Answer:
Explanation:
Let us consider the reaction:
2 NO₂ + 1/2 O₂ ⇄ N₂O₅
The rate of formation of a substance is equal to the change in concentration of the product divided the change in time:
![r(N_{2}O_{5})=\frac{\Delta [N_{2}O_{5}] }{\Delta t}](https://tex.z-dn.net/?f=r%28N_%7B2%7DO_%7B5%7D%29%3D%5Cfrac%7B%5CDelta%20%5BN_%7B2%7DO_%7B5%7D%5D%20%7D%7B%5CDelta%20t%7D)
The rate of disappearance of a reactant is equal to to the change in concentration of the reactant divided the change in time, with a negative sign so that the rate is always a positive variable.
![r(NO_{2})=-\frac{\Delta[NO_{2}] }{\Delta t}](https://tex.z-dn.net/?f=r%28NO_%7B2%7D%29%3D-%5Cfrac%7B%5CDelta%5BNO_%7B2%7D%5D%20%7D%7B%5CDelta%20t%7D)
![r(O_{2})=-\frac{\Delta[O_{2}] }{\Delta t}](https://tex.z-dn.net/?f=r%28O_%7B2%7D%29%3D-%5Cfrac%7B%5CDelta%5BO_%7B2%7D%5D%20%7D%7B%5CDelta%20t%7D)
The rate of the reaction is equal to the rate of any substance divided its stoichiometric coefficient. In this way, we can relate these expressions:
Answer:
B
Explanation:
When nitrogen and aluminum form an ionic bond, the formula of the ionic compound is AlN. Aluminum forms a cation Al⁺³ and nitrogen forms an anion N⁻³. When each cation of Al⁺³ combines with an anion of N⁻³, AlN or aluminum nitride is formed

The correct answer would be... Scientific
Answer:
B. Aromatic
Explanation:
Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.
For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.
