<span>The natural source of acidity in rain water is all of the above. This is due to presence and abundance of carbon dioxide, nitrogen oxide, and sulfur dioxide in the atmosphere that can dissolve in rain water. Unpolluted rain water is made acidic due to CO2 and H2O in the air that forms carbonic acid.
Nitrogen oxide is mainly present due to the nitrogen fixation caused by lightning, while sulfur dioxide is mainly present due to volcanic eruptions. Other sources such as human activity can also contribute to acid rain. </span>
in absence of oxygen.
i have resd about in my biology textbook.
sorry i kniw this much
Answer:
(C) is the mechanism that increases the temperature between the photosphere and corona of the sun.
Explanation:
When a stars is converted from hydrogen to helium then this is known as proton -proton chain reaction.Due to this reaction the temperature between corona of the sun and photosphere increases.The main reason for increasing the temperature is exothermic reaction.
So the option C is correct.
(C) is the mechanism that increases the temperature between the photosphere and corona of the sun.
Answer:
Simply identify what elements are in a compound
Explanation:
For example in NaCl we have sodium (Na) and Chlorine (Cl)
In order to do this you would need to recognise the symbols for a certain element: O for oxygen; N for nitrogen; H for hydrogen etc.
People have died over drinking big amounts of water in fraternity initiations and while they where having the radio contest. So no there it's no life after hydration
