Answer: I have no idea what kind of question this is, but I'm assuming it's a true or false question, and this is true. Although the north-bound pole is south-seeking, a compass would eventually draw you to the North Pole.
Explanation:
The amount in grams of Al₂O₃ produced is approximately 6.80 g.
Aluminium reacts completely with oxygen(air) to produce Al₂O₃. The reaction can be represented with a chemical equation as follows:
AL + O₂ → Al₂O₃
Let's balance it
4AL + 3O₂ → 2Al₂O₃
4 moles of Aluminium reacts with 3 moles of Oxygen molecules to produce 2 moles of Aluminium oxide. Therefore,
Since, aluminium reacts completely, it is the limiting reagent in the reaction. Therefore,
Atomic mass of AL = 27 g
Molar mass of Al₂O₃ = 101.96 g/mol
4(27 g) of AL gives 2(101.96 g) of Al₂O₃
3.6 g of AL will give ?
cross multiply
mass of Al₂O₃ produced = 3.6 × 203.92 / 108 = 734.112 / 108 = 6.797
mass of Al₂O₃ produced = 6.80 g.

Lz=projection of L vector on the direction of the magnetic field
l=-1: theta=135 deg
l=0: theta=90 deg
l=1: theta=45 deg
C. magnetic forces act at a distance
Explanation:
Since he was able to drag the keys along the table by moving the magnet, it shows that magnetic forces acts a distance.
Magnetism is a property exhibited by a wide range of materials.
Around a bar magnet, there are field forces in which the forces of the magnets are felt.
- Magnetic forces are non- contact forces. They don't need to be together to exert their force.
- This is why magnetic forces act at a distance.
