Set of quantum numbers listed in the form: (n,l,ml, ms). for each set of quantum numbers, indentify the corresponding orbital (1s, 2s, 3s....etc) if not allowed say not allowed. a (4, 2, -1, -1/2) b (3, 3, 0, 1/2) c (4, 3, 2, -1/2) d (1, 0, 0, 1/2)
In a 1.0× 10-2 M solution of NH4ClO4(aq), identify the relative molar amounts of these species from Most to Least.
Imagine that you have a 7.00 gas tank and a 4.50 gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
A sample of sodium reacts completely with 0.497 kg of chlorine, forming 819 g of sodium chloride. What mass of sodium reacted
Determine ?H for the formation of one mole of aluminium(III) oxide, Al2O3(s) from the elements?
What mass of melamine, C3N3(NH2)3 will be obtained from 178.5 kg of urea, Co(NH2)2 if the yield overall reaction is 83%
When performing extractions it is often better to do multiple extractions rather than one large volume extraction. suppose you have 100mg of a sample dissolved in 0.6ml of water.
The heat of formation of Al2O3(s) is -1669 kJ/mol. Calculate the heat evolved when .267 g of Al burns in oxygen.
Calculate the mass defect and nuclear binding energy per nucleon of the each of the nuclides indicated below. A)Ti -48 (atomic mass = 47.947947 amu) mass defect = ______amu and Binding energy nucleon = ______MeV/nucleon
The filter is heated to 550 oC, and the filter plus residual then weighs 37.0 g. Another 10.0 L sample of the same water is evaporated, without filtering, yielding a residual mass of 40.0 g.
Water has vapor pressure of 23.8 torr at 25 degrees celsius. Find vapor pressure of water at 40 degrees celsius if delta H of vaporization is 40.7 KJ/mol.
the xylene that received has a density of 0.86 g/ml. Its volume is 2.0 ml, and its concentration is 0.069 g/ml. First of all, need to dilute the solution to a 1:100 ratio (ex: 69000 µg/ml to 690 µg/ml). How do dilute the solution to a 1: 100 ratio..
Which of the following is the correct value for (delta)Go' (delta G naught prime: standard free energy change) for an equilibrium reaction in which 2A + B = C + 3D? The equilibrium concentrations for all chemical species is as follows:
