Just completed the conversion of maleic acid to fumaric acid in the lab using Conc. hcl, heat and recrystallization. question: if the solubilities of the reactant and product were reversed( ie., if product were more soluble) how would one follow the isomerization process? how could one tell when the process was complete
What is the change in air temperature(, assuming the heat from the steam is all absorbed by air)
Imagine a small electron-sensitive probe of volume 1.00pm^3 insterted into an H2+ molecule ion in its ground state. Calculate the probability that it will register the presence of an electron at the following positions
Calculate the ph of a buffer that contains 1.0 M acetic acid and 1.0 M sodium acetate. (ka=1.8x10^-5)
A fishing boat accidentally spills 9 barrels of diesel oil into the ocean. Each barrel contains 42 gallons. If the oil film on the ocean is 2.5 × 10^2 nm thick, how many square meters will the oil slick cover?
A 24.9 mL volume of HCl reacts completely with 55.0 mL of aqueous Na2CO3. The reaction is as follows:2HCl (aq)+ Na2CO3(aq)-> CO2(g)+H2O(l)+2NaCl(aq)
Calculate (a) the work done when the gas expands isothermally against a constant external pressure of 200 Torr until its volume has increased by 3.6 dm3, and (b) the work that would be done if the same expansion had occurred reversibly.
The experimentally measured density under the same conditions is 3.10 g/L. Account for the discrepancy between your calculated value and the experimental result.
A buffer initially contains 0.10 mol acetic acid and 0.13 mol of sodium acetate in 1.00 L. 0.02 mol of potassium hydroxide is added to the buffer
How many grams of acetylene are produced by adding water to 5.0 grams CaC2
The good professor accidently grabs the Na2HPO4 bottle. What pH did professor Whoops expect the solution to be? what was the actual pH of the solution as made
Calculate the vapor pressure of a solution prepared by dissolving 70.0 g of naphthalene, C10H8 (a nonvolatile nonelectrolyte), in 220.0 g of benzene, C6H6, at 20°C. Assume the solution is ideal. The vapor pressure of pure benzene is 74.6 torr at 2..
If 69.5 kJ of heat is applied to a 1034 g block of metal, the temperature of the metal increases by 11.4°C. Calculate the specific heat capacity of the metal in J/g°C.
