An Atom of the element of Manosium has energy levels 1,2, and 3 with sucessively higher energy. When the atom makes the transition from level 3 to level 1, it emits a photon with wavelength of 500nm. When it makes the transition from level 2 to level 3, it absorbs a photon with a wavelength of 700 nm. What wavelength photon is emitted by the transition from level 2 to level 1?
so far,E=hvE(1to3)=E(1to2)+E(2to3).
Treatment of A with zinc amalgam and HCl affords an optically active, dextrorotatory hydrocarbon C. Identify compounds A, B, and C, including stereochemical configurations. Be sure to explicitly draw H and both wedge/dash bonds at any configuratio..
Water dissolves table salt (NaCl) because: A. NaCl is hydrophobic. B. NaCl has a polar covalent bond. C. water molecules surround the Na and Cl ions due to electric attraction.
Partial pressure of argon = ( ? )atm. Now suppose that 7.00 moles of xenon are added to the vessel without changing the volume or temperature. What is the partial pressure of argon now
What are the proper names for each of the pieces of glassware commonly used in distillation. In distillation, how is a column different than a condenser? How is a fractionating column different than a plain column
An antacid tablet containing magnesium hydroxide as an active ingredient requires 22.6 mL of 0.597 M HCl for complete neutralization. What mass of Mg(OH)2 did the tablet contain?
By what factor (The factor is the ratio of the rates) does the rate of this isomerization reaction increase as the temperature increases from 256 degree celsius to 297 degree celsius ?
When solutions of the compound copper (ii) chloride and zinc nitrate are mixed, does the reaction result to form a precipitate, water, gas, or is there no reaction at all.
At some temperature,a 100-L reaction vessel contains a mixture that is initially 1.00 mol CO and 2.00 mol H2. The vessel also contains a catalyst so that the following equilibrium is attained:
The saturated calomel electrode (S.C.E.) is one commonly used reference electrode, with a potential of 0.242 V versus the S.H.E. Using a table of standard reductions, determine what the potential of each reduction below would be versus the S.C.E.
The Kow for carbon tetrachloride is 220. Using the rule of thumb that log(Koc) = .8*log(Kow), and assuming an organic carbon content of 1% you can estimate the retardation factor for carbon tetrachloride.
