Question

What are combination reactions? Write two equations to explain these reactions.​

Answer 1

Answer:

Write equations for these reactions. Answer: In a combination reaction two or more substances are combined to form new substance while in the decomposition reaction one substance decomposes into two or more substances. Hence, the decomposition reactions are called opposite of combination reactions.

Answer 2

Answer_

Combination Reaction:

A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions are represented by equations of the following form: X + Y → XY. The combination of two or more elements to form one compound is called combination reaction.

• A reaction in which two or more reactants combine to form a single product is known as a combination reaction.
• It takes the form of X + Y → XY
• Combination reaction is also known as a synthesis reaction.
• Example of combination reaction:${\sf{ 2Na \:+ \:}}$ $\sf{Cl}_{2}$ →$\sf{ 2NaCl}$

                                                                :$\sf{C \:+ \:}{{O}_{2}}$ → $\sf{CO}_{2}$
