Omg that is that ( but I do not know this
pH = -log[H₃O⁺(aq)]
here the pH is given as 2.40.
Hence,
2.40 = -log[H₃O⁺(aq)]
log[H₃O⁺(aq)] = -2.40
[H₃O⁺(aq)] = 3.98 x 10⁻³ M
= 4.0 x 10⁻³ M
Hence, the hydronium ion concentration in juice is 4.0 x 10⁻³ M.
Since, the pH is less than 7, the juice is acidic.
Answer:
See explanation
Explanation:
The first step in this reaction is a unimolecular reaction. It involves the formation of the carbocation. This is so because tertiary alkyl halides only undergo substitution by SN1 mechanism due to sterric crowding.
The second step in the reaction is bi molecular. In this step, the carbocation now combines with the OH^- to yield the alcohol.
Net equation of the reaction is;
(CH3)3CBr + OH^- -------> (CH3)3COH + Br^-
The intermediate here is the carbocation, (CH3)3C^+
Answer:
fluorine (F), and chlorine (Cl) because they are both halogens and belong to the same group in the periodic table
Explanation:
The pair of non - metals in the elements given that will have similar properties are chlorine and Fluorine.
This is because they both are elements commonly known by the group name Halogens which belong to group 7A.
Properties of halogens include;
- They are very reactive, have single covalent bonds and readily form other compounds.
- In the gaseous state, they will form diatomic covalent molecules.
Whereas, helium is a group 8 element, oxygen is a group 6 element while carbon is a group 4 element.
