State all that is implied by the chemical equation 2H2 + O2 ➡2H2O. Give its limitation and their remedies.

All that is implied by the chemical equation 2H₂ + O₂    2H₂O are

It explains that on hydrolysis of water we get hydrogenation and oxygen as a product.

# Molecular mass of H₂ =2 g/mol

# Molecular mass of O₂ =32 g/mol

From the balanced chemical equation, 

2 2=4 g of hydrogen requires 32 g of Oxygen to react completely.

# Limitations of this equation are

1. It doesn't give the conditions required to carry out chemical equation.

2. It doesn't tell whether heat is...

How to balance a reaction by Hit and trial method and by Partial equation method. Explain with some examples. 

Method 1 :

Hit and Trial Method: 

The simplest method to balance a chemical equation is by the hit and trial method. This method is also called trial and error method, or inspection method. In this method, coefficient before the formulae or symbols of the reactants and products are adjusted in such a way that the total number of atoms of each element only both the sides become equal. This is called material balance, or mass balance. In this method first of all, atoms of the element which...

Define chemical reaction. Explain its types and sub-types with example.

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.

Examples :

i. Combustion

ii. Oxidation (rusting

iii. Decomposition or fermentation

iv. Photosynthesis

v. Reacting acids and bases together.
