In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) <=> HO(g) Use the data below to calculate the value of Kc H2(g) <=> 2 H(g) Kc = 0.00473 1/2 H2(g) + 1/2 O2(g) <=> OH Kc = 0.643
The iron content of an ore can be determined by a redox titration using K2Cr2O7 as the titrant. A sample of the ore is dissolved in concentrated HCl using Sn2+ to speed its dissolution by reducing Fe3+ to Fe2+.
Calculate the molar solubility of iron sulfide in a solution that is saturated with hydrosulfuric acid, H2S ( [H2S] = 0.1 M) and has a pH of 2.0. Ka1 = 8.9 x 10^-8 and Ka2 = 1.2 x 10^-13.
the cathode if you charge a lead storage battery for 1.85 h with a constant current of 13.4 A?
Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B.
That concentration (g / ml) should be prepared with a substance weight of 200g/mol melocular to give an absorbance of 0.8? Assume that the substance has a molar absorbance coefficient of 16,000 and that the cell has a light path length of 1 cm.
Assume that you have a cylinder with a movable piston. What would happen to the gas pressure inside the cylinder if you do the following? Decrease the volume to one third the original volume while holding the temperature constant.
Automobile airbags contain solid sodium azide, NaN3, that reacts to produce nitrogen gas when heated, thus inflating the bag. Calculate the value of w (work) for the following system if 11.8 g of NaN3 reacts completely at 1.00 atm and 22 °C.
