Construct a neat and compact table, including title and footnotes if required, to summarise the following information taken from rough notes:
‘Acid A was titrated by four analysts and the following end points were obtained: 20.2mL, 20mL, 21mL and 20.8mL, the conductivities were also measured as 13, 13.6 13.8 and 14.2 micro-siemens respectively. The base used for the titration was 0.1 M sodium hydroxide. Acid B was titrated by four analysts and the following end points were obtained 210.2mL, 200mL, 211mL and 206.8mL, the conductivities were also measured as 12, 12.6 13.0 and 12.2 micro-siemens respectively. The base used for the titration was 0.1 M potassium hydroxide.
Suppose that a 2.00-L metal bottle that contains air at 113K and 2.5 atm pressure is sealed off. If we inject 60.0 mL of liquid helium and allow the entire system to warm to room temperature (25°C), what is the pressure inside the bottle?
The relative electrophoretic mobilities of a 30-kd protein and a 92-kd protein used as standars on an SDS polyacrylamide gel are 0.80 and 0.41, respectively.
a solution is prepared by dissolving 396 grams of sucrose in 624 grams of water. what is the vapor pressure of this solution at 30 degrees celsius.
Which of these given nutrients is likely to limit production if the light supply is adequate and there is no nitrogen fixation?
Calculate the standard free energy change per mole assocatiated with the formation of solid SrSO4. Use the solubility product. Remember G(standard) equals -RTln(K) when all surface effects are neglected.
You have a protein that undergoes conformational change from folded state(F) to unfolded state(U) depending on pH. For each state draw a graph for how scattering intensity might change with time.
ond weighs 44.0 carats. Determine the volume occupied by the diamond, given that its density is 3.5 g/cm3 at 20°C, and that 1 carat = 0.200 g.
what is delta Urxn for the combustion X; the hardware compnent of the calorimeter has a heat capcity of 3.63kj/*c. the specific heat of water is 4.184j/g*c the MW of X is 56.0 g/mol
Considering given equation as P4(s) + 5 O2(g) P4O10(s) where ΔH = -3013 kJ/mol you just need to compute the heat evolved when 436 grams of white Phosphorous (P4)burns in air according to the given equation as above.
Although the planet Venus is similar in size and composition to the Earth, the atmosphere is not conductive to life. The average temperature is about 740 K
Propane reacts with excess oxygen to produce carbon dioxide gas and water. What volume of CO2,measured at 27.2 °C and 0.918 atm, is produced from the reaction of 10.1 g propane with excess oxygen.
