Explanation:
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and written along with reactants.
The balanced chemical reaction is:
According to stoichiometry :
2 moles of are produced by absorption of energy = 130 kcal
Thus 12.00 moles of are produced by absorption of energy =
Thus 780 kcal are required to produce 12.00 mol of
Answer:
Explanation:
Hello,
In this case, the dissociation of the given weak acid is:
Therefore, the law of mass action for it turns out:
That in terms of the change due to the reaction extent is:
Thus, by solving with the quadratic equation or solver, we obtain:
Which clearly matches with the hydrogen concentration in the solution, therefore, the pH is:
