The accompanying data were obtained in a slope-ratio investigation of the complex formed between Ni2+and 1-eyclopentene-1-dithiocarboxylie acid (CDA). The measurements were made at 530 nm in 1.00-cm cells.
(a) Determine the formula of the complex. Use linear least-squares to analyze the data.
(b) Find the molar absorptivity of the complex and its uncertainty.
Given the melting point of steel to be approximately 1500C, how much energy is required to melt a cubic inch from room temperature? How much water would this amount of energy raise by 10oC from room temperature?
When the outside temperature is -10°C, a residential heat pump must provide 3.5 x 106 kJ per day to a dwelling to maintain its temperature at 20°C. If electricity costs 8 cents per kWh, determine the minimum theoretical operating cost for each day of..
Direction of a resultant For the given forces, F1, F2, and F3, find the three direction angles aR, ßR, and ?R between the resultant force R123 found in Part B and the x, y, and z axes, respectively. aR, ßR, ?R=?
water in 50 liter rigid container is initially at 500 kpa and 350c. as the result of heat transfer the water obtains
A laminated thick-walled cylinder was fabricated by shrinking a steel (E=200 GPa and nu=0.03) sleeve having an inside diameter of 199.800mm and an outside diameter of 300mm onto a steel tube with an inside diameter of 100mm and an outside diameter of..
Plot the total mass in the tank, in kg, and the amount of heat transfer, in kJ, versus the final quality x ranging from 0.2 to 1.0
.water is the working fluid in a vapor power cycle. the pressure and temperature at the turbine inlet are 1600 psia and
the volume of a cylinder is to be determined from measurements of the diameter and length. if the length and diameter
determine the maximum allowable temperature that will produce a flux of less than 2000 hydrogen atomscm2middots through
A jet of water issues from a nozzle at a speed of 6 m/s and strikes a stationary flat plate oriented normal to the jet, as shown in Figure 1. The exit area of the nozzle is 645 mm2. Ignore friction losses and assume all pressures are atmospheric (zer..
a nozzle receives 0.1 kgs steam at 1 mpa 400oc with negligible kinetic energy. the exit is at 500 kpa 350oc and the
