Write the balanced equation for the hydration of CuSO4. Indicate the physical states using the abbreviations (s), (l), or (g) for solid, liquid, or gas, respectively. Use (aq) to indicate the aqueous phase. Indicate appropriate charges on negative and positive ions if they are formed.
Show that the proton condition for a NH4Cl solution is a linear combination of the mass balance equations and the charge balance equation.
Give the structure that corresponds to the following molecular formula and 1H NMR spectrum: C7H12Cl2: ? 1.07 (integral = 6203, s); ? 2.28 (integral = 1402, d, J = 6 Hz); ? 5.77 (integral = 700, t, J = 6 Hz).
when 3.299 of iodine reacts with fluorine, 5.768g of IFx is formed. What is the value of x in product formula (IFx)?"
The electric field at the surface of a charged, solid, copper sphere with radius 0.160m is 3400N/c , directed toward the center of the sphere.
Calculate the work(in kilojoules) done during a synthesis of ammonia(see reaction below) in which the volume contracts from 8.6L to 4.3L at a constant external pressure of 44atm.
Many drugs are high-molecular-weight amines that are weak bases. Such amines are not soluble in water, which limits the ways they can be administered and means that they are not soluble in body fluids such as blood plasma and cerebrospinal fluid
At 0.0oC, if the volume of air is 2.6 mL and the pressure of the atmosphere that day is 815 mmHg, what is the number of moles of air?
Ethylene glycol,C2H4(OH)2, is a colorless liquid used as automobile antifreeze. If the density at 20 degree Celcius of a 4.028m solution of ethylene glycol in water is 1.0241g/mL, What is the molarity of the solution
Experiments have shown that the average frequency of chirping by a snowy tree cricket depends on temperature as shown below.
The volumes of a solution containing 1.10ppm Zn+2 shown in the table below were pipetted into separatory funnels, each containing 5.00mL of an unknown zinc solution. Each was extracted with three 5-mL aliquots of CCl4 containing an excess of 8-hyd..
Determine the rat of consumption of O2 if the initial concentration of NH3 was 0.6719 M and decreased to 0.5827 M after 0.3883 hours
As we discussed in class, we are not necessarily limited to using a minimal basis set. We may write the molecular orbitals as a linear combination of as many atomic orbitals as we wish.
