Covalent bonds are non metals. Covalent bond (sharing), low temp, low temp, burn easily, poor, polar covalent is good and non-polar covalent is bad.
Ionic - metals and nonmetals, ionic bond is when electrons are gained or lost, high temp, high temp, doesn't burn easily, good, good
Answer:
Mg₃N₂ (magnesium nitride)
Explanation:
M(total) = M(mg) + M (n)
M (n) = M(total) - M(mg)
= 0.433g - 0.313g
= 0.12g
mole (N) = 0.12g / 14.0067 g/mol
= 0.008567
mole Mg = 0.313g / 24.3050 g/mol
= 0.012878
Mg = 0.012878 / 0.008567
= 1.5
N = 0.008567 / 0.008567
= 1
multiply by 2 to get whole numbers
Mg = 1.5 × 2 = 3
N = 1 × 2 = 2
Mg₃N₂ (magnesium nitride)
