If pure liquid H2SO4 at 300.15 K (27°C) is added adiabatically to pure liquid water at 300.15 K (27°C) to form a 40 mass-% solution, what is the final temperature of the solution?
If you dropped in a piece of magnesium, the magnesium would disappear and hydrogen gas would be released. Represent this change using symbols for the elements, and write out the balanced equation.
A charge variation with time is given in Figure P1.1.8. Draw the corresponding current variation with time.
Plain carbon steel would be a suitable material for the tanks, but it is essential that the polymer does not become contaminated with iron in storage. Suggest some alternative materials of construction for the tanks.
When dried to remove theremaining water (but not the water of hydration), the final dry Na2S2O2· 5H2O crystals must not contain more than 0.1 %impurity. To meetthis specification, the original solution, before cooling, is further diluted with wate..

The equilibrium constant should vary with temperature according to the relation Kp = ae-b/T use the results of part (b) to determine the values of a and b by a graphical curve-fitting procedure. [Suggestion: Use the spreadsheet program from part (..
Develop the dynamic model for this system as functions of time for any given variation in inputs.
The column will operate at 1.1 bar and ambient temperature. If necessary, the aqueous stream may be recirculated to maintain a suitable wetting rate.
Three waveforms seen on an oscilloscope are shown in Figure P1.4.7. If the horizontal scale is set to 50 ms per division (500 ms for the entire screen width), and the vertical scale is set to 5 mV per division (±25 mV for the entire screen height ..
