    Determine if the line through A(1, 2, 3) and B(4, 8, -3) and the line through C(3, 5, 3) and D(0, 2, 4) intersect. Having a hard time figuring out this problem.
  2. Chemistry

    A weak acid with an initial pH of 3.2 was titrated with a strong base. 15 mL of 0.1 M NaOH was added to the acid to reach the equivalence point at a pH of 8.6. What would you expect the approximate pH of the analyte to be after the first 5 mL of 0.1 M NaOH
  3. Chemistry

    What is the pH of a 0.25 M acetic acid solution if the Ka of acetic acid is 1.8 x 10-5? 2.67 0.60 5.34 11.33 I got A, 2.67. I think this is correct as well since acetic acid is a weaker acid and the ph # would make sense.

  2. Vectors

    Also, I think you've got the wrong answer posted. I don't know how you got -1/3, but when I use both equations for the third equation, I get different results.
  3. Vectors

    Does my answer have to be expressed as a point, or just what the parameters are that satisfy the condition that they make both lines intersect?
