Question

Why we need to balance a chemical equation? What information is given by balanced chemical equation?

Answer 1

We need balance chemical equation bcoz it is helpful for us to know easily about reaction.. It' gives the new formed product from the react ants...
The Law of conservation of mass of reactant is equal to law of conservation of product is called balanced chemical equation..
Hope it's help u...

Answer 2

$\huge {\underline{\underline{\bf{\pink{ Answer : - }}}}}$

$\large \rm \: (i) \: {\underline {\blue{ \rm{chemical \: equation : - }}}}$

A chemical equation is a symbolic rwpresentation of reaction between elements to form new compounds.

EXAMPLE :- 2H₂ + O₂ --------> 2H₂O

$\large \rm \: (ii) \: {\underline {\orange{ \rm{reason \: for \: balancing \: chemical \: equation : - }}}}$

Chemical equations need to be balanced inorder to satisfy the " Law of conservation of mass " . Law of conversation of mass states that the total mass of reactants should be equal to the total mass of the products .

$\large \rm \: (iii) \: {\underline {\blue{ \rm{examples \: of \: some \: balanced \: chemical \: equations : - }}}}$

• 2HgO ------> 2Hg + O₂

• Zn + 2HCl -------> ZnCl₂ + H₂

• CH₄ + 2O₂ -------> CO₂ + 2H₂O

• C + O₂ ---------> CO₂

• CH₄ + 4Cl₂ ---------> CCl₄ + 4Hcl
