The diatomic molecule that is formed when two atoms share six electrons is N2.
The atomic number of nitrogen is 7 and its electronic configuration is 2,5. This implies that, nitrogen has 5 electrons in its outermost shell. To attain the octet structure, it needs 3 electrons more. To form a diatomic molecule, two nitrogen atoms come together and each donate three electrons, which are equally shared between the two, thus, each ends up having 8 electrons in its outermost shell.

The balanced chemical reaction is written as:
4Al + 3O2 = 2Al2O3
To determine the mass of oxygen gas that would react with the given amount of aluminum metal, we use the initial amount and relate this amount to the ratio of the substances from the chemical reaction. We do as follows:
moles Al = 16.4 g ( 1 mol / 26.98 g ) = 0.61 mol Al
moles O2 = 0.61 mol Al ( 3 mol O2 / 4 mol Al ) = 0.46 mol O2
mass O2 = 0.46 mol O2 ( 32.0 g / mol ) = 14.59 g O2
Therefore, to completely react 16.4 grams of aluminum metal we need a minimum of 14.59 grams of oxygen gas.
Answer : The correct answer for mole ratio of H₂O : H₃PO₄ = 6: 4 .
Mole ratio :
It is defined as mole of one substance to another substance in a balanced reaction . In the balanced reaction , the coefficient written before the substances are taken as moles of that substance.
The given balanced reaction between P₄H₁₀ and H₂O is :
P₄O₁₀ + 6 H₂O → 4 H₃PO₄
Mole of H₂O = 6
Mole of H₃PO₄ = 4
Hence mole ratio of Water : H₃PO₄ = 6 : 4
Answer:
The other signal that would indicate the presence of a C= C bond appears close to 3100 
.
Explanation:
Bands that appear above 3000 are often unsaturation diagnoses suggest. The band at 3000-
3100 is characteristics for C-H stretching frequencies and normally is overlaps with the ones for alkanes because it is a band of weak intensity.
