In the following experiment, a coffee-cup calorimeter containing 100 mL of H2O is used. The initial temperature of the calorimeter is 23.0C. If 10.0 g of CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution, Delta Hsol, of CaCl2 is -82.8~kJ/mol.
Use Excel or your favorite spreadsheet program to generate the concentration profiles. You may either estimate the stability parameters using the attached plots or (better) use the attached parameterized forms.
A mass of solid potassium chlorate undergoes thermal decomposition in the presence of a catalyst (manganese dioxide) to produce solid potassium chloride and oxygen gas. As a result, 250mL of oxygen are collected over water at 26.0 degrees C and a ..
What volume (in mL) of 0.657 M solution of iron(III) chloride can be made from 52.3 mL of a 1.89 M solution? Assume the volumes are additive.
A compound of forumula C14H12 gave a positive Baeyer test and burned with a yellow, sooty flame. Treatment with ozone followed by hydrolysis in the presence of zinc gave formaldehyde as one of the products.
What is the boiling point of a mixture composed of 85 g HOCH2CH2OH (ethylene glycol) and 125 g H2O? The boiling point elevation constant for H2O is 0.512 °C/m.
