What are combination and decomposition reactions give examples?

When two or more compounds combine to form one compound, this type of reaction is called a combination reaction. Example: When carbon is burnt in the air, it gives carbon dioxide. When a reactant dissociates to give two or more products, this type of reaction is called decomposition reaction.

Is photosynthesis a combination reaction or decomposition reaction?

Photosynthesis is a combination reaction while respiration is a decomposition reaction.

What is combination reaction and decomposition reaction?

Reactions in which many reactants combine to give one product are called combination reactions whereas, in decomposition one reactant breaks down in many products. Created by Ram Prakash.

What is a real life example of decomposition reaction?

The decomposition reaction has a few applications in the industry and daily life. When a soda bottle is opened, carbonic acid breaks down to produce water and carbon dioxide, which causes the fizz. During the digestion of food in our body, carbohydrates, fats, and proteins decompose to form many simpler substances.

What is combination reaction with example?

When two or more reactants combine with each other to form a new product it is called as combination reaction. Combination reaction is also known as synthesis reaction. For example hydrogen gets combined with chlorine to from hydro-chloride.

What do you understand by combination and decomposition reactions explain with examples is decomposition reaction opposite of a combination reaction?

During the decomposition reaction, a single substance decomposes and form two or many substances. Whereas in combination reaction, two or more reactants combine and form a single substance. Hence, decomposition reaction is called the opposite of combination reaction.

Is respiration a combination or decomposition reaction?

Heat energy is released from cells during respiration. Also, heat is used in breaking up glucose to release energy. Hence, respiration is a thermal decomposition reaction, or more specifically, an exothermic reaction.

Why photosynthesis is called combination reaction?

Answer. The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. The single chemical equation represents the overall process of photosynthesis. …

What is the difference between combination reaction and decomposition reaction write an equation for each type?

Answer. Combination reaction is that reaction in which two or more reactants combine together to form a new single product/compound. Decomposition reaction is that reaction in which a single compound/reactant decomposes to form two or more compounds/products.

What are the examples of combination reaction?

a) Hydrogen reacts with oxygen to form water i.e Combustion of Hydrogen forms Water (do note that this reaction is an exothermic one).

  • b) Hydrogen reacts with chlorine to form Hydrogen chloride(also known as hydrochloric acid)
  • a) Calcium oxide (quick lime) reacts with water to form calcium hydroxide (stalked lime)
  • What are the three types of decomposition reactions with examples?
