Answer:

Concentration of the solution is 0.376M

Explanation:

Lambert-Beer's law describes the absorbance of a solution that is directely proportional to concentration of the solution, molar absorptivity and path length. The law is:

A = ε×C×l

<em>Where A is absorbance (0.699 for Red Dye #3), ε is molar absorptivity (1.217L mol⁻¹cm⁻¹), C is concentration of solution and l is path length (1.526cm)</em>

Replacing:

0.699 = 1.217L mol⁻¹cm⁻¹×C×1.526cm

C = 0.3764 mol/L

<em>Concentration of the solution is 0.376M</em>

Nitrogen and hydrogen combine to form ammonia.
zhenek [66]

The balanced chemical equation for the formation ammonia is

    N2(g) + 3H2(g)  ----> 2NH3(g)  .        

The balanced chemical equations explains that the same number of each element exist as reactants and products.  The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.

For the formation of ammonia, the chemical equation is

     N2(g) + H2(g)  ----> NH3(g)

Balancing the chemical reaction, we can write,

  N2(g) + 3H2(g)  ----> 2NH3(g)  .  

This equation shows two nitrogen entering the reaction together and two hydrogens entering the reaction together. Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogen and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3. This is the balanced chemical reaction.
