Answer:
pure covalent bond ( inter atomic bond)
Explanation:
pure covalent exists between atoms of the same kind..two nitrogen atoms have the same electronegativity values hence cancel out making it a pure or non polar covalent bond
Answer:
0 to n − 1
Explanation:
The angular or orbital quantum number, gives a description of the particular subshell or orbital where the electron is found and gives the magnitude of its orbital angular momentum.
The values of the angular momentum quantum number (ℓ) takes on integer values that ranges from 0 to n − 1
Answer:
According to the proton theory of acids and bases by J. Brønsted and T. Lowry, the acid is<u> proton donor</u>.
Explanation:
According to the Bronsted lowry concept an acid is substance that gives protons or hydrogen ion while,
Base is substance that accept hydrogen ion or proton.
Consider the following example:
NH₃ + HCl → NH₄⁺ + Cl⁻
In this example HCl is Bronsted lowry acid it gives H⁺ while ammonia is Bronsted lowry base because it accept H⁺.
This also gives the concept of conjugate acid and base. In given example Cl⁻ is conjugate base of HCl while NH₄⁺ is conjugate acid of ammonia.
Answer:
i - Molality → 0.69 m
ii- 5.1 g of NaNO₃ are required
Explanation:
Our solute is the NaNO₃.
Molality is a sort of concentration, that indicates the moles of solute in 1kg of solvent. (mol/kg)
Molality → moles of solute / kg of solvent
We convert the mass of solvent, from g to kg
17 g . 1kg / 1000 g = 0.017kg
We determine the moles of NaNO₃ → 1 g / 85 g/mol = 0.0117 moles
i - Molality → 0.0117 mol / 0.017 kg = 0.69 m
ii- Molality is 2 m
It means that 2 moles of solute is contained in 1kg of solvent
We convert the mass of solvent from g to kg
30 g . 1kg / 1000 g = 0.030 kg
Molality = mol / mass of solvent (kg) → mol = Molality . mass of solvent(kg)
mol = 2 m . 0.030kg → 0.060 moles
We convert the moles to mass → 0.060 mol . 85 g / 1 mol = 5.1 g of NaNO₃
Answer:
Methane is the bond present
