Batteries work by letting charged ions flow through an electrolyte solution.

Semmy [17]

Answer:

Batteries work by letting charged ions flow through an electrolyte solution.

A battery is a device that consists of one or more electrochemical cells that can convert stored chemical energy into electrical current. Each cell consists of a positive electrode, or anode, a negative electrode, or cathode, and electrolytes that allow ions to move between the electrodes, allowing current to flow out of the battery to carry out its function.

Explanation:

Its operation is essentially based on a reversible chemical process called reduction-oxidation, in which one of the components is oxidized and the other is reduced; that is, a process whose components are neither consumed nor lost, but merely change their oxidation state, and which in turn can return to their original state under the right circumstances.

Select all of the chirality centers in the structure. a selected atom will turn green.

scZoUnD [109]

Answer:

The answer is C is attached to four unique gatherings A, B C and D, Thus it frame two optical isomers as the perfect representations of one another.

Explanation:

A critical class of isomers in which mixes have the equivalent sub-atomic recipe and structure, yet the distinction emerges from the introduction of the gatherings in the 3D space. Optical isomers are called as enantiomers. Enantiomers are optical isomers whose identical representations are non-superimpose. They turn the plane enraptured light inverse way. Optical action is characterized as the capacity of a choral atom to pivot the plane energized light. The enantiomers that pivots the plane energized light a clockwise way is called extraordinary, while the one that turns the plane spellbound light an anticlockwise way is called rotatory. Basics , Centrality is the major behind the optical movement of a natural atom. Choral focus: A'C' particle in a particle turns into a choral focus when all the four valences of that molecule are fulfilled by synthetically unique gatherings.

Classify which compounds will dissolve in water and which ones will not dissolve in water.

vredina [299]

Answer:

Dissolves in water: Acetone, 1-propanol, Methanol

Do not dissolve in water: Hexane, Decane

Explanation:

From the principle that like dissolves like,polar substances will dissolve in polar solutions, while non-polar substances will dissolve in non-polar substances.

Water is a polar solution, therefore, polar substances will dissolve in it.From the given options:

Acetone is a polar molecule, therefore, it will dissolve in water.

1-propanol is a polar molecule, therefore, it will dissolve in water.

Hexane is a non-polar molecule, therefore, it will not dissolve in water.

Methanol is a polar molecule, therefore, it will dissolve in water.

Decane is a non-polar molecule, therefore, it will not dissolve in water
