(a) The P4,P4,O6,and P4O10 molecules have a common structural feature of four P atoms arranged in a tetrahedron (Figures). Does this mean that the bonding between the P atoms is the same in all these cases? Explain.
(b) Sodium trimetaphosphate (Na3P3O9) and sodium tetrametaphosphate (Na4P4O12) are used as water-softening agents. They contain cyclic P3O93- and P4O124- ions, respectively. Propose reasonable structures for these ions.
A 0.10-cm^3 sample of a solution containing a radioactive nuclide (5.0x10^3 counts per minute per mL) is injected into a rat. Several minutes later 1.0 cm^3 of blood is removed. The blood shows 48 counts per minute of radioactivity. Calculate the ..
It is estimated that more than 5 billion metric tons of CO2 is added to the atmosphere each year. Assume that CO2 is an Ideal gas at 25 oC and 1 atm.
Knowing that two salvage workers had become ill from breathing the fumes, she put on her breathing apparatus as soon as she noticed an overpowering odor like that of vinegar but much more pungent. She entered the building and took a sample of the ..
a solution that was 3.78 x 10-3 m had a transmittance of 0.212 when measured in a 2.00-cm cell. what concentration of x
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable first approximation.)
Zinc metal reacts with hydrochloric acid to produce zinc (II) chloride and hydrogen gas. How many liters of hydrogen gas will be produced at STP when 10.00 g of zinc metal is added to a 30.0 mL of a 0.500 M hydrochloric acid solution
A 20.0 mL sample of 0.150 M KOH is titrated with 0.125 M HClO4 solution. Calculate the pH after the following volumes of acid have been added.
What is the solubility of lead(II) chloride in both hot and cold water? why is the use of hot water critical to the sucess of the experiment
Question 1: Solid ammonium nitrate, NH4NO3 (s), is a crystalline salt commonly used in commercial instant coldpacks, since it gives a highly endothermic heat of dissolution in water (ΔHsoln = +26.4 kJ/mol).
a sample of sodium reacts completely with 0.213 of chlorine forming 351 of sodium chloride. what mass of sodium
Barium sulfate, BaSO4, is so insoluble that it can be swallowed without significant danger, even though Ba2+ ions are toxic. At 25 °C, 1.00 L of water dissolves only 0.00245 g BaSO4. Calculate Ksp for BaSO4.
Select the more polar bond in each of the following pairs: a) C-C or C-O; b) P-Cl or P-Br; c) Si-S or Si-Cl; d) F-Cl or F-Br; e) P-O or P-S.
