An amount of 3.50 moles of a perfect gas, initally occupying 20.0L undergoes an irreversible isothermal expansion at 298K in towo steps, until the volume is doubled. Sketch this two-step expansion on P vs V set of axes and label your points. Write any assumptions you make. Calculate the total work of this expansion. If this expansion were reversible, what would the value be?
A water desalination plant is set up near a salt marsh containing water that is 0.10 M NaCl. Calculate the minimum pressure that must be applied at 17°C to purify the water by reverse osmosis.
If it takes 34.0 mL of 0.0250 M K2Cr2O7 to titrate 10.0 mL of a solution containing Fe2+, what is the molar concentration of Fe2+.
How many silver atoms can be produced if 0.00350g of Cu are reacted with excess AgNO3, according to the equation :Cu + 2AgNO3 yields 2Ag + Cu(NO3)2
the absorbance of the solution was found to be .5528. Based on the calibration curve of Y=26.1x + .081 (where absorbance is on y axis and concentration of product C is on the x axis) determine the equilibrium concentration of C, then using an ICE ..
How much heat is required to warm 211 g of ice from -45.9°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
Why do you suppose that the dehydration of cyclohexanol to cyclohexene has been the tradiotional experiment to illustrate the acid-catalyzed dehydration of an alcohol to an alkene?
A single crystal of a metal is oriented for a tensile test such that its slip plane normal makes an angle of 65.5° with the tensile axis. Three possible slip directions make angles of 30°, 48°, and 78° with the same tensile axis.
We do not have a reliable method for determining the number of molar equivalents of bleach being added because commercial preparations vary in concentration and "oxidizing power
Calculate the ratio of HCL molecules in the first excited rotational state to those in the ground state @ 25 C. Assume an equilibrium bond distance of 1.275 angstroms.
Draw a triacylglycerol (triglyceride) made from glycerol, myristic acid [CH3(CH2)12COOH], palmitic acid [CH3(CH2)14COOH], and oleic acid [CH3(CH2)7CH=CH(CH2)7COOH(cis)].
Hydrocarbons are often reacted with steam to form H2, as shown for propane: C3H8(g) + 6 H2O(g) 3 CO2(g) + 10 H2(g) Calculate Kp for this reaction at a particular temperature
