So the unbalanced equation would be Mg + N^2 --> Mg^3N^2
Which means the balanced equation would be 3Mg + N^2 --> Mg^3N^2
This is balance the equation out since you now has 3 magnesium and 2 nitrogen on the left side, and 3 magnesium on 2 nitrogen on the right. Double check my work though, it's been awhile.
You would need exactly 50 molecules of glucose.
Thermohaline circulation that occur in the ocean part that flows across sea surface help to supply heat to polar regions.
<h3>What is Thermohaline circulation?</h3>
The thermohaline circulation refer to a section and region of the ocean circulation which is majorly driven by heat gradient and freshwater that flows across the sea surface and also from the mixture of heat and salt that occur at the inside part of the ocean.
Therefore, Thermohaline circulation help to supply heat to polar regions.

Covalent bond is the type of bond which involves the sharing of valence electrons between two atoms.
This bond usually arises from the equal attraction of the nuclei of the two atoms for the electrons shared.
Ionic bond, on the other hand, arises due to the transfer of electrons from the valence shell of one atom to the valence shell of the other.
27.7g
Explanation:
Given parameters:
Number of moles of oxygen = 3.15moles
Unknown:
Mass of reacting propane = ?
Solution:
Equation of the reaction:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We work from the known to the unknown parameters.
The known in this expression is the number of moles of oxygen.
In the reaction:
5 moles of oxygen gas reacts with 1 mole of propane
3.15 mole of oxgen gas will react with 
= 0.63moles
Number of moles of reacting propane gas is 0.63moles
To find the mass;
mass = number of moles x molar mass = 0.63 x molar mass
molar mass of propane = (3 x 12) + (8x1) = 44g/mol
mass of propane = 0.63 x 44 = 27.7g
