It has been suggested that heating of NaCl in a flame might follow these steps. NaCl(s) NaCl(g)
NaCl (g) → Na(g) + Cl(g)
Na (g) → Na*(g)
Na*(g) → Na(g) + hv (strong yellow line is near 589/590 nm) Na represents an atom of sodium in its ground state, and Na* an atom of sodium in an excited state. The (s) means solid and (g) means gas. The ground-state electron configuration for Na(g) is [Ne]3s' and the electron configuration for Na*(g) is [Ne]3p'.

(a) As the ground-state electron configuration for Na(g) is [Ne]3s', write the ground
electron configuration for Li(g). (1 mark)

(b) From the preceding information and with your answer to Question 2 in mind, the red light emitted by the flame that you observed when LiCl was heated was likely due to
(i) what process (0.5 mark)

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
