If the pH probe was miscalibrated and reports the pH and reports the pH to be 1 unit higher than the true pH of the solution it is in, would the molar mass you report for the solid acid be higher than, lower, or equal to the true molar mass of the acid?
How much helium gas would it take to ?ll a gas balloon with a volume of 1020 cm 3 when the temperature is 39.0? C and the atmospheric pressure is 724 mm Hg? Answer in units of mol.
Derive the symmetries of the ligand σ orbitals for an octahedral complex. Draw the MO diagram for Cr(CO)6 showing σ bonding only.
A closed container holds 3.14 mol of C(s) and 12.3 mol of O2(g) at 4.94 atm and -4°C. After the reaction has been run to completion (the only product is CO2(g)).
