Answer:
Sodium Chloride has Ionic bond while Hydrogen Chloride has covalent bond.
Explanation:
Na has 11 electrons (2, 8, 1) and need to give away 1 electron to be stable
Cl has 17 electrons ( 2, 8, 7) and needs 1 electron to be stable.
Na transfers 1 electron to CL to form Ionic bond.
While
Hydrogen has 1 electron and shares with Chlorine to be stable.
Covalent bond involves sharing.

Answer:
Mass = 99.8 g
Explanation:
Given data:
Mass of potassium nitride = ?
Mass of nitrogen produced = 10.65 g
Solution:
Chemical equation:
2K₃N→ 6K + N₂
Moles of nitrogen:
Number of moles = mass/ molar mass
Number of moles = 10.65 g / 28 g/mol
Number of moles = 0.38 mol
Now we will compare the moles of nitrogen with potassium nitride.
N₂ ; K₃N
1 : 2
0.38 : 2×0.38 =0.76
Mass of potassium nitride:
Mass = molar mass × number of moles
Mass = 131.3 g/mol × 0.76 mol
Mass = 99.8 g
