Explanation:
Answer:
Explanation:
Given data:
Mass of N₂ = 48.7 g
Moles of N₂ = ?
Molecules of N₂ = ?
Mass of N₂O = ?
Moles of N₂O = ?
Atoms of N₂O = ?
Solution:
Chemical equation:
2N₂ + O₂ → 2N₂O
Number of moles of N₂:
Number of moles = mass/ molar mass
Number of moles = 48.7 g / 28 g/mol
Number of moles = 1.74 mol
Number of molecules of N₂:
1 mole = 6.022 × 10²³ molecules
1.74 mol× 6.022 × 10²³ molecules/1 mol
10.5 × 10²³ molecules
Now we will compare the moles of N₂ with N₂O from balance chemical equation:
N₂ : N₂O
2 : 2
1.74 : 1.74
Moles of N₂O:
1.74 mol
Mass of N₂O:
Mass = number of moles × molar mass
Mass = 1.74 mol × 44 g/mol
Mass = 76.56 g

Explanation:
Ionic crystals
1. They are formed by electrostatic attraction between the cation and anion.
2. Naturally solid and brittle in nature.
3.Generally good conductors of electricity in moltane state and have high melting and boiling points.
Example: NH4Cl is an inonic compound with NH4^+ being cation and Cl- being anion.
Molecular Solid
1. These are formed by sharing of electrons pair between the atoms. A shared pair of e- is called a covalent bond.
2. Usually not a good conductor of electricity even in melted state.
3. They mostly liquids and gases only a few are solids.
examples , CO, CO2 , H2CO3 , etc.
