Phosphorus, Chlorine. The IUPAC name is Phosphorus pentachloride
Answer:
Molarity of Na₂CO₃ = 0.25M
% mass = 2.69
Explanation:
Molarity means mole of solute in 1L of solution
Molar mass of solute (Na₂CO₃) = 105,98 g/m
Moles = mass / molar mass → 6.73 g / 105.98 g/m = 0.0635 m
Mol/L = [M]
0.0635 mol/0.250L = 0.25M
Density of solution = Solution mass / Solution volume
1 g/ml = Solution mass / 250 mL → Solution mass is 250g
% mass will be:
In 250 g of solution we have 6.73 g of solute
in 100 g of solution we have (100 . 6.73)/250 = 2.69
Answer : Ionic compound is created when potassium and chlorine combine. The chemical formula of the compound is KCl.
Explanation :
When potassium and chlorine combine then the type of compound created is Ionic compound.
Ionic compound : These are those compounds which are made of a metal element and non-metal element. Salts are ionic compound which consists of a positive and negative ions.
The electronic configuration of Potassium is,

The electronic configuration of Chlorine is,

From this we conclude that the potassium atom is a metal which has 1 electron in their valence shell and chlorine atom is a non-metal which has 7 electrons in their valence shell. For the complete octet, chlorine atom needs only 1 electron which it receives from the potassium atom.
During this process, potassium atom will loses 1 electron and acquire positive charge and chlorine atom will gain 1 electron from potassium atom and acquire negative charge.

The chemical formula of the compound is KCl.
<h3>The somatic and sex chromosomes mainly differ in their Ploidy.</h3>
- Somatic Chromosomes are Diploid (2n)
- Sex Chromosomes are Haploid (n)
Haploidity of sex chromosomes enables the formation of a diploid zygote after fertilization
<h3>Somatic Chromosomes are homologous in nature while the Sex Chromosomes can be Analogous as in the case of Spermatozoa which bears XY genes </h3>
