If Ice melts at 273.15K with delta H fusion equaling 6.01kJ/ mol. An ice cube whose mass is 13.8 kg is dropped in a swimming pool whose temperature is held at 22.5 degrees Celsius.
find calories and joules lost when 75.0 g of water H20 cools from 86.4 degrees celsius to 2.1 degrees celsius.
When 5.00 g of sodium hydroxide (NaOH) was dissolved in 150.00 g of water a value of 10.50oC was obtained for ΔT.
3.5 g of a hydrocarbon fuel is burned in a vessel that contains 250. grams of water initially at 25.00 C. After the combustion, the temperature of the water is 26.55 C.
Calculate the enthalpy of reaction at 490 K. You may assume that the heat capacity is constant, and corresponds to the value at 298 K. You may also assume that there are no phase changes in this system
a student collectedhydrogen gas in a buret by displacing water at 26.0c. the buretcould not be submerged deep enough in
