Chemistry: Change in Temperature in the Production of Silver ChlorideWhen solutions containing silver ions and chloride ions are mixed, silver chloride precipitates:
Ag+(aq) + Cl-(aq) ?AgCl(s) deltaH = -65.5 kJ
Calculate deltaH for the production of 0.200 mol of AgCl by this reaction. Calculate deltaH for the production of 2.50 g of AgCl. Calculate deltaH when 1.500 mmol of AgCl dissolves in water. Please provide detailed explanation.
Determine delta H of this reaction (kJ/mol H 2 SO 4 ) - When 24.4 mL of 0.500M sulphuric acid ,H 2 SO 4 is combined to 24.4ml of 1.00M potassium hydroxide KOH in a coffee cup calorimeter
C6H5OH(s) + 7O2(g) --> 6CO2(g) + 3H2O(g) A 2.000 gram sample of pure phenol, C6H5OH(s), is completely burned according to the equation above.
Determine the percent yield if An 8.50 grams sample of Ammonia gives 12.0 g of Nitric Oxide?
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Prutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin.
How many cubic centimeters of an ore containing only 0.22% gold (by mass) must be processed to obtain $100 worth of gold.
As gas expands from 1.00 L to 2.50 L against constant pressure of 820 torr. Calculate the change in internal energy for the gas, if 120 J of heat is transferred to the gas during the expansion.
A balloon contains 400cm3 of helium at 25degrees and 1atm pressure. If the balloon bursts when the volume exceeds 800cm3. What would be the maximum temperature it could withstand at constant pressure?
what gas are evolved from the acidified solution of hydrolyzed albumin? write equationfor the reaction of the gas with lead II acetate?
By Solving this problem student understand about isotopic abundance and how to calculate atomic weight (average atomic mass) of an element -
calculate the approximate concentration of the solution in mol/kg and determine the volume change of the ballon when it ascends from 1 atm pressure to 240 torr pressure ?
Rank the given solutions in aquous form from lowest to highest boiling point:
2SO2(g) + O2(g) 2SO3(g) Suppose the volume of this system is compressed to one-half its initial volume and then equilibrium is reestablished.
