A metal sample weighing 34.526 g was heated to 98.0 C then quickly transferred into Styrofoam cup calorimeter containing 74.365 g of distilled water at a temperature of 27 C. The temperature of the water in the cup increased and stabilized at 29 C..
If the total mass of the mixture is 452.2 g, what masses of CaCl2 and water should be used?
An oxygen tank kept at 20.0?C contains 28.0 moles of oxygen and the gauge reads 31.0 atm. After two weeks, the gauge reads 20.7 atm. How much oxygen was used during the two-week period?
A saturated solution of Mg(OH)2 is prepared and allowed to equilibriate at 25 degrees celcius. A 25.00 mL sample of the 25 degrees celcius solution is titrated with 0.00508M HCL solution. 1.38 mL of the HCL solution are required to fully react the..
What is the problem of attempting an Adols condensation using different aldehydes
A gas expands and does P-V work on the surroundings equal to 261 J. At the same time, it absorbs 216 J of heat from the surroundings. What is the change in energy of the system?
Determine the ΔH solution for this compound If the heat of solvation for this compound = -30.8 kJ/mol , crystal lattice energy = -62.2 kJ/mol.
A smple of mixture of NaCl, Caco3 and SiO2 weighed 7.30 grams. During the water wash the sample lost 2.21 grams. After treatment with HCL, the sample weighed 2.05 grams.
A chemist needs to determine the concentration of a solution of nitric acid HNO3, She puts 865mL of the acid in a flask along with a few drops of indicator. She then slowly adds 0.600M Ba(OH)2 to the flask until the solution turns pink, indicating..
prepare 100 mL each of five standard solutions: 2.00 x 10-5, 5.00 x 10-5, 1.00 x 10-4, 2.00 x 10-4, and 5.00 x 10-4 M. These will serve as your analytical standards, which means that their phosphate concentrations must be precisely known.
calculate the volume, in liters, occupied by 3.25 moles of Cl2 gas at 1.54 atm pressure and a temperature of 213 degrees celcius?
find out the ΔH rxn for the given reaction as C 3 H 4 (g) + 2 H 2 (g) → C 3 H 8 (g)
