What is Chemical equations ?​

Answer 1

What is Chemical Equation ?

$\huge{\underline{\tt{\green{Answer-}}}}$

A chemical equation is the symbolic representation of a chemical reaction.

The equation is also called word equation.

Symbols of the reactants and products are always same.

A chemical equation shows the changes of reactants to product by an arrow (→) placed between them.

On the LHS of an arrow reactants are written and on the RHS products are written in the chemical equation.

${\underline{\tt{\green{ Balanced \: Chemical \: equation -}}}}$ A balanced chemical equation is that in which the total number of atoms of each element are equal on both side of the equation.

${\underline{\tt{\green{Example-}}}}$

$\sf 6 CO_2 + 6 H_2O \longrightarrow C_6H_12O_6 + 6 O_2$

$\sf Fe_S + 7 O_2 \longrightarrow 2 Fe_2O_3 + 4 SO_2$

$\sf C_O + 17 H_2 \longrightarrow C_8H_18 + 8 H_2O$

${\underline{\tt{\green{ Types \: of \: chemical \: reaction -}}}}$

• Combination reaction
• Decomposition reaction
• Displacement reaction
• Oxidation and Reduction reactions
• Exothermic and Endothermic reactions

Answer 2

Answer:

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. ...

The first chemical equation was diagrammed by Jean Beguin in 1615.
