answer and Explanation:

the same amount would have to stay in grams, so if 14 grams of nitrogen is formed, then 8 grams of oxygen, add those two together and you get 22. and that's 22 of the 40 grams used, so 40 su

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

Which colligative property is employed when salt is put on an icy sidewalk to melt ice?
ankoles [38]
<span>The correct answer is 'freezing point depression'. Colligative properties depend on the concentration of molecules of a solute. Examples of other colligative properties are boiling point elevation or vapour pressure lowering. The salt causes ice on the side walk to melt because it lowers the freezing point. </span>
