Answer:
Substrate:alkyl halide
Leaving group: Cl
Organic product: The nitrile
Inorganic product: Cl-
Nucleophile: CN-
Explanation:
An SN2 reaction is a concerted bimolecular reaction. Concerted means that it involves two reactions taking place at the same time while bimolecular means that the rate determining step involves two molecules. The cyanide ion attacks the alkyl halide from the rear. In the transition state, the leaving group (Cl-) is departing while the nucleophile (CN-) is forming a bond to the alkyl halide simultaneously. The alkyl halide is the substrate in the reaction. The organic product is the nitrile shown in the image attached.
Answer:
Explanation:
In this case, we have to start with the <u>reagents</u>:
The compounds given by the problem are:
-) <u>Nitrogen gas</u> =
-) <u>Water vapor</u> =
-) <u>Aluminum oxide</u> =
Now, we can put the products in the <u>reaction</u>:
When we <u>balance</u> the reaction we will obtain:
Now, for the enthalpy change, we have to find the <u>standard enthalpy values</u>:
With this in mind, if we <u>multiply</u> the number of moles (in the balanced reaction) by the standard enthalpy value, we can calculate the energy of the <u>reagents</u>:
And the <u>products</u>:
Finally, for the total enthalpy we have to <u>subtract</u> products by reagents :

Answer:
fluoride ion
Explanation:
If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
