Explanation:
We define the formal charge on an atom in a molecule as the charge it carries assuming that electrons in all chemical bonds of the molecule were shared equally between atoms irrespective of the electronegativity of each atom.
The formula for calculating the formal charge on an atom in a molecule is;
Formal Charge = [number of valence electrons on neutral atom] – [(number of lone electron pairs) + (½ number of bonding electrons)] ·
The formal charge on the two nitrogen atoms in diazomethane is obtained as follows;
Middle nitrogen atom = 5 – 8/2 – 0 = +1
Last nitrogen atom = 5 – 4/2 – 4 = –1
The Lewis structure of the molecule is shown in the image attached.
The electons are in the atmosphere
<u>Answer:</u>
NO ---> N +2 and O -2
<u>Explanation:</u>
Oxidation numbers are assigned to the elements of a compound to keep a track of the number of electrons each atom has.
Here we have a compound NO (Nitrogen Oxide). The Nitrogen is assigned an oxidation number of +2 while Oxygen in this compound is assigned an oxidation number of -2.
So the algebraic sum of the oxidation numbers of the elements in the compound NO is equal to zero.
Answer:
Option g. (9)
Explanation:
Let's think the equation. In a combustion, the oxygen is the reactant and the products are CO₂ and water. So the reaction must be:
C₉H₈O₄ + O₂ → CO₂ + H₂O
If balance the equation would find out that the coefficient of oxygen is 9 .
C₉H₈O₄ + 9O₂ → 9CO₂ + 4H₂O
