Answer: ✅
The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure.

Answer:
15moles
Explanation:
Given parameters:
Mass of H₂SO₄ = 1469g
Unknown:
Number of moles = ?
Solution:
To solve this problem, let us first find the molar mass of the given compound;
molar mass = 2(1) + 32 + 4(16) = 98g/mol
So;
Number of moles =
=
Number of moles = 15moles
In No3-1 the oxidation number of oxygen is -5 so oxidation number of N would be +5
