The ability of two or more substances to combine to form other substances is called Reactivity.

The atmosphere is a mixture of several gases. Nitrogen is the most abundant gas in the atmoshere and oxygen is next to it. It is 78% in the atmosphere and 21% is oxygen. Remaining 1% is all other gases like argon, hydrogen, neon, etc...

Thermoset, or thermosetting, plastics are synthetic materials that strengthen during being heated, but cannot be successfully remouldedor reheated after their initial heat-forming. This contrasts withthermoplastics, which soften when heated and harden and strengthen after cooling. Thermoplastics can be heated, shaped and cooled as often as necessary without causing a chemical change, while thermosetting plastics will burn when heated after the initial moulding.

Agriculture would be a good example of a purely competitive industry.

Most producers use sun light for making their energy in the process of photosynthesis. The energy they prepared is sugar and glucose. 

Sometimes the solid particles in a liquid are very small and can pass through a filter paper. For such particles, the filtration technique cannot be used for separation. Such mixtures are separated by centrifugation.
