The mass of a flask is measured when the outside of the flask is wet. However in a previous part of the lab, the outside of the flask is dried before its mass is measured. 1) Will the mass of the vapor in the flask be too high too low, or unaffected? 2) Will the molar mass of vapor in the flask be reported too high, too low, or unaffected?
When 50.0mL of a 1.00M solution of Fe(NO3)3 is mixed with 50.0mL of a 1.00M solution of NaOH a precipitate forms. Determine the mass of the solid produced in this reaction
A chemist dissolves 128 mg of pure hydrobromic acid in enough water to make up of 110 mL solution. Calculate the pH of the solution.
The observed rate constant(k-observed) for one of the trials was measured to be 0.00400 s^-1. If the concentration of hypochlorite was fixed at 0.134 M, calculate the specific rate constant (k) for the trail.
Equal initial pressures of hydrogen and nitrogen are added to a container at 298K where they react as in question 1. (question 1 is at the end) a. If the equilibrium pressure of hydrogen is 1.5 atm, determine the equilibrium pressures of nitrogen a..
the alkyl halide used in the reaction is a primary alkyl halide, and why alkylation does not work at all if a tertiary alkyl halide is used.
Eventually, the amounts of the three species do not change further; the system has reached equilibrium. (at this point, approximately 22% of the HI has decomposed.) Describe what is happening in this system at the molecular level.
Calculate DE, and determine whether the process is endothermic or exothermic for the following cases: q = -142 kJ and w = -530 kJ.
Determine the room temperature heat capacities at constant pressure for the following materials: aluminum, silver, tungston and 70Cu-30Zn brass
The observed melting point of camphor is often low. Look up the molal freezing point depression constant K for camphor and calculate the expected depression of the melting point of a quantity
What is the silver ion concentration in a solution prepared by mixing 353 ml of .357 M silver nitrate with 425 ml of .494 M sodium carbonate?
calculate the mol O2 added in the air, using the fact that the N2 in the ?ue gas equals the N2 added in the air. Then make a carbon balance to obtain the total moles of C added.)
What is the molar solubility of SrSO4 in pure water at 25ºC?
