Question

Help me to finish my lab report. Please

3. What role did oxidation-reduction play in the need for restoration?

5. What is acid rain? Discuss its causes and effects.

Please can you type the answer. Thanks

Answer 1

* oxidation :- loss of electrons is known as onidation' Both *Reduction - gain of electrons are called Reduction. * Redon Reactions: The reactions in which foxidation and reduction takes place simultaneously is called Redox Reactions. Therefore Redoxe Reactions are mostly a dual process that involves electron donors (reducing agent) and up acceptors Coxidizing agent) - aNaOH + H2 ana +2H2o - Vo r Reductia TH2 awatt 20H 2 Na + 2H2O onidation. oxidation numbery

when burning of fossil fuels. like release of 802 and No when sor and no 2 gases are present in atmosphere react with water to form respective acids like Nitric acid and sulphuric acids. due to these formation comes acid rain. * Effects: - when pH of rain water is less than sob, it is called acid rain. when acid rain flows in to the rivers, it lowers the pH of the river water, the survival of aquatic life in such rivery become difficult. . Acid rain also removes minerals soil the grow. * and that from to nutrients trees need
