An analytical chemist is titrating 89.1 mL of a 0.3300 M solution of trimethylamine ((CH3),N) with a 0.7100M solution of HC10. The pK, of trimethylamine is 4.19. Calculate the pH of the base solution after the chemist has added 24.8 mL of the HCIO solution to it. 4 Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HCIO solution added. Round your answer to 2 decimal places. pH = 0 X 5

AHMAD, ASHNA 5 of 35 1 4. 6. 7 A student has two rubber balls of different masses to perform an experiment. Which experiment can the student do to objects? O Roll the rubber balls on thick carpet, and observe if either ball produces a spark. O Move a magnet near each rubber ball, and observe if either ball is attracted to the magnet. O Place the rubber balls ona rough surface, apply a small push, and record the time for each ball to move 30 cm. O Drop the rubber balls at the same time from 5 m, and record the time for each ball to hit the ground. P Type here to search 5.

Consider a barrel containing one copy of each of the 26 letters of the alphabet (A, B, C, …).A. What is the probability of drawing the first three letters of the alphabet (A, B and C) out inexactly alphabetical-order if you replace each letter back in the barrel after you look at it?B. What is the probability of drawing all 26 letters of the alphabet out in exactly alphabeticalorder if you replace each letter back in the barrel after you look at it?C. What is the probability of drawing the first three letters of the alphabet (A, B and C) out inexactly alphabetical-order if you keep the letter out of the barrel after you look at it?

If a solute produces ions when dissolved, it is called an electrolyte because the resulting ions in solution will allow the solution to conduct electricity. A solute that completely dissociates into ions is a stronger electrolyte than one that only partially dissociates into ions. If a solute remains as a molecule when dissolved, it is called a nonelectrolyte.In this tutorial, you will practice identifying substances as strong electrolytes, weak electrolytes, or nonelectrolytes. Part A Each of the following reactions shows a solute dissolved in water. Classify each solute as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. 1. C(1)→C(aq) 2. AB(aq) = A+(aq)+B¯(aq) 3. MN(aq)→M*…
