Balanced chemical reaction happening here is:
3Mg(s) + N₂(g) → Mg₃N₂(s)
<u>moles of product formed from each reactant:</u>
2.0 mol of N2 (g) x <u> 1 mol Mg₃N₂ </u> = <u>2 mol Mg₃N₂</u>
1 mol N2
and
8.0 mol of Mg(s) x <u> 1 mol Mg₃N₂ </u> = 2.67 mol Mg₃N₂
3 mol Mg
Since N2 is giving the least amount of product(Mg₃N₂) ie. 2 mol Mg₃N₂
N2 is the limiting reactant here and Mg is excess reactant.
Hence mole of product formed here is 2 mol Mg₃N₂
molar mass of Mg₃N₂
= 3 Mg + 2 N
= 101g/mol
mass of product(Mg₃N₂) formed
= moles x Molar mass
= 2 x 101
= 202g Mg₃N₂
<u>202g of product are formed from 2.0 mol of N2(g) and 8.0 mol of Mg(s).</u>

Answer:
A the uneven heating of earths surface
Explanation:
Because earths rotates on its axis, circulating air is deflected torward the right in the northern hemisphere and toward the left Southern Hemisphere. This is called the coriolis effect
In order to get all the amino acids that the body needs to produce proteins, one must eat and drink the necessary food containing amino acids. Amino acids are what comprises proteins thus, in order to obtain the average amount of amino acid, make sure that you have an enough intake of foods rich in proteins.
