Excess I2 can be used to determine vitamin C levels in solution. Vitamin C (ascorbic acid) reacts in the following manner:
C6H8*6 (aq) + I2 --> C6H6O6 (aq) + 2H^+ (aq) + 2I^- (aq)
If 40.00mL of 0.4445M I2 was added to a sample containing vitamin C, the unused I2, required 23.95mL of .197M S2O3^2- to react. How many moles of vitamin C were originally present?
Suppose that N2 gas may be described as van der waals gas. This gas (n=1.25 mol) is expanded isothermally and reversibly from a volume of 1 liter to 10 liters at 300K
An aqueous solution is 30.0 % by mass ammonia, NH3, and has a density of 0.892 g/mL.The mole fraction of ammonia in the solution is?
An auto mechanic spills 90. mL of 2.6 M H2SO4 solution from a rebuilt auto battery. How many milliliters of 2.5 M NaHCO3 must be poured on the spill to react completely with the sulfuric acid
What is the molarity of sucrose, C12H22O11, that contains 125 g of sucrosein 3.50L of solution?
Calculate the standard emf for each of the following reactions:a)H2(g) + F2(g)---> 2H+(aq) + 2F-(aq)
The Fischer esterification mechanism is examined in the following two questions in the assignment
A molecule can be polar or nonpolar depending upon the nature of the bonds and the shape of the molecule. For a molecule that has different outer atoms the molecular symmetry will decide the polarity.
What is the freezing point of a solution of 1.17 g of 1-naphthol, C10H8O, dissolved in 2.00 mL of benzene at 20°C? The density of benzene at 20°C is 0.876 g/mL. Kf for benzene is 5.12°C/m, and benzene's normal freezing point is 5.53°C.
Use the initial volume of acetic acid, the volume of NaOH required to reach the equivalence point and the value of the molarity of NaOH that you obtained when you standardized this solution against KHP in the strong-acid/strong-base experiment to ..
A copper wire (density = 8.96 g/cm3) has a diameter of 0.39 mm. If a sample of this copper wire has a mass of 43 g, how long is the wire?
35 mL air sample collected at 31 C has a pressure of 575 torr. What pressure will the air exert if it is allowed to expand to 476 mL at 56 ? C? Answer in units of torr.
