Expert Solution & Answer

Explanation of Solution

Advantages of flame atomic absorption spectroscopy over furnace are listed as follows:

1. Relatively inexpensive than graphite.
2. High precision can be obtained.
3. Greater amount of sample can be analyzed.

Advantages of Furnace over flame are listed as follows:

1. Enhanced sensitivity towards concentration of analyte and mass.
2. More efficient atomization.
3. Solution, solid samples and slurries in the range of 5−50 μL can be analyzed.
4. It provides reducing environment for elements that can be readily oxidized.

Disadvantages of flame over furnace are listed as follows:

1. Only solutions are capable to be analyzed in flames.
2. Refractory elements may pose problems.
3. Lesser sensitivity compared to graphite.
4. Large sample of the order 1−2 mL must be added.

Disadvantages of furnace atomic absorption spectroscopy are listed as follows:

1. They involve complexity of instruments that are also quite expensive.
2. They also required predetermined temperatures.
3. It also requires optimization of its automated mechanism for several purposes such as sample drying, atomization, solvent evaporation.
4. Different samples require different operation conditions in furnace. So it requires operator skills.

Identifying the major species in weak acid or weak base equilibria Your answer is incorrect. • Row 2: Your answer is incorrect. • Row 3: Your answer is incorrect. • Row 6: Your answer is incorrect. 0/5 The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HF is a weak acid. acids: HF 0.1 mol of NaOH is added to 1.0 L of a 0.7M HF solution. bases: 0.13 mol of HCl is added to 1.0 L of a solution that is 1.0M in both HF and KF.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it.
