In a constant-pressure calorimeter 70.0mL of 0.310 M Ba(OH)2 was added to 70.0mL of 0.620 M HCl. The reaction makes the temperature of the solution to increase from 24.04 °C to 28.26 °C. If the solution has the same density as well as specific heat as water, define what is PH for this reaction per mole of H2O produced? Presume that the total volume is the sum of the individual volumes.
the generated hydrogen gas h2 is collected over h2o at the temperature of twenty three degree celsius. the volume of
Calculate the value of ?So in J/K for the combustion of 1 mole of propane to form carbon dioxide and gaseous water. S (C3H8(g)) = 271.3 S (O2(g)) = 203.1 S (CO2(g)) = 212.9 S (H2O(g)) = 188.0
