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: 2H₂ + O₂ → 2H₂O.

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: 2H₂O → 2H₂ + O₂.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

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

How do you predict the products of a synthesis reaction?

Back

To predict the products of a synthesis reaction, combine the reactants to form a single product, often following the formula of the compounds involved.

Front

What is the general form of a single displacement reaction?

Back

The general form of a single displacement reaction is A + BC → AC + B, where A displaces B in the compound BC.

Front

What is the general form of a double displacement reaction?

Back

The general form of a double displacement reaction is AB + CD → AD + CB, where the ions of two compounds exchange places.

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 a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, ensuring the law of conservation of mass is followed.
