Answer:
N2 has a triple bond with its Lewis structure. Nitrogen has 5 valence electrons. Two nitrogen's have a total of 10 valence electrons. There will be 6 valence electrons that are unequally shared. We move them in the middle. Therefore, Each nitrogen gives three pairs of electrons to the to the other nitrogen atom. N2 has a total of 8 electrons which completes the octet rule.

Hey there !
<span>Convert Joule to KJ :
</span>
1 j ---------------- 0.001 kj
53.69 j ----------- Kj
Kj = 53.69 * 0.001
=> 0.05369 Kj
T = ΔH / <span>ΔS
T = 49.09 / 0.05369
T = 914.32ºC</span>
Given that Ka = 4.3 × 10^-4
At the half equivalence (Stoichiometric) point;
pH = pKa = - log (Ka)
Therefore; pKa = - log (4.3 ×10^-4)
= 3.37
Therefore; the pH at the half-stoichiometric point is 3.37
Answer:
21 Moles of Carbon is reacted
Explanation:
According to Balanced Chemical Equation, 2 moles of Hydrogen reacts with 3 moles of Carbon. Hence, for 14 moles of Hydrogen,
= (3 C × 14 H₂) ÷ 2 H₂
= 21 Moles of C
