Balancing and Types of Chemical Reactions

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance (usually a hydrocarbon) reacts with oxygen to produce carbon dioxide and water, releasing energy in the form of heat and light.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction, located on the right side of the chemical equation.

Front

What does the Law of Conservation of Matter state?

Back

The Law of Conservation of Matter states that mass is neither created nor destroyed in a chemical reaction; it is conserved.

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 are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change, located on the left side of the chemical 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.

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 the general form of a combustion reaction?

Back

The general form of a combustion reaction is: CxHy + O2 → CO2 + H2O.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy (usually in the form of heat) to the surroundings, while endothermic reactions absorb energy from the surroundings.

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.
