D. A new substance with properties different from either of the liquids was formed.
Explanation:
This is a simple chemical reaction. When chemical reactions occur, bonds are simply broken and rearranged and new ones formed. Formation of new compounds can be seen and clearly observed. These compounds are completely different in properties from the atoms and compounds that combines to form them.
If they still share the same property in anyway, then, there was only a physical combination of the compounds and this implies the formation of a mixture
D. A new substance with properties different from either of the liquids was formed.
The correct option that is the answer for the question is option d
Explanation:
In the given question two liquids of different colours are mixed together. One of them has yellow colour, while the other is colourless on mixing we see that the new substance that is formed is neither yellow nor colourless.
And the mixture that is formed is a substance which is not liquid and solid of red colour and we can conclude, that the mixture form does not retain any property of the elements from which it is made. Hence we can say a new substance with different properties are formed.
Silicon is a popular semi-conductor. The process of doping either creates an excess or lack of electrons. In the case of silicon, the dopant is arsenic which has greater valence electron than silicon. Arsenic then donates an electron resulting to an excess of electrons. A new type or better type of semi-conductor is created. Silicon conduct greater electricity.
