Determine the following characteristics of the titration curve for 25.0 mL of 0.400 M NH3(aq) titrated with 0.335 M HI(aq). (For NH3, Kb = 1.8x10-5.) (1a) The initial pH : (1b) The volume of HI(aq) required to reach the equivalence point : (1c) The pH at the half-neutralization point. (1d)The pH at the equivalence point
Saturated acetone vapor enters a heat exchanger at a rate of 8.40 L/s and 1 atm, and emerges from the heat exchanger as a saturated liquid at the same pressure. Water at 1 atm enters the heat exchanger at 10.5 C and at a rate of 9.48 mol/s
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
Mass of nitrogen, Suppose 5.0 liters of Nitrogen (diatomic) is at a temperature of 40 degrees C and a pressure of 1.5 ATM
You take 1 ml of your sample and dialyze it in 1000 ml of buffer. At the end of dialysis what is the concentration of (NH4)2SO4 in your sample. How could you further lower the (NH4)SO4 concentration
What is the concentration of X when the potential is 0.0490 V? Assume that the electrode follows the Nernst equation, the temperature is at 25°C, and that the activity coefficient of X is 1.
An unknown noble gas effuses through a tiny hole into an evacuated space with a rate that is 0.578 times the rate of N2(g): rateunk/raten2=0.578. calculate the molar mass of the noble gas in g/mol using Gtaham's law of effusion (N=14.0)
a)A 10.0 g sample of a mixture of methane (CH4) and ethane (C2H4) reacts with oxygen at 25C and 1 atm to produce carbon dioxide and water (liquid). If the reaction produces 520 kJ of heat, what is the mass percentage of methane in the mixture?
