The heat of fusion of thallium is 21 j/g, and its heat of vaporation is 795j/g. The melting anf boiling points are 304 degress celcius. The specific heat of liquid thallium is 0.13 j/g*c. how much heat is needed to change 243g of solid thallium at 304 degrees celcius to vapopr at 1457 degrees celcius and 1 atm?
Calculate the specific heat was? Would your computed specific heat be , too low, too high or not affected if you had not dried the metal before placing it into the Styrofoam cup. Explain your answer?
If the gas was not pure butane but 10 mole percent propane and 90 mole percent butane then determine how would the MW value be affected?
What is the theoretical yield and percent yield for this reaction under the given conditions?
I dissolved .5 grams of mustard in 3 mL of distilled water. I was asked to determine the mass percentage of acetic acid in mustard, so I added 2.5 mL of NaOH to turn the mustard solution red.
Find delta H for the solution of one mole of NaOH in H2O If calorimeter constant is 11 cal/deg C
In a coffee-cup calorimeter, 1.40 g of NH4NO3 is mixed with 79.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.23°C.
