Not all element names come from english or latin words. the sysmbol for tungsten is W from the german word wolfram. the symbol for mercury is Hg from the greek word hydragyrum. Use the symbols W and Hg to explain the system of symbols for elements.
2,4,6-Trichlorophenol is considerably more acidic (pKa = 6) than phenol. Draw the resonance structures for the 2,4,6-trichlorophenoxide ion that explain why it is more acidic, and provide ONE sentence explaining the significance of these structures..
How would you expect the graph to look if you tried to distill a mixture of pentane and touene. Draw and lable the graph
A 285- flask contains pure helium at a pressure of 750 . A second flask with a volume of 470 contains pure argon at a pressure of 716 .If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of h..
A one mole sample of a monatomic perfect gas with a constant pressure heat capacity of 20.85 J/Kmol is initially at a pressure of 3.25 bar at 200K. It undergoes an adiabatic reversible expansion until its pressure is 1.52 bar.

Is the pH of 100 mL of an aqueous solution containing substantial and approximately equal con- centrations of sodium hydrogensulfite and sodium sulfite closest to a pH of 2, 3, 4, 5, 6, 7, 8, 9, 10, none of these, or cannot be determined
1. what possible precipitate might form by mixing 50.0 ml of 1.010-4 m nacl with 50.0 ml of 1.010-6m agno3? will it
What will be the concentration of all species present, excluding water, when the reaction is at equilibrium?, c) What will be the pH., d) what will be the percent ionization
Ozonolysis of a single enantiomer of R produces S, an acyclic, optically active ketoaldehyde of formula C6H10O2. Propose a structure for compounds Q,R, and S and show how your structures would react appropriately to give these results.
During the synthesis of methyl 3-nitrobenzoate, when the reaction mixture is poured on ice, the product separates out as a solid. Why
which of the following equations represents the proper net ionic equation for the complete neutralization reaction
Calcium carbonate CaCO3 reacts with stomach acid HCL according to the following equation: CaCO3 + HCl --- CaCl2 + H2O + CO2. Tums, antacid, contains CaCO3. If tums is added to 20.0 mL of 4.00M HCl, How many grams of CO2 gas are produced.
