17-10. H2S(aq) is analyzed by titration with coulometrically generated I2 in Reactions 17−3 a and 17−3 b. To 50.00 mL of unknown H2S sample were added 4 g of KI. Electrolysis required 812 s at 52.6 mA. Find the concentration of H2S (μg/mL) in the sample.

A titration is a way to determine the concentration of an unknown base by using an acid with a very accurately known concentration. In a strong acid/strong base titration, the equivalence point is at pH7, and the moles of acid are equal to the moles of base. If 10.351 mL of 0.92547 M H2SO4 were used to bring an unknown concentration of 15 mL of CsOH to a pH of 7.01 , what was the concentration of the CsOH?

Assume the source follower is connected as a buffer amplifier between terminals 1 and 2 of the first figure (instead of the wire shown connecting them originally). The capacitors are large enough to act as short circuits at the frequency of interest. Find a value for RG that makes the AC voltage at the gate vg = 0.8Vgen. Then calculate the buffer amplifier gain VL/vg = AV, using the formula AV = RL/ 1/gm+RL Finally, calculate the buffered lossLB = 20log10(Vgen/VL) with the buffer inserted in the circuit. The value of LB should be considerably smaller than the original L, showing that although source followers have a voltage gain less than 1 , they can prevent significant losses when impedances are mismatched as at the beginning of this problem.

A 30 kg mass is held against a spring of stiffness 600 N/m on a smooth horizontal surface compressing it by an amount d. When the mass is released from rest (from point A ), the spring accelerates it until it reaches its relaxed length, after which the mass moves away from the spring. It then encounters a rough horizontal patch of length 3.25 m (beginning at point B), with a coefficient of kinetic friction of 1/9. After leaving the rough patch (at point C) the mass continues to move horizontally until it reaches x = 0, after which it moves along the smooth vertical surface described by: y(x) = x3 9 (with x and y in m, for x > 0 ). When the mass reaches x = +2.0 m along the cubic curve (labelled point D on the diagram), its speed is measured to be 2.50 m/s. Ignore air resistance throughout this problem, and take g = 10 m/s2 (in −y direction). a) [5] What initial compression d in the spring was required so the mass arrives at point D moving at 2.50 m/s? b) [5] At point D, what is the instantaneous i) magnitude of the normal force the curve exerts on the mass and ii) the mass' rate of change of speed? (Note: Since you've been given the speed at D, parts a and b are completely independent of each other.)
