B a biotic factor is something living that affects the population of an organism
The Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−
To determine which is the Brønsted-Lowry base in the given reaction:
NH2−+CH3OH→NH3+CH3O−
First, we will write the equation for the reaction properly
The equation is:
NH₂⁻ + CH₃OH → NH₃ + CH₃O⁻
Now, to determine which among the species in the above reaction is the Brønsted-Lowry base, we will start by defining what a <em>Brønsted-Lowry base</em><em> </em>is.
A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the H⁺.
In simple terms, a Brønsted-Lowry base is a proton acceptor.
In the above reaction, NH₂⁻ is the species that is capable of accepting a proton and it has a lone pair of electrons to bond to the H⁺.
∴ NH₂⁻ is the Brønsted-Lowry base in the reaction
Hence, the Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−

Hello there!
In this case, since the ionization of benzoic acid is:
Whereas the corresponding equilibrium expression is:
Now, we insert the acidic equilibrium constant and the reaction extent x, to write:
Thus, by solving for x, we obtain:
Which is also:

Answer:
2s² 2p⁵
There are seven valance electrons in fluorine.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other.
Properties of fluorine:
1. it is yellow in color.
2. it is flammable gas.
3. it is highly corrosive.
4. fluorine has pungent smell.
5. its reactions with all other elements are very vigorous except neon, oxygen, krypton and helium.
Electronic configuration of fluorine:
F₉ = 1s² 2s² 2p⁵
Valance electrons in fluorine are 2s² 2p⁵.
Valance Orbital configuration:
2s² 2p⁵
There are seven valance electrons in fluorine.
Answer:
2.409*10^24
Explanation:
If I am not mistaken you are supposed to do 4*6.022*10^23. This will allow for it to be converted.
