Answer:

Lithium does form a peroxide as well as an oxide on burning in air and I suspect the low temperature reaction with air forms a significant amount of peroxide.

The tendency of molecules to move toward areas of lower concentration is called _____.

satela [25.4K]

The correct answer is B. The tendency of molecules to move toward areas of lower concentration is called diffusion. This happens when there is a concentration gradient. This is described by the Fick's laws of diffusion. Diffusion is the net movement of molecules from a higher concentration to lower concentration to achieve equilibrium.

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,

$ZnS+HBr\rightarrow ZnBr_2+H_2S$
