Given Ksp {Fe(OH)2}= 1.6x10-14 and Kb(NH3)=1.8X10-5. What concentration of ammonia is necessary to start to precipitate ferrous hydroxide {Fe(OH)2} from a solution of 0.0030M FeCl2
If 0.130 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
cinnamaldehyde and aniline 2) benzaldehyde and m-nitroaniline 3) benzaldehyde and aniline 4) cyclohexanone and aniline Help would be greatly appreciated and generously ranked
A steam turbine receives a flow of 10,000 lb of steam per hour and delivers 500 kW in that period. Heat losses from the casing and the turbine bearings may be assumed neglible
Compound A (C11H16O) has a band in the IR spectrum at 3450 cm%u20131 (strong, broad) and does not react with pyridinium chlorochromate (PCC) in CH2Cl2
When 4.00g of hydrogen nuclei fuse to form helium in the sun, 0.0265g of matter is converted into energy. Given that the speed of light = 3.00x10^8 m/s and that a jolue = kg*m^2/s^2, calculate how much energy is given off.
