<h3>Answer
</h3>
Option C= ions are exchanged between two compounds.
<h3>Explanation
</h3>
A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products. For example,
Na2S + 2HCl → H2S + 2NaCl
Option D is incorrect because electrons are exchanged between the atoms in oxidation –reduction reactions.

<span>As the percentage is the mole fraction multiplied by 100:
</span>

<span>The mole fraction will be the percentage divided by 100, thus:

There are usually 3 topics used to compare types of radiation:
Ionising ability
Penetrative power
Range in air
Ionising ability
Alpha radiation has strong ionising ability, while beta only has moderate ionisation and gamma is very weakly ionising.
Penetrative power
Alpha particles are weakly penetrating, stopped by paper, while beta particles have stronger penetrating ability, stopped by skin and gamma radiation is very strongly penetrating, stopped only by thick layers of lead.
Range in air
Alpha particles- range of only a few centimetres
Beta - range of up to one meter
Gamma- infinite range in air.
Hope this helps:)
Velocity- It is basically the speed of an object but with a particular direction.
Uniform Acceleration- It is a type of motion in which the velocity of a object changes by an equal amount in every equal period of time.
