From the Kb values for phosphate below, calculate the
three Ka values of phosphoric acid. Use the correct
subscripts to K.
Similar to above, write the sequence of the three acid
dissociation reactions starting with H3PO4.
Show the matching K-expressions and Ka values next to
each reaction.
Phosphate OH H20 H20 H2000 2.3 x 10 P OH .60 X 10 OH 1.42 x 10
5. Write the acid ionization equations in water of the weak acid H3PO4, and the expressions of K.
5. You have a 5.0 M solution of phosphoric acid, H3PO4 a. Write an equation three dissociation equations. b. As the species becomes more negative, the protons are more attracted to the species. What does this do to acid strength? C. Determine the concentration of all species in solution. Below are the needed ka values. • Ka, = 7.5 x 10-3 • Ka, = 6.2 x 10-8 • Ka, = 4.8 x 10-13 I MacBook 3013
Out of the following acids below that are weak acids, look up the Ka values online. If more than one reactions can occur when the species is placed in water, write out each reaction and assign a Ka to each reaction. Calculate the pKa for each weak acid. 0.5 M HCL 0.5 M HCOOH 0.5 M CH3COOH 0.5 M H2SO4 0.5 M H3PO4 After, calculate the theoretical pH for 0.5 M of each of these acids.
Write two clauses in PROLOG that determines if there are three values in a list that sum up to a value of N. The output should be a single true if there exist three values whose sum is N or a single false if there are not. If there are multiple values whose sum is N then the program should only print true once.
Write a program where you hardcode 4 numerical values for an array. Write a loop to print those values. Another loop to multiply those values by some constant and store them in the original array variable. Print the array values again. ***in Java
My answer(s) were marked as incorrect. My textbook's Ka values
for H3PO4 are: Ka1=7.11x10^-3, Ka2=6.32x10^-8, and
Ka3=4.5x10^-13
What is the pH of the buffer formed by mixing 83.0 mL of 0.280 M Na H2PO4 with (This problem requires values in your textbook's specific appendices, which you can access through the OWLv2 MindTap Reader. You should not use the OWLv2 References' Tables to answer this question as the values will not match.) a. 44.0 mL of 0.470 M HCI? pH =...
1. A) Write down the Plank function (Iv) and list its terms (including numerical values for constants to 4 significant figures). B) Find the maximum of this function. Put it in the form Vmax = AT, where A is a constant, which you should find to 3 significant figures. Note that you will get a transcendental function that you must solve to find Vmax. You will have to interpolate to find the value of A. Construct a table that shows...
(b) List and describe, by numerical examples, the three major rating methods used in property and causality insurance. [60 marks]
5. Write the acid ionization equations in water of the weak acid HiPO, and the expressions of Ka
