What volume o CO gas is produced by the following reaction at 240K and 1 atm pressure? Use ideal gas law for this gas: Ni(CO)4 + Br2 -> NiBr2 + 4CO
The measured % transmittance at the maximum wavelength is 75.3%. A 1.000 mL portion of 0.01000 Cu(II) is then added to the same cell and mixed with the original solution
Radio station KLBJ broadcasts at a frequency of 93.7 × 106 s-1. Determine the length of the waves that corresponds to this frequency.
what is the final temperature of this water/ethanol mixture? (Note: Assume there are no chemical interactions between the water and the ethanol that affect the temperature.)
What is the minimum pressure in kPa that must be applied at 25 °C to obtain pure water by reverse osmosis from water that is 0.156 M in sodium chloride and 0.094 M in magnesium sulfate?
calculate the change in internal energy when 2 moles of CO are converted to 2 moles of CO2 at 1 bar and 25 degrees C
One of the highest concentrations of peroxyacyl nitrates has been found in the Los Angeles (LA) basin at 30 ppb, reaching its peak at mid-afternoon. Most of the pollution in the LA basin is created in an area of only 3000 km^2
Trace amounts of rare elements are found within groundwater and are of interest to geochemists. Europium and terbium are lanthanide-series elements that can be measured from the intensity of their fluorescence emitted when a solution is illuminate..
How much water must be added to 534. mL of 0.180 M HCl to produce a 0.135 M solution? (Assume that the volumes are additive.)
Determine What would be the density of the solid if density of toluene at the temperature of the experiment = 0.864 g/mL.?
A sample of ideal gas at room temperature occupies a volume of 23.0l at a pressure of 232torr . If the pressure changes to 1160torr , with no change in the temperature or moles of gas, what is the new volume,V2 ?
At 700.°C, the total pressure of the system is found to be 3.63 atm. If the equilibrium constant KP is 1.52, calculate the equilibrium partial pressures of CO2 and CO.
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
