Answer:
Explanation:
Mixture: is combination of one or more substances mix together.
• The properties of the mixture are not same and contains the properties of all those component present in it.
• it is a combination of one or more Pure substances and can be separated by simple physical methods.
• it have varying boiling and melting point
Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means.
The components of a homogeneous mixture are in the same phase oar in dissolved form so it look like one component.
Examples are:
• Salt water is mixture of water and NaCl and can be separated by physical mean.
• Air: mixture of gases
Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.
The component of heterogeneous mixture not fully mixed are different in color or different in phases or not soluble. So one can easily see the difference in the component of the mixture
Examples is
• mixture of salt and sand
• mixture of water and sand
I think it is that they use the same process which is oxidation
The element having valency of 1 is ~
