What is a synthesis (combination) reaction?

Back

A synthesis reaction, also known as a combination reaction, occurs when two or more reactants combine to form a single product. The general formula is A + B -> AB.

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. The general formula is 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. The general formula is AB + CD -> AD + CB.

Front

What is the difference between a compound and an element?

Back

A compound is a substance formed when two or more elements chemically bond together, while an element is a pure substance that cannot be broken down into simpler substances.

Front

What is an example of a compound?

Back

An example of a compound is sodium chloride (NaCl), which is formed from the elements sodium (Na) and chlorine (Cl).

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as a reactant in combustion reactions, allowing the fuel (usually a hydrocarbon) to oxidize, releasing energy in the form of heat and light.

Front

What is the product of a complete combustion of a hydrocarbon?

Back

The products of a complete combustion of a hydrocarbon are carbon dioxide (CO2) and water (H2O).
