Sketch a PV diagram and find the work done by the gas during the following stages. (Draw the PV diagram on paper. Your instructor may ask you to turn in this work.)
(a) A gas is expanded from a volume of 1.0 L to 2.6 L at a constant pressure of 3.3 atm.
(b) The gas is then cooled at constant volume until the pressure falls to 2.2 atm.
(c) The gas is then compressed at a constant pressure of 2.2 atm from a volume of 2.6 L to 1.0 L.
(Note: Be careful of signs.)
(d) The gas is heated until its pressure increases from 2.2 atm to 3.3 atm at a constant volume.
(e) Find the net work done during the complete cycle.
Calculate the pH of a 0.047 M solution of carbonic acid H2CO3. The Ka1 of carbonic acid = 2.6 x 10-7 and the Ka2 of carbonic acid = 5.6 x 10-11 what is the easiest way someone can explain this
The NaOH Solution with a concentration of .188M is used to titrate a diprotic acid of unknown concentration. 25.00 mL of the acid solution requires 26.54 mL of NaOH solution. What is the concentration of the acid solution
Calculate the concentration of all species in a 0.100 M phosphorous acid solution. These species include {H3O}, {H2PO3} and {HPO3^2-}. For phosphorous acid, ka1=3.0*10^-2 and Ka2=1.7*10^-7
The solubility of TlCl = 0.29 g in 100 mL at 15.6 o C. Calculate the molar concentration of Tl+ and Cl- in this saturated solution. Calculate Ksp value for TlCl at this temperature.
Dibenzalacetone has two carbon-carbon double bonds. How many geometric isomers are possible? Draw all possible geometric isomers of the product and look up their melting points.
Calculate the ratio of CH3NH2 to CH3NH3Cl required to create a buffer with pH = 10.10 [CH3NH2]/[CH3NH3CL] = ? I know that the answer is 0.34 but is not wright to write it in this way in mastering chemistry and they are errors in the submission
The major reason that antiparallel beta-stranded protein structures are more stable than parallel beta-stranded structures is that
a particular gas exerts a pressure of 785 mmHg. what is this pressure in units of Atmospheres
draw the molecule 1-(4-methoxyphenyl)-2-methylpropan-1-ol. number the carbons on the molecule and identify all the functional groups characterized by the molecules name.
What volume, in liters, of hydrogen gas measured at STP can be produced from 50mL of 6.0 M hydrpbromic acid and ac excess of zinc metal, according to the following reaction: 2HBr(aq)+Zn(s) -> ZnBr2 (aq)+H2(g)
A reaction mixture initially contains 0.86 M NO and 0.86 M S03. Determine the equiibrium pressure of NO2 if Kc for the reaction at this temperature is 0.0118.
Commercial club soda is produced by pressurizing water with 10 atmospheres of CO2. Find the value of KH for CO2 on the net or the library, and calculate how much CO2 is in 12 fl ox. glass of club soda.
