Question

Fill in the coefficients that will balance the following reaction: a0Hg(CO3)2 + a1AgCl → a2HgCl4 + a3Ag2CO3

Answer 1

$a_{0}=1 \\ \\ a_{1}=4 \\ \\ a_{2}=1 \\ \\ a_{3}=2$

The explanation is shown in the image attached with

Answer 2

Answer : The value of coefficients are, $a_0=1,a_1=4,a_2=1,a_3=2$ and the balanced chemical reaction will be,

$1Hg(CO_3)_2+4AgCl\rightarrow 1HgCl_4+2Ag_2CO_3$

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

The given unbalanced chemical reaction is,

$a_0Hg(CO_3)_2+a_1AgCl\rightarrow a_2HgCl_4+a_3Ag_2CO_3$

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms are not balanced.

In order to balanced the chemical reaction, the coefficient 4 is put before the $AgCl$ and  the coefficient 2 is put before the $Ag_2CO_3$

That means, the value of coefficients are, $a_0=1,a_1=4,a_2=1,a_3=2$

Thus, the balanced chemical reaction will be,

$1Hg(CO_3)_2+4AgCl\rightarrow 1HgCl_4+2Ag_2CO_3$
