Which physical properties of a substance are influenced by the strength of its intermolecular forces?
Bromine is extracted from brine wells. The process involves treating water containing bromine ion with chlorine gas and extracting the Br2 from the solution using an organic solvent. Write a net ionic balanced equation for the reaction of chlorine..
Ozonolysis from unknown compound, A compound, A, c6h8, yields a single organic product, B, upon ozonolysis and absorbs two moles of hydrogen on catalytic hydrogenation to give C.
when carbon is burned in the presence of oxygen, the carbon and oxygen combine to produce carbon dioxide. if you start with 3 grams of carbon and 8 grams of oxygen and they react completely, how many grams of carbon dioxide will be produced?
Oxalic acid is a diprotic acid that occurs naturally in some plants. Calculate the pH and the concentrations of all species present in a 0.36-M solution.
The resultant mixture is then evaporated in a kettle to produce a jam contain- ing 67 wt % soluble solids
Since you need pressure based constant use ideal gas equation (PV=nRT) to convert moles of gas into pressure with units of atmospheres. R=0.0821 L atm/mol K
Why is there a differance in the change in enthalpy and the change in internal engery for the zinc/hydrochloric acid reaction but not for the neutralization reactions
Calculate the change in entropy that occurs when 18.66 g of ice at -14.6°C is placed in 54.05 g of water at 100.0°C in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l)
why glucose had a faster reaction with an unknown sugar oxidase than fructose did based on the structure of both fructose and glucose.
Given the reaction: KMnO4+KI+H2SO4 - - - - - > K2SO4+MnSO4+I2+H2O (unbalanced) How many moles of K2SO4 are produced by allowing five moles each of KMnO4, KI and H2SO4 to react
Use the Frost Circle to draw the energy levels of the Pi molecular orbitals for this ion, show the electronic configuration and explain why the ion is aromatic.
In a particular photoelectron spectrum using 21.21 eV photons, electrons were ejected with kinetic energies of 11.01 eV, 8.23 eV, and 5.22 eV. Sketch the molecular orbital energy level diagram for the species,
