Question

Explain balancing chemical equations in 0

Answer 1

The chemical equation needs to bebalanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

Answer 2

$Zn + H_{2}So_{4}\implies ZnSo_{4} + H_{2}$

____________

R | | P |

------------------------

Zn | 1 | Zn | 1

____________

S | 2 | H | 2

______________

O | 1 | S | 1

_______________

O | 4 | O | 4

So, the equation is balanced

Another example -

$Mg + O_{2}\implies MgO$

______________

R | | P |

--------------------------

Mg | 2 | Mg | 2

______________

O | 2 | O | 2

______________

i) $Mg + O_{2}\implies 2MgO$

ii)$2 Mg + O_{2}\implies 2 MgO$

So, the equation is balanced
