Answer 1

Answer:

magnesium+Aluminum -- magnelium this metal is used in aircraft bodies and also used as wires

Answer 2

(a) Metal used in making aircraft bodies is Mg-Al .

• A combination of magnesium and aluminium is used to make light aircraft bodies.
• Hence, P is Mg-Al.

 The property of metals to be drawn into thin wires is called as Ductility.

• Metals have a property to drawn into thin wires and it is called as Ductility.

• Hence, R is Ductility.

(b) All ores are minerals but all minerals are not ores because:

• Ores contain multiple impurities along with the metals like, sand, clay particles etc.
• Hence, ores can be minerals.
• For example: Aluminium occurs in multiple forms in earth's crust and one of it's main form is Bauxite.
• But all minerals can't be ores because in minerals we cannot find metals, thereby we can't extract metals from minerals.
