The grams of aluminium extracted from 5000g of alumina is 2647 grams
<h3>Chemical formula of alumina:</h3>
Let's calculate the molecular mass of Al₂O₃
Al₂O₃ = 27 × 2 + 16 × 3 = 54 + 48 = 102 g/mol
Therefore,
102 g of Al₂O₃ = 54 g of aluminium
5000g of Al₂O₃ = ?
mass of aluminium produced = 5000 × 54 / 102
mass of aluminium produced = 270000 / 102
mass of aluminium produced = 2647.05882353
mass of aluminium produced = 2647 grams

A Matter of Degrees: How Does the Tilt of Earth's Axis Affect the Seasons?
The artifact appears to have gone through 2 half-lives.
One half-life for Carbon-14 is 5730 years.
After 5730 years, there would be 1/2 as much carbon-14
After another 5730 years, there would be 1/4 as much carbon-14
The answer is roughly 11,460 years
Yes because they atom with a stable octet electrons is less reactive it does not need any more electrons while an atom that has an partially filled electrons need more electrons to complete octet structure
