The vapor pressure of liquid mercury is 0.2729 torr at 100.0 oC and 246.80 torr at 300.0 oC. a.) calculate delta H of vaporization of mercury b.) calculate the normal boiling point of mercury c.) if a mercury thermometer is broken at room temperature, calculate the equilibrium concentration of Hg vapor in ppm in the vicinity of the Hg spill. Compare this value to the OHSA standard for Hg vapor exposure, which is 0.01 ppm I am pretty confident I figured out parts a and b, but I would like someone to answer these to verify and I have no clue how to proceed with part c, so help would be greatly appreciated
How would I calculate the theoretical enthalpy of reaction between HCl + NaOH -> H2O + NaCl
If deep ocean water were stored in the laboratory, how would its pH, its alkalinity concentration and it's CO3^-2 concentration change under the following conditions? 1.) At 5C, 1 atm pressure? 2.) At 20C, 1 atm pressure?
A student made an acetic/acetate buffer by mixing 4.665 g of sodium acetate into 600.00 mL of a 0.0242 M acetic acid solution. What would the pH of the solution be as the result of the addition of 0.0050 mols of hydrochloric acid to the buffer
A 0.1019g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000L of solution. A pipet was used to transfer 10 mL of the solution to a 100 mL volumetric flask. A 2 mL portion of 4 M NaOH (aq) was added to the flask, and th..
Predict the products of the acid-base reaction between acetic acid and methanamine. Draw the molecules or ions and include charges were needed.
How many grams of aspirin were lost in the washing process you used to purify your product, assuming you used 50mL of water for washing? The solubility of aspirin in water is 0.33g per 100mL at room temperature.
