A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

Formula for ΔE:

$\Delta E = \sum \text{Bond energy of recatants}- \sum \text{Bond energy of Products}$

$= 6 ( B.E_{C-C}) +12 (B.E_{C-H}) +(B.E_{o \ = \ o}) - 6(B.E_{C-C})-10(B.E_{C-H}) -( B.E_{C=0}) -2(B.E_{0-H})\\\\ = \bold{2 (B.E_{C-H}) +(B.E_{o \ = \ o}) -( B.E_{C=0}) -2(B.E_{0-H})}\\\\$

to calculate the value for ΔE put the value in above formula:

Balance the equation by inserting coefficients as needed. equation: ZnS + HBr -> ZnBr_{2} + H_{2}S ZnS + HBr ⟶ ZnBr 2 + H 2 S

yawa3891 [41]

Answer : The balanced chemical reaction will be,

$ZnS+2HBr\rightarrow ZnBr_2+H_2S$

Explanation :

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

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given chemical reaction is,

$ZnS+HBr\rightarrow ZnBr_2+H_2S$

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

In order to balance the chemical equation, the coefficient '2' put before the $HBr$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$ZnS+2HBr\rightarrow ZnBr_2+H_2S$
