Chemical reactions and equations
Te explanation is given their with examples
Answer:
✧COMBINATION✧
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.
☆DECOMPOSITION☆
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.
Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
✯SINGLE-REPLACEMENT✯
A single replacement reaction occurs when one element replaces another in a single compound. During the reaction, A replaces B, forming the product compound AC and releasing the less reactive element B.
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O).
✷DOUBLE-REPLACEMENT✷
A double-replacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.
An example is. CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)
✿COMBUSTION✿
Combustion reactions occur when oxygen reacts with another substance and gives off heat and light.
Burning coal, methane gas, and sparklers are all common examples of combustion reactions.
