Explanation:
50 mL of 2.0 M of and 25 mL of 2.0 M of
were mixed to make a solution
Final volume of the solution after dilution = 200 mL
Final concentration of
Final concentration of
We use Hasselbach- Henderson equation:
Substituting the values:
Therfore, the pH of the final solution is 7.15
Answer:
Explanation:
For part C, this should be what the graph looks like.
The reactants should have higher energy that the products so that it can release energy. Recall the reaction is N2 + 3H2 => 2NH3 + energy, making it exothermic. Apparently, you are supposed to adjust the energy diagram on the simulation so that 20% of the reactants become the products.
