9- It flows (10 cm') of olive oil during a capillary tube (2 cm in length and (0.04 mm in diameter) If the height of the olive oil in the capillary tube (2.5 cm), calculate the time of the olive oil flow into the capillary tube, if you know that the viscosity of the oil ( ŋ oil = 0.18 N .sec/m? ) density of oil gm (0.918 Cma)?

4. How many collisions/sec will Ar gas have in a cubic container with walls lcm in length at 1 atm pressure and 298K. Assume there are no Ar-Ar collisions. 5. The human ear can detect pressures as low as 2 × 105 Nm-². Given an ear drum area of 1mm?, what is the minimum collision frequency (i.e. collision/sec) the ear can detect for N2 gas at 298K?

Show complete solutions and enclose all final answers in a box. Round off final answers to 4 decimal places and floating values for intermediate answers. Use 2 decimal places for molecular weights.

I need help with 2 and 3 please !

To ensure that you are not confused, I attached what the experiment was about. I highly recommend you read through it before going to the questions. file:///Users/michaelzheng/Downloads/MeasuringEnergy%20(1).pdf

Any chloride anions in solution will combine with the silver cations to produce bright white silver chlorlde precipitate. Suppose an EPA chemist tests a 250. mL sample of groundwater known to be contaminated with copper(II) chloride, which would react with silver nitrate solution like this: CuCl,(aq) + 2 AgNO,(aq)→ 2 AgCl(s) + Cu(NO3),(aq) The chemist adds 44.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He…

A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 360.0 MPa. The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand a force of 6.10 MN. pressure vessel OP W bolts cm side view port Calculate the maximum safe diameter w of the port.
