Calculate the mass of silver chloride and dihydrogen monosulfide (H2S) formed when 85.6g of silver sulfide reacts with excess hydrochloric acid.
The equilibrium constant is 100. Calculate the concentrations of O2 present at equilibrium
in the electrolysis of a sodium chloride solution, what volume of H2 is produced in the same time it takes to produce 257L of Cl2, with both volumes measured at 50 celcius degrees and 2.50atm
Which reaction below could not be used to create C-C bonds?
Calcium and Magnesium carbonates occur together in the mineral dolomite. Suppose you heat a sample of the mineral to obtain the oxides,CaO and MgO
If a 484 mL sample of gas at 232 °C is allowed to expand (at constant pressure) to a volume of 494 mL, what will be the new temperature (in °C).
Buffering Action of Proteins, We did this experiment in class but I want to see if the results seem reasonable and, if so, why they were not more varied.
Someday, cars may be powered by clean H2/O2 fuel cells and electric motors. Under standard conditions, such a fuel cell can develop 1.229 volts. If the oxygen is obtained from air (at P=0.21 bar), what pressure of H2 would be required to develop 1..
A calibration curve was prepared from series of standards for various concentrations of this analyte and the line of best fit was determined to be S=1.56C + 0.2, where, S, is the signal in mV and, C, is the concentration in ppm (parts per million)..
Calculate the minimum wavelength of light (in nm) that could break an oxygen-oxygen double bond given that it takes 499 kJ to break on mole of these bonds.
what is the pH of 1.0 L of a buffer that is .11M HNO2 and .150M NaNO2. what is the pH of the buffer after adding 1.0 mL of 12M HCl. pH of original buffer
Write the net ionic equation for each of these reactions and demonstrate how two of them add together to yield the third. Using your data and Hess's Law, determine the enthalphy of ionization of HC2H3O2.
