The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1".
In general it is known that nonmetals are very poor
conductors of heat and electricity. The nonmetals that are solid are normally
very brittle and has very little or no metallic luster at all. Nonmetals are
highly reactive and show variety of chemical properties. It can also be pointed
out that the nonmetals gain electrons very easily.
When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.
Answer:
Explanation:
Combustion releases energy in a single step in the form of light and heat. Whereas in respiration, energy is released in steps and is stored in the form of ATP.
Filtration is useful for separating sediments that are carried in water for easy drinking without the risk of disease - an example of this is a water purifier
The answer is D because when a scientist publishes a book it helps other scientists and other scientists can help the scientists that publish the book.
