Types of Chemical Reactions Flashcard Prep

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: Na + Br₂ → NaBr.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a compound breaks down into simpler substances. 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 two compounds exchange ions or bonds to form 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: CH₄ + 2O₂ → CO₂ + 2H₂O.

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a large number placed in front of a chemical formula in a balanced equation to indicate the number of molecules or moles of that substance.

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 the difference between an ionic bond and a covalent bond?

Back

An ionic bond is formed when electrons are transferred from one atom to another, resulting in charged ions. A covalent bond is formed when two atoms share electrons.

Front

What is an example of a balanced chemical equation?

Back

2H₂ + O₂ → 2H₂O is an example of a balanced chemical equation, showing the conservation of mass.

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.
