The rate constant for the decomposition of gaseous azomethane, CH3N=NCH3 ? N2 + C2H6 is 40.8 min-1 at a certain temperature. Calculate the number of moles of CH3N=NCH3 that have reacted in a 1.00 L flask 0.0500 min after 4.00 g of CH3N=NCH3 is introduced. The molar mass of azomethane is 58.0824 g/mol.
Why is gravity filtration and not suction filtration used to remove suspended impurities
Most organic polymers are named based on the monomers used in their production. However, poly(vinyl alcohol) (PVA) is not made from vinyl alcohol,
When she introduced 3.63E-2 moles of N2(g) and 6.18E-2 moles of H2(g) into a 1.00 Liter container, she found the equilibrium concentration of NH3(g) to be 9.68E-4 M.
Phosphorus pentachloride decomposes to phosphorus trichloride at high temperatures according to the reaction: PCl5(g) ?PCl3(g) + Cl2(g)
