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 in a chemical reaction that undergo change to form products. Example: In the reaction 2H2 + O2 -> 2H2O, H2 and O2 are the reactants.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction. Example: In the reaction 2H2 + O2 -> 2H2O, H2O is the product.

Front

What is the difference between a single replacement and a double replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound (A + BC -> AC + B). In a double replacement reaction, two compounds exchange components (AB + CD -> AD + CB).
