Which shows an isomer of the molecule below?

babunello [35]

Above question is incomplete. Complete question is attached below
.......................................................................................................................

Correct Answer: Option D i.e. CH3CH2CH2CH2CH3

Reason:
Isomers are the compounds having same molecular formula, but different structural formula.

The molecular formula of the compound is C5H12

The compound present is question (i.e. 2-methyl butane) and option D (n-pentane) has same molecular formula. Hence, they are isomers.

However, compound present in option A, is the same compound provided in question. Hence, it is not an isomer. Compounds reported in option B and C has one carbon atom less and more, respectively as compared to the compound reported in question. Hence, they are also not isomers.

4. A galvanic cell is formed when two metals are immersed in solu- tions differing in concentration 1 when two different metals

Vanyuwa [196]

A galvanic cell is formed when two metals are immersed in solutions differing in concentration, when two different metals are immersed.

<h3>What is a Galvanic cell ?</h3>

In order to provide a pathway for the flow of electrons along that wire, the galvanic cell makes use of the ability to split the flow of electrons during the oxidation and reduction processes.
It forces a half-reaction and connects each to the other with a wire.
A galvanic cell is an electrochemical device that converts chemical redox reaction energy into electrical energy.
Electrically, it has a potential of 1.1 V. Oxidation takes place at the anode, which is a negative plate in galvanic cells. It is a positive plate where the reduction happens.
An electrochemical device called a galvanic cell transforms chemical energy's free energy into electrical energy. A photogalvanic cell produces species that are photochemically reactive.

Given the pH of 7. Explain how many hydroxide ions (-OH) and hydronium ions (H30+) are present in the solution.

irga5000 [103]

If the pH is 7, the solution is neutral, which means that it is an equal amount of acid and base.
