A 44.0 g sample of an unknown metal at 99.0 o C was placed in a constant-pressure calorimeter of negligible heat capacity containing 80.0 mL water at 24.0 o C. The final temperature of the system was found to be 28.4 ...
The reaction of solid dimethylhydrazine ((CH3)2N2H2) and liquefied dinitrogen tetroxide (N2O4) has been investigated as a rocket fuel; the reaction produces gaseous carbon dioxide (CO2) nitrogen (N2) and water vapor (H2O ...
A 0.0500-mol sample of a nutrient substance is burned in a bomb calorimeter containing 2.00 × 10 2 g H 2 O. If the molar mass of this nutrient substance is 114 g/mol, what is the fuel value (in nutritional Cal) if the t ...
Suppose a tank is filled with A2(g) so that initial pressure is 0.8688 atm at temperature of 298K. Some of the A2(g) dissociates and when the system reaches equlibrium the total pressure in the tank is 1.275 atm. Calcula ...
