give one example each of decomposition reaction combination reaction displacement reaction and double displacement reaction
Answers
A decomposition reaction occurs when one reactant breaks down into two or more products. ... Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
The reactants, A and B, combine to form a new single product, AB, which is always a compound. An example of a combination reaction is when hydrogen and chlorine react to form hydrochloric acid: The subscripts in the chemical reaction in this image refer to the states of matter.
Single Replacement Reactions. A single replacement reaction occurs when one element replaces another in a single compound. ... An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.
