Question

what is chemical eqauation​

Answer 1

$\bf{Chemical\: Equation :}$ A chemical equation is the symbolic representation of a chemical reaction.

• The equation is also called a word equation.

• The symbols of the reactants and products are always the same.

• Products are always written on the right side in a chemical equation by applying plus sign (+) between the products.

• A chemical equation shows the changes of reactants to the 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.

Examples:

• $\bf{H_2+O_2 \longrightarrow H_2O}$

• $\bf{Zn+H_2SO_4 \longrightarrow +ZnSO_4+H_2}$

The chemical equation can be made more informative by applying symbols :

• Solid - (s)
• Liquid - (l)
• Gases - (g)
• Aqueous solution - (aq)
• Reactants which produce gas in reaction - (↑)
• Reactants which produce solid in reaction - (↓)
