Question

In how many ways the chemical reaction can be represented Which are they

Answer 1

Answer:

1. Word equations

• When we represent a chemical reaction in terms of words, we write a         word equation. For example, when hydrogen gas reacts with oxygen gas to form water, we can write a word equation for the reaction as follows:

• hydrogen + oxygen→ water

1. Chemical equations

• When we represent a chemical reaction in terms of chemical formulae (symbols), it is called a chemical equation. The chemical equation for the above reaction would be as follows:  

• 2 $H_{2}$ + $O_{2}$ → 2$H_{2}O$

1. Picture equations

• The same reaction of hydrogen reacting with oxygen, can also be represented in pictures called submicroscopic diagrams. The diagram below shows that the atoms in two hydrogen molecules ($O_{2}$) and one oxygen molecule ($O_{2}$) on the left rearrange to form the two water molecules ($H_{2}O$) on the right of the arrow. Hydrogen atoms are white circles and oxygen atoms are red circles
