Answer: N-N: 145 pm and 167 KJ/mol
N=N: 125 pm, 418 KJ/mol
And N2: 110 pm , 942 KJ/mol
Explanation: Bond length is inversily proportional to bond energy.
Greater the bond length , smaller the bond energy and vice-versa.
Glittering in the light
Opaque, not transparent
Light to the hold
D-block element
The mass of the reactants and the mass of the products are no equal.
Answer:
The balanced equation is.
CH₄ + 2O₂ → CO₂ + 2H₂O
Explanation:
CH₄ + O₂ --> CO₂ + H₂O
You have 4 H in reactant side. In order to balance the H, you add 2 in water, in product side.
Now, you unbalanced the O, because you have 2 O from CO₂ and 2 O from water. As you have 4 O in total, you add a 2 in the O₂ in the reactant side. C is balanced because you have 1 C on each side
