Answer:
the earth is tilted towards the sun
Explanation:
In the context, there is a sun and earth system and at a certain point when the earth is moving in its orbit around he sun, some point on the earth experiences the summers season. This is because at this point of the earths revolution, the point on the earth is facing the sun and is also tilted towards the sun. So at this point the sun rays fall directly at the surface. While the place which is tilted away from the sun, experiences winter season.

<span>D.) Oxygen would acquire a stable arrangement of electrons by bonding with two atoms of "Magnesium"
[ As Mg has 2 extra electrons & their size are quite similar ]

Answer:
C, 3.00 moles
Explanation:
First, balance the equation.
4Al + 3O2 ---> 2Al2O3
From the balanced equation, assuming Al is limiting, the mole ratio of Al:Al2O3 = 4:2 = 2:1,
meaning every 2 moles of Al used, produces 1 mole of Al2O3.
So, since 1.5 moles of Al2O3 is produced,
the no. of moles of Al used = 1.5 x2
= 3.0 moles
= C
