I know this question has multiple parts but I would greatly appreciate some help. Determine the pH during the titration of 27.9 mL of 0.425 M hypochlorous acid (Ka = 3.5×10-8) by 0.401 M KOH at the following points. (a) Before the addition of any KOH (b) After the addition of 7.40 mL of KOH (c) At the half-equivalence point (the titration midpoint) (d) At the equivalence point (e) After the addition of 44.4 mL of KOH
I just dont know if these are right. Any help is much
appreciated!
Compare the size of I and I: I has the same number of protons and more electrons compared to I. For this reason, l'experiences a lower Zeff which makes the ion larger in size compared to l. Question 10 0.15 pts Compare the size of Ca2+ and K+: Ca2+ has more protons and the same number of electrons compared to K+. For this reason, Ca2+ experiences a...
I dont know how to do these so if you can help that would be
great!
In the space below, draw the mechanism for the reaction shown. Be sure to show the movement of all electrons and to draw the structures of any intermediates as well. Using the orbital sketch below, shade the correct lobes to show the three bonding MO_s for (3E) - 1, 3, 5-hexatriene. Be sure to draw a vertical dashed line for each orbital to show...
I know it's a lot, but I would really really appreciate any
help. It is my study guide and I am hoping with your help I can
manage to do good on the exam
