The fertilizer ammonium sulfate [(NH4)2SO4] is prepared by the reaction between ammonia (NH3) and sulfuric acid:
2NH3(g) + H2SO4(aq) -> (NH4)2SO4(aq)
How many kilograms of NH3 are needed to produce 1.00 10^5 kg of (NH4)2SO4?
He diffuses faster than Ar because He is smaller has a higher average speed is less reactive is heavier
Ethane is burned with 20% excess air in a furnace operating at a pressure of 100 kPa. Assume complete combustion occurs. Determine the dew point temperature of the flue gas.
These questions need around a paragraph or two for the answer. For full rating, answer in such manner please. Explain what predictions can you make about the primary structure of an alpha-helical region of a protein that spans a biological membrane
