Hello,

• Describe an experimental procedure that can be used to extract oil from nut seeds.
• In terms of structure and bonding, explain the following observations:

1. The melting point of aluminum is higher than that of sodium.
2. The melting point of chlorine is lower than that of sulphur.

• Describe how a sample of sodium chloride can be prepared in the laboratory by direct synthesis.
