When a grey coloured object made of metal A is left exposed to moist ar for considerable time, it gets covered with a red-brown tlaky coating by the proces called B, which eats up the whole object gradually. It is said that the presence of C and D is necessary for this process to take place. a. Name the metal A of which the object is made. b. Name the process B. c. What are Cand D?

Answer 1

Henry music site of the photos of the day so when we apply 1 litre of oil and it then it will have difficulty in performing photosynthesis as the oil will block the stomata board and then it will not be able to release out oxygen and it will also not be able to take carbon dioxide or some other necessary nutrients for its photosynthesis

b. a. the metal could be iron or aluminium but I am not sure
b. MS obviously corrosion effects any other metal and if it is Iron then it will be rusting
c. cmbr obviously motion and oxygen because of the presence of moisture and oxygen any metal get reacted with oxygen to form metallic oxide and it is in the presence of moisture in this reaction takes place for BSE NSE NTR motion and oxygen

sorry about a
