Answer:
1.01 V
Explanation:
From Nernst equation;
Ecell= E°cell- 0.0592/n log Q
Where;
Ecell= observed emf of the cell
E°cell= standard emf of the cell
n= number of moles of electrons transferred
Q= reaction quotient
Q= [Ag^+]^3/[MnO4^-] [H^+]^4
Q= [0.01]^3/[1.20] [1.50]^4
Q= 1.65×10^-7
Ecell= 0.88 - 0.0592/3 log 1.65×10^-7
Ecell= 0.88 - [0.0197×(-6.78)]
Ecell= 0.88 + 0.134
Ecell= 1.01 V
Answer:
<h2>Physical properties: H2SO4 is a colorless or slightly yellow viscous liquid with a pungent odor. It has a density of 1.84 g/mL, boiling point of 337 °C, and melting point of 10 °C. "Concentrated" sulfuric acid is 98% in water, and is the most stable form.</h2>
Answer:
An acid is substance that produces <u>H⁺ </u>ions in solution, which is also written as the hydronium ion <u>H₃O⁺</u>. A base is a substance that produces an ion with the formula <u>OH⁻ </u>and the name <u>hydroxyl</u> ion.
Explanation:
An acid is substance that produces H⁺ ions in solution, which is also written as the hydronium ion H₃O⁺. A base is a substance that produces an ion with the formula OH⁻ and the name hydroxyl ion.
Acid:
An acid is the substance that sour in taste and turns the color of litmus paper from blue to red.
pH of acid is less than seven.
Base:
An acid is the substance that bitter in taste and turns the color of litmus paper from red to blue.
The pH of base is 7-14.
Arrhenius gives the simplest definition of acid and base.
Arrhenius acid:
A substance that increase the concentration of hydronium ion in solution is called acid.
HNO₃ → H⁺ + NO₃⁻
(H₂O)
Arrhenius base:
A substance that increase the concentration of OH⁻ ion in solution is called base.
KOH → K⁺ + OH⁻

Explanation:
The question is incomplete because the image of the alcohol is missing. However, I will try give you a general picture of the reaction known as hydroboration of alkenes.
This reaction occurs in two steps. In the first step, -BH2 and H add to the same face of the double bond (syn addition).
In the second step, alkaline hydrogen peroxide is added and the alcohol is formed.
Note that the BH2 and H adds to the two atoms of the double bond. The final product of the reaction appears as if water was added to the original alkene following an anti-Markovnikov mechanism.
Steric hindrance is known to play a major role in this reaction as good yield of the anti-Markovnikov like product is obtained with alkenes having one of the carbon atoms of the double bond significantly hindered.
