Answer:

(1) It does not suffer from spectral interference, which occurs in flame emission spectroscopy.

(2) By atomic absorption technique, traces of one element can easily be determined in presence of high concentration of other elements.

The technique makes use of the atomic absorption spectrum of a sample in order to assess the concentration of specific analytes within it. It requires standards with known analyte content to establish the relation between the measured absorbance and the analyte concentration and relies therefore on the Beer–Lambert law.

Explanation:

For Mg, (1.2 g Mg/24 g Mg) = 0.05 mol Mg.

For Cl, (3.55 g Cl/35.5 g Cl) = 0.1 mol Cl

So the ratio now is

Mg:Cl = 0.05 : 0.1 = 1:2

I got the 1:2 ratio by dividing both by the smallest number, which is 0.05 mol. Therefore, the empirical for formula of the substance is [tex]MgCl_2[/tex]

The empirical formula of the compound formed when magnesium reacts with chlorine is MgCl₂.

To determine the empirical formula of the compound formed when magnesium (Mg) reacts with chlorine (Cl), we need to find the ratio of the elements in terms of moles.

First, we calculate the number of moles of each element:

Moles of Mg = Mass of Mg / Molar mass of Mg

Moles of Mg = 1.2 g / 24 g/mol

Moles of Mg = 0.05 mol

Moles of Cl = Mass of Cl / Molar mass of Cl

Moles of Cl = 3.55 g / 35.5 g/mol

Moles of Cl = 0.1 mol

Next, we determine the simplest whole-number ratio between the moles of Mg and Cl:

Mg:Cl = 0.05 mol : 0.1 mol

To simplify the ratio, we divide both values by the smaller value (0.05 mol in this case):

Mg:Cl = 0.05 mol / 0.05 mol : 0.1 mol / 0.05 mol

Mg:Cl = 1 : 2

Therefore, the empirical formula of the compound formed when magnesium reacts with chlorine is MgCl₂.

In SO2 and SO3, oxygen combines with sulphur in a fixed ratio.

The law of multiple proportion states that if two elements combine with each other to form more than one chemical compound, then the various masses of the elements which combine with a fixed mass of the other element are in simple multiple ratios.

To illustrate this law, sulphur forms two oxides, SO2 and SO3. The ratio of the oxygen that combines with a fixed mass of sulphur  in the two compounds is 2:3 in accordance to the law of multiple proportion.

Three ways to represent atoms or atomic cations with 11 electrons include :

[tex] {Mg}^{ + } \: {Al}^{2 + } \: {Si}^{3 + } [/tex]

Mg = magnesium has 12 electrons in its neutral state, when it loses one electron to attain stability, it's election becomes 11.

Al = Aluminum has 13 electrons in its neutral state, when it donates 2 electron to attain stability, it becomes (13 - 2). = 11

Si = Silicon has 14 electrons on it's neutral state, when it loses 3 electrons to attain stability, we have (14 - 3) = 11

Hence,

[tex]{Mg}^{ + } \: {Al}^{2 + } \: {Si}^{3 + } [/tex]

are atomic cations with 11 electrons.

Answer:

The mass of Carbon-12 is exactly 12 amu. But, that is not the number that is reported in your periodic table. Carbon as it exists in nature is not all carbon-12. There is some small amount of carbon-13 and even traces of carbon-14 in there. The periodic table reports the average mass of the carbon as it is found in nature, not that of pure carbon-12. The average mass of carbon is slightly heaver than carbon-12, because of the slight amounts of those heaver isotopes of carbon in nature.
