1. If a chemical cold pack weighing 28grams and at a temperature of -2C was left in a 25C room for 3 days, what would be the final temperature of the pack?
2. I have lab experiment where I was used Styrofoam cup with deionized water for the purpous to mesure temperature of the metal which previously I was boiled for 5min. Instead of Styrofoam cup, suggest a suitable replacement which can be used as a calorimeter?
3. How would the results for atomic weight have differed if the hot water was never brought to a boil?
At 25 degrees Celsius, the reaction: H3O+ + NH3 --> NH+ + OH- is first order in each reactant, and has a rate constant of 4.3x 10^10 M^-1 s^-1
derive the rate equation in terms of [NO] and [O2] as well as k ( Assume N2O2 to be in a steady state )
Octane has a density of 0.692 g/mL at 20 C. How many grams of O_2 are required to burn 1.50 gal of C_8H_18?
A sample of CO2 gas at 795 torr is cooled from 25°C until the new pressure is 125 torr. Calculate the new temperature of the gas.
