The volume of a liquid varies with temperature according to the following relationship: (³) V = V300K * (0.7 0.75 +3.9 * 10-4 + (²) + + 1.48 * 10-6 where V300K is the liquid's volume at 300K. Calculate the expansion coefficient of this liquid, x, at 320K.

You are going to prepare a silicone polymer, and one of the starting materials is dichlorodimethylsilane, SiCl2(CH3)2. You need its normal boiling point and to measure equilibrium vapor pressures at various temperatures. What is the normal boiling point of dichlorodimethylsilane? Plot these data as ln P versus 1/T At what temperature does the liquid have an equilibrium vapor pressure of 250 mm Hg? At what temperature is it 650 mm Hg? Calculate the molar enthalpy of vaporization for dichlorodimethylsilane using the Clausius–Clapeyron equation.

I have done 5a, b and C.

In the first blank, write the coefficient. You must enter this as a number ("1", not "one"). In the second blank, write the chemical formula. Ignore subscripts. For example, Cu(NO3)2 would be entered "Cu(NO3)2". In the third blank, write the state in the following format: (s), (1), (g), or (aq). Make sure you use parenthesis without any spaces! A solution of potassium sulfite reacts with a solution of nitric acid. potassium reactant + acid other product liquid product gas product 个

Request: Can you please help me with answering the following question? I have provided a diagram to help with the question. Thank you. Question: Given the composition of an iron–carbon alloy containing 0.6 wt% C, at a temperature just below the eutectoid, please specify 1) whether the alloy is hypoeutectoid or hypereutectoid 2) name the proeutectoid phase 3) compute the mass fractions of proeutectoid phase and pearlite 4) make a schematic diagram of the microstructure.

Draw a Pxy diagram for an aqueous solution of NH3. The temperature is such that the vapor pressure of the pure water is 5 kPa and the vapor pressure of pure NH3 is 600 Pa. You need to include the bubble line and the dew 7. line. (a) What is the vapor pressure of the solution when rNH, = 0.6? (b) In which phase the solution will be at P = 4.8 kPa? (c) In which phase the solution will be at P =0.2 kPa? (d) Draw the path for a process that takes a liquid with INH, = 0.6 %3D and P= 4.8 kPa to P= 0.2 kPa.

The molar absorption coefficients of two substances A and B at two wavelengths (denoted 1 and 2) are as follows: εA1, = 7.5 dm3 mol-1, cm-1, ε B1 = 10.0 dm3 mol-1, cm-1, εA2 = 12.0 dm3 mol-1, cm-1, εB2 = 8.0 dm3 mol-1, cm-1, The total absorbances of a solution at these two wavelengths in a cell oflength 5.0 mm were measured as 0.8 and 1.2. respectively. What are the molar concentrations of A and B in the solution?
