What is titration? What equation can we use for titration problems? How to determine when to reach the equivalent point? In a potentiometric titration, what is meant by the equivalence point? Suppose that you are going to do a titration experiment to determine the solubility of calcium hydroxide...
What is meant by scale and scope of economy? What is critical or limiting factor in budgeting? Suppose you are trying to classify a variable where 96% of its observations equal 0 and only 4% equal 1. You run a logistic regression, and the classification table shows that 97% o...
Consider the following titration for these three questions: 1.00 L of 4.00 M HNO_3 is titrated with 3.00 M NaOH. 1. How many moles of acid are equal to one equivalent in this titration? Tries 0/45 Consider the titration of 20.00 mL of 0.2672 M ...
A hemoglobin A1c of 7% is equivalent to average blood sugar levels of 160 mg/dl (8.89 mmol/l). Hemogobin A1c of 6% equals, roughly, average blood sugar levels of 130 mg/dl (7.22 mmol/l). But remember, healthy non-diabetics spend most of their day under 100 mg/dl (5.56 mmol/l) ...
Plank had an equation of his own, E = hv, in which E is the energy of a particle of light. The equal sign shows that energy is equivalent to v, which stands for frequency, by a constant factor—a constant known within the equation as h, and as Planck's Constant to a larger ...
They will normally develop a synthetic “equivalent” of effective natural treatments, even though they can never fully duplicate the original or its effectiveness. Barry David Butler October 13, 2013 NOTHING except vegetables, nuts and seeds is appropriate. NO Breads, Rice or Cereals either. ...
I suppose this is for a fanbase with little use for the fact that playing a Tame Impala album loudly in one’s house will produce the audio equivalent of seeing them live. 8. XIU XIU Unclouded Sky Polyvinyl Edition of 1,000 Yet another album that makes me feel like Rowdy Roddy Piper’...
1. Why is phenolphthalein an appropriate indicator for titration of a strong acid with a strong base? Explain based on the pH at the equivalent point and the transition range for phenolphthalein. 2. A Assume that 0.10 M solutions of both acids are titrated with Na...
What equation can we use for titration problems? How to determine when to reach the equivalent point? Explain what is meant by the equivalence point in the titration of HCI solution with NaOH solution. Why is the equation M_AV_A = M_BV_B useful in acid-base titration...
What is the pressure, in kPa, of 420 mm Hg? Explain how to convert 0.550 atm of pressure to its equivalent in kPa. A gas at a pressure of 325 torr exerts a force of (blank) N on an area of 5.5 m2. What is the force exerted?
