Suppose heat is lost or absorbed by the calorimeter itself would it give a higher or a lower value that the usual value or would this have remained unchanged?
50.0000 g of a compound showed that it contained 12.7520 g C,3.2105 g H, and 34.037 g S. The molecular weight of this compound was determined in a seperate expierment and found to be 94.19u.
Consider following cell. SCE stands for the saturated calomel reference electrode, which has a fixed potential of 0.244 volt. Pt|VOSO4 (0.0184 M), V2(SO4)3 (0.212 M), HClO4 (0.0100 M) || SCE Calculate the cell potential.
Calculate the molality H3PO4 in the solution and Water is the solvent and the molarity of H3PO4 in the solution and the number of ml of the 85% H3PO4 that is required to make 800 ml of 2.00 M H3PO4?
The activity of the antibiotic penicillin slowly decomposes when stored in a buffer at pH 7.0, 298K. The time dependence of the penicillin antibiotic activity
consider the following mechanismab --gt cc --gt dassuming the steady state approximation is valid for c what is the
Sodium carbonate reacts with silver nitrate to produce sodium nitrate and solid silver carbonate
How much time is required to produce 200g of alumimun metal for molten aluminum oxide dissolved in cryolite, if you use a 12.0 amp current.
The mass percent of a three component gas sample is 58.0% C2H4O2, 14.6% NH3 and 27.4% CH2O. Calculate the partial pressure (atm) of CH2O if the total pressure of the sample is 0.340 atm.
Thus the pressure of the components on the left is P where as the pressure on the components on the right is P+Y. To make this clear I will write the chemical potentials as a function of the pressure (eg u1* (P) for the pure solvent on the left)
Acetaldehyde is produced by the dehydrogenation of ethanol according to the following reaction: C2H5OH CH3CHO + H2 An undesired side reaction occurs, which produces ethyl acetate: 2C2H5OH CH3COOC2H5 + 2H2 In a pilot plant, the conversion of ethano..
When the following equation is balanced, H2S + Fe(OH)3 ----> Fe2S3 + H2O the coefficient of H2S is
