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: 2H₂ + O₂ → 2H₂O.

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a compound breaks down into simpler substances. General formula: 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: Zn + CuSO₄ → ZnSO₄ + Cu.

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: AgNO₃ + NaCl → AgCl + NaNO₃.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light. Example: CH₄ + 2O₂ → CO₂ + 2H₂O.

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides of the equation.

What is the general formula for a single replacement reaction?

Back

The general formula for a single replacement reaction is A + BC → AC + B.

Front

What is the general formula for a double replacement reaction?

Back

The general formula for a double replacement reaction is AB + CD → AD + CB.
