Answer:
The answer to your question is given below
Explanation:
1. When two hydrogen atoms pair together, they form a single bond to achieve complete duet.
Hydrogen atom has 1 shell and 1 valence electron and they contribute it to form bond, thereby obtaining a stable duet configuration
H + H —> H–H —> H2
2. When two halogen atom pair together, they form a single bond to achieve a complete octet which is stable. For example, Cl has 7 electrons in its outermost shell and need 1 more electron to complete it octet. Each Cl will contribute 1 electron each to form a single bond..
Cl + Cl —> Cl–Cl —>Cl2
3. When two oxygen atoms pair together, they form double bond to achieve a complete octet which is a stable configuration.
Oxygen has 6 electrons in its outermost shell and needs 2 more electrons to complete its octet configuration. Each oxygen atom will contribute 2 electrons each to form a double in order to complete it octet configuration.
O + O —> O=O —>O2
4. When two nitrogen atom pair together, they form a triple bond to achieve a complete octet which is stable. Nitrogen has 5 electrons in its outermost shell and needs 3 more electrons to complete it octet configuration. Each nitrogen atom will contribute 3 electrons each to form a triple bond in order to complete its octet configuration.
N + N —> N≡N —> N2.
Answer : The properties of noble gases which usually occurs in Group 8 A periodic table are described below;
i) They have an outer electrons configuration as
ii) Some elements like Ne and Ar does not form a stable chemical compounds.
iii) They have a large ionization energy, He has the largest ionization energy amongst the group.
<span>CHCl3 because there are more than two atoms in this molecule that are different. Hydrogen has a small electron cloud and occupies less space, where Cl has a larger electron cloud and occupies more space, this would make it different than the expected tetrahedron shape.</span>
Answer:
V is proportional to StartFraction n over p EndFraction.
Explanation:
Let us remind ourselves of the statements of both Boyle's law and Avogadro's laws.
Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Avogadro's law states that at the same temperature and pressure, equal volumes of gases contain equal number of molecules.
Hence ;
V α 1/P (Boyle's law)
V α n (Avogadro's law)
V α n/p (combination of Boyle's law and Avogadro's law)
