Topic 4.7 - Types of Chemical Reactions

Front

What is an Acid-Base Neutralization Reaction?

Back

An Acid-Base Neutralization Reaction is a chemical reaction between an acid and a base that produces water and a salt. For example, @@HCl(aq) + NaOH(aq) ightarrow NaCl(aq) + H_2O(l)@@.

Front

What is a Precipitation Reaction?

Back

A Precipitation Reaction occurs when two aqueous solutions react to form an insoluble solid, known as a precipitate. For example, @@AgNO_3(aq) + NaCl(aq) ightarrow AgCl(s) + NaNO_3(aq)@@.

Front

What is a Redox Reaction?

Back

A Redox Reaction involves the transfer of electrons between two species, resulting in changes in oxidation states. For example, @@Fe(s) + CuSO_4(aq) ightarrow FeSO_4(aq) + Cu(s)@@.

Front

What is the general form of a chemical reaction?

Back

A chemical reaction can be represented as: Reactants -> Products. This shows the transformation of substances.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

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 an example of a combustion reaction?

Back

A combustion reaction involves a substance reacting with oxygen to produce heat and light. For example, @@CH_4(g) + 2O_2(g) ightarrow CO_2(g) + 2H_2O(g)@@.

Front

What is a decomposition reaction?

Back

A decomposition reaction occurs when a single compound breaks down into two or more simpler products. For example, @@2H_2O_2(aq) ightarrow 2H_2O(l) + O_2(g)@@.

Front

What is a synthesis reaction?

Back

A synthesis reaction occurs when two or more reactants combine to form a single product. For example, @@2H_2(g) + O_2(g) ightarrow 2H_2O(g)@@.
