The answer is longitudinal waves
In a heterogeneous mixture, you can clearly see the distinction between the different substances within the mixture. e.g. fruit salad, paella, nachos
in a homogeneous mixture, it is still made up of different substances, but there is no way of distinguishing between them just from appearances. they have the same uniform composition throughout. e.g. salt water; you know it is made of salt and water, but the salt is dissolved uniformly throughout that you cannot tell.
hope that helps :)
Answer : The type of compound created is Ionic compound and the chemical formula is KCl.
Explanation :
- Potassium has 1 electron in its valence shell and chlorine has 7 electrons in its valence shell.
- The potassium loses 1 valence electron & make a positive charged ion and chlorine picks it up & make a negative charged ion and then they attract to each other.
- Potassium and chlorine atom combine to form potassium chloride by the ionic bonding.
- An ionic compound is made of a metal and non-metal element. And in this case, potassium is a metal element and chlorine is a non-metal element.
The ionic compound formation is,

The Chemical formula is KCl.
