Predict the relative reaction times with ethanolic AgNO3 for the following compounds and rank them from fastest to slowest: 2-chloro-2-butene, 1-chloro-2-butene, 2-chlorobutane.
consider the following reaction; 3 NO2 + H2O-2HNO3 + NO. what volume of water is needed to produce 2.00 kg of HNO3? (the density of water= 1.00 g/ml). the number of hydrogen atoms in 25 g of C6H1206 is
Using a sample of 350. mL air is collected at 35 Celsius has a pressure of 550. torr. if it is allowed to expand to 425 mL at 57 Celsius then What pressure will the air exert?
how many grams of H2 are needed to react with an excess of N2 and produce 6,867 grams of NH3? the molar mass H2 is 2.016g and the molar mass NH3 is 17.04g
You mix 50 ml of a weak monoprotic acid with 50 ml of NaOH solution in a coffee cup calorimeter. Both solutions and the calorimeter were initially at 22 C.
Calculate qrxn for 1 g of sodium metal, and Delta Hrxn in (KJ ) for the reaction as written. Also, assume the density of water is 1.00g/mL throughout this temperature range and that the loss of H2O is minimal
Apart from the discrete energy values characteristic of a quantum mechanical system, is the result of an invidvidual measurement of the total energy identical to the result obtained on a classical system?
Arrange the following eluents in the increasing order of their eluting power; place the least powerful eluent first: dichloromethane, pentane, water, and methanol.
Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g??C)], that density of water is 1.00 g/mL, and that no heat is lost to the calorimeter itself, nor to the surroundings.
