A 0.1510 gram sample of hydrocarbon produces 0.5008 gram CO2 and 0.128 gram H2O in combustion analysis. Its molecular weight is found to be 106. For this hydrocarbon, determine its empirical formula.
When 0.500 mol of N2O4 gas is placed in a 2.50 L reaction vessel and heated to a set temperature, 65.3% of the N2O4 decomposes. Calculate Kc for the decomposition rxn.
For the following changes, determine if the equilibrium would (L) shift left, (R) shift right, (N) have no effect. H20(g)+C(s) CO(g)+H2(g)
Calculate the number of electrons transferred in the following reaction when it is correctly balanced. C5H8O(g) + O2(g)---> CO2(g) + H2O(l)
Heterogeneous catalysts that perform hydrogenation reactions are subject to poisioning which shuts down their catalytic ability. Compounds of sulfur are often poisons.
A small bubble rises from the bottom of a lake, where the temperature and pressure are 8ºC and 6.4 atm, to the water's surface, where the temperature is 25ºC and pressure is 1.0 atm.
