Co-precipitation is the process by which undesirable materials are "carried down" and trapped on the suface or within the desired precitate. The precipitate is washed with distilled water to remove the co-precipitates which are more soluble that the precipitate. Care...
When 50.0 g of iron(3)nitrate, FE(NO3)3, is dissolved in water , the number of nitrate ions present in the solution is
What does this quote mean? Why should the Indian be expected to plant corn, fence lands, build houses, or do anything but get food from day to day, when experience has taught him that the product of his labor will be seized by the white man to-morrow? The most industriou...
What were greenbacks?
Earthquakes are essentially sound waves travelling through the earth. They are called seismic waves. Because the earth is solid, it can support both longitudinal and transverse sismic waves, which travel at different speeds. The speed of longitudinal waves, called P waves, is ...
i got the same answers you got but they are being read a sincorrect in my assignment.
The wave is travelling to the right at 50.0 m/s. What is the amplitude if the maximum displacement is 38.0 cm and the total distance travelled by the wave is 16.0 m. 2) What is the wavelength of the wave? 3)What is the frequency of the wave?
During the combustion of 5.00 g of octane, C8H18, 239.5 kcal is released. a) What is the sign of (delta)H for this reaction? b) How much energy is released by the combustion of 1.00 mol of C8H18
For the process CH4(g) = C(s) + 2H2(g) A reaction is started in a rigid vessel at 1000 K with 1 mole of methane and 1 mole of hydrogen gas at 10 bar. Use table C.3 from your text to determine how many grams of carbon should be formed after the reaction has reached equilibrium.
