calculatorn the past, many students have listed that the accidental addition of too much acetic acid contributed greatly to the

di:erence between the experimental value and the accepted value. Suppose that Student A was supposed to make a 0.18 Msolution by diluting 9.0 mL of 2.0 M acetic acid to 100.0 mL. The expected pH for this solution is 2.74. The Ka of acetic acid is 1.8 x 10-5. a. What would be the expected pH if a Student A accidentally diluted 9.1 mL (instead of 9.0 mL) of the acid to 100 mL.

33 protons 36 electrons 45 neutrons
Artist 52 [7]

As has an atomic number of 33, so it has 33 protons.  

It has a charge of 3-, so there are three more electrons than protons. Thus, there are 36 electrons.  

It has a mass of 75, which is the sum of neutrons and protons.  

33+n=75 ---> n = 75 - 33 = 42 neutrons  

The answer is e) 33 protons, 42 neutrons and 36 electrons.

Upper n subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3 (g). At equilibrium, th
artcher [175]

Answer:

The <u>equilibrium constant</u> is:

              k_c=0.0030M^{-2}

Explanation:

The correct equation is:

  •   N₂(g)    +    3H₂(g)    ⇄    2NH₃(g)

Thus, with the equilibrium concentrations you can calculate the equilibrium constant, Kc.

The equation for the equilibrium constant is:

         k_c=\dfrac{[NH_3]^2}{[N_2]\cdot [H_2]^3}

Substituting:

        k_c=\dfrac{(0.105M)^2}{(1.1M)\cdot (1.50M)^3}

         k_c=0.0030M^{-2}
