When 26.0 mL of 0.565 M H2SO4 is added to 26.0 mL of 1.13 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate H of this reaction per mole of H2SO4 and KOH reacted. (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for pure water: d = 1.00 g/mL and c = 4.184 J/g×K.) H per mole of H2SO4 reacted: kJ/mol? H per mole of KOH reacted: kJ/mol?
A proton in a linear accelerator has a de Broglie wavelength of 144 pm. what is the speed of the proton?
How many air molecules are in a 13.5 ft x 12 ft x 10ft room? Assume atmospheric pressure of 1 atm, a room temperature of 20.0 degrees Celcius and ideal behavior. There are 28.8 L in 1 cubic foot.
A mixture of CO(g) and O2 (g) in a 1.0-L container at 1.0x10^3 Kelvin has a total pressure of 2.2 atm. After some time the total pressure falls to 1.9 atm as the result of formation of CO2. Find the mass (in grams) of CO2 that forms.
Determine the value of pH of given solutions that are (a) a solution that is 0.40 M CH3CO2H, (b) a 0.40 M CH3CO2H solution, (c) 0.20 M NaCH3CO2. And explain your answer too?
