A sample of chlorine gas in confinedin a 5.9L container at 220. torr and 27 degrees Celsius. How many moles of gas are present in the sample?
The evaporation of water H2O(l) ->H2O(g) is endothermic: Change in T degree +44.01 kJ Determine the minimum mass of water (in ) has to evaporate to absorb 183 joules of heat?
The infrared spectrum of the xanthene reduction product contains evidence that demonstrates that conjugation of the rings is still
In this experiment a hot metal block at 100oC is added to cold water in a calorimeter. The heat lost by the metal block equals the heat gained by the water and the two end up at the same temperature.
A student found that her mixture was 15% NH4Cl and 75% SiO2 .Assuming her calculation are correct, what did she most likely do incorrect in her experiment?
A reaction is preformed in aqueous solution, and the temperature of the solution increases by 15.78 degrees celcius. Is the reaction exothermic or endothermic?
115 mL of H_2O is initially at room temperature 22 0C. A chilled steel rod at 2 0C is placed in the water. If the final temperature of the system is 21.1 0C, what is the mass of the steel bar.
calculate the initial reaction rate when [O3] & [NO] remain essentially constant at the values [O3]0= 7.48 x 10-6 M & [NO]0= 3.26 x 10-5M, owing to continuous production from separate sources.
