To prevent tank rupture during deep-space travel, an engineering team is studying the effect of temperature on gases confined to small volumes. What is the pressure of 2.20 mol of gas \rm D measured at 251 ^\circ \rm C in a 1.75-\rm L container assuming ideal behavior?
Place the following gases in order of increasing average molecular speed at 300. K: CO, SF6, H2S, Cl2, HBr. (Use the appropriate symbol to separate substances in the list.) chemPadHelp SF6
The Rice-Herzfeld mechanism for the thermal decomposition of acetaldehyde (CH3CO) is the following below (10 points) (1) CH3CHO ---> CH3' + CHO' (k1) (2) CH3' + CH3CHO ---> CH4 + CH2CHO' (k2) (3) CH2CHO' --->CO + CH3' (k3) (4) CH3' + CH3' --->C2H6..
Equilibrium system given: Fe3+(aq) + SCN- (aq) FeSCN2+(aq) Equilibrium system Net ionic equation? What are the net ionic equations for the following
What is the final concentration of (in M) 17.2 mL iron(III) chloride solution with an initial concentration of 0.245 M which is diluted with 16.7 mL of solvent? Assume the volumes are additive.
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.
Esters and amides can be most easily and conveniently prepared by nucleophilic substitution reactions on: (select one or more) alcohols carboxylates acyl chlorides carboxylic acids amines acid anhydrides another amides
determine the final volume of the gas If the gas ocupied 68mL, initally and determine the molarity of the solution
A pentapeptide was found to contain the amino acids Phe, Gly, Met, Ala, and Ser. N-Terminal analysis yielded the PTH derivative of alanine. Partial hydrolysis of the pentapeptide yielded the dipeptides
The volume of a syringe is 0.5 mL and the pressure is 3 atm, when the plunger is at the bottom of the syringe. The syringe is then sealed and forced to the 10 mL mark. What is the pressure inside of the syringe?
Dry air at 1.0 atm is passed over a high voltage electric discharge (~15,000v) to convert 0.85% O2 to O3. The ozonized air is then euilibrated withwater at 25 degrees celcius in a vessel which contains
Assuming the following reaction proceeds in a forward direction Cu2+(aq)+Ca(s)----> Cu(s) + Ca2+(aq) Which one is oxidized and which one is reduced
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0 M AgNO3 solution and a strip of cadmium metal in a 1.0 Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way.
