Question

Elements of compounds exchange to form two different compounds in which type of reaction?

Answer 1

Answer:

Double Replacement Reaction

Explanation:

There are five different kinds of chemical reaction:

Synthesis reaction: Two or more reactants combine to form one product

General equation: A + B → C

Example: CO₂ + H₂O → H₂CO₃

Decomposition reaction: One compound reacts and breaks down to form two or more compounds or elements.

Genreal equation: A → B + C

Example: 2Al₂O₃ → 4Al + 3O₂

Single replacement reaction: one element reacts to one compound and replaces one element in the compound.

General equation: A + BC → AB + C

Example: Al + Fe₂O₃ → Al₂O₃ + 2Fe

Double replacement reaction: two compounds react and one element of each will replace the other.

Genreal equation: AB + CD → AD + CB

Example: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

Combustion: a fuel (hydrocarbon, for example) reacts with oxygen to form water and carbon dioxide.

Answer 2

Double substitute reaction
