Answer:
Separation by density
Explanation:
Mixtures are made up of two or more pure substances which tends to keep their individual identities. These components can be separated from each other by different physical techniques.
Mixtures are further classified as;
(i) Homogenous Mixture:
In this type of the mixtures the components are uniformly mixed and their properties as well as composition as uniform throughout. Such mixtures are also called as solutions.
The physical methods used to separate these components from each other are distillation (taking heat and pressure into account), Solvent extraction, Magnetic separation, Chromatography e.t.c.
(ii) Homogenous Mixture:
In this type of the mixtures the components are not uniformly mixed and their physical properties and composition are also not uniform.
The physical methods used to separate these components from each other are Filtration, Magnetic Separation, Centrifugation, Flotation e.t.c.
So, in given options the density can play role by settling the massive components of heterogenous mixture to sit at the bottom and separated
Can’t tell ya bc you didn’t list the answers
6:c
7: might be ice but im not really sure, hope you do well.
Explanation:
That statement is true
it was easy to organize 'all' the elements in a group of threes because back then they only knew about 15 - 20 elements
hope this helps
No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical.
