Question

Diffrance between Combination Reaction and Dcomposition Reaction with examples.​

Answer 1

Answer:

Explanation:

Combination vs Decomposition Reaction

Two or more reactant compounds are involved in combination reactions. A single compound is involved in a decomposition reaction.

Products

Combination reaction results in a single product. Decomposition reactions result in several products.

Half Reactions

In combination reactions, two half reactions have two different starting molecules. In decomposition reactions, a single molecule act as the starting material for both half reactions.

Chemical Bonds

Combination reactions result in bonding of atoms to produce the single end product. In decomposition reactions, chemical bonds are broken down to form two or more end products.

Molecules

Combination reactions cause simple molecules to react and produce complex molecules. Decomposition reactions cause complex molecules to break down into simple molecules.

Answer 2

Answer:

Combination reaction

• One or more reactants combine to from a single product.
• Energy is released
• Elements or compounds may be the reactants.
• Example - An example could be lithium reacting with sulfur to give lithium sulfide.

Decomposition reaction

• A single reactant is decomposed to form one or more products.

• Energy is absorbed.

• Single compound is reactant.
• Example - The breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
