Balancing Eq & Chem Rxns REVIEW

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: A + B → AB.

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: AB → A + B.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds. Example: AB + CD → AD + CB.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: Hydrocarbon + O₂ → CO₂ + H₂O.

Front

What are the products of the reaction K + HCl?

Back

The products are KCl + H₂.

Front

What are the products of the reaction Cu + AgNO₃?

Back

The products are Cu(NO₃)₂ + Ag.

Front

What are the products of the reaction C₂H₄ + O₂?

Back

The products are CO₂ + H₂O.

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 mass of the reactants equals the mass of the products.

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, reflecting the law of conservation of mass.
