A chemical reaction in which a single reactant is broken down into two or more products called a decomposition reaction. For example:
CaCO3 -------> CaO + CO2
CuCO3 -------> CuO + CO2
A catalyst is a chemical substance that increases or decreases the rate of a chemical reaction without taking part in a chemical reaction.
The +ve catalyst is the chemical substance that increases the rate of a chemical reaction. For example MnO2. The catalyst is the chemical substance that decreases the rate of a chemical reaction. For example glycerine.
What are valence electrons? What change in the valency observed while moving from left to right in a period?
The electrons present in the outermost shell or valence shell of an atom are called valence electrons.
In a period, valency increases up to the 4th group and decreases up to the 8th group and again increases.
We know, water breaks down into hydrogen and oxygen during its electrolysis. As two elements decompose themselves in this chemical reaction, it is called a decomposition reaction.
2H20 --------> 2H2 + O2
A chemical reaction in which aid and base react together to gee salt and water is called an acid-base reaction.
It is called a neutralization reaction because the acidic and basic nature of compounds is neutralized during the reaction.
