If 114 kilo joule is given off per mole of Ethylene reacting, determine how much heat is released when 14.8 kilo grams of Ethylene forms?
Determine the mass of Mg(magnesium,) in reaction with an excess of HCl(hydrochloric acid,) is required to form hydrogen(H2) gas of 128ml ? The Hydrogen gas is collected over H2O(water) at a temperature of twenty five degree celsius and a total pressure =762 mmHg. (The ideal gas law constant R = 0.0821L*atm/K*mol.)
what would you expect to observe if KHCO3 reacted with H2SO4? what test would you perform to identify the product?
what is the differences between partial and full method validation? under what circumstances are they being carried out?
when 2-butanol undergoes E1 dehydration,three alkenes are obtained. Draw the sturctures for these alkenes.Which alkene would you predict to be formed in greatest abundance.
Why are the mobile phases added in order of increasing polarity rather than in the order of decreasing polarity?
A typical frostless refrigerator uses 655 kWh of energy per year in the form of electricity. Suppose that all of this electricity is generated at a power plant that burns coal containing 3.0% sulfur by mass
AgBr is the light-sensitive compound in most photographic films. Assume, when film is exposed, that the light energy absorbed dissociates the molecule into atoms.
