Concept explainers
(a)
Interpretation:
Comparison of ratio of atoms or ions in 3p states and in ground state of Na atom and Mg+ is to be done when there is a natural gas air flame of temperature 1800 K.
Concept introduction:
Boltzmann equation is used for the calculation of the ratio. This equation tells that how much an atom or ion is populated as a function of temperature. This equation is given as-
And the calculation of energy of atom and ion is done by the following formula-
Where,
h= Planck’s constant
c = light velocity
λ= wavelength
Ej= energy difference of excited state and ground state
(b)
Interpretation:
Comparison of ratio of atoms or ions in 3p states and in ground state of Na atom and Mg+ is to be done when there is a hydrogen - oxygen flame of 2950K.

(c)
Interpretation:
Comparison of ratio of atoms or ions in 3p states and in ground state of Na atom and Mg+ is to be done when there is an inductively −coupled plasma source of 7250 K.

- Nonearrow_forward4. Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).arrow_forwardThe emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forward
