Answer 1

Answer:

Corrosion can be defined as the process through which refined metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides. ... The rusting of iron involves the formation of iron oxides via the action of atmospheric moisture and oxygen.

Answer 2

Answer = 12

Or

Answer is arrived at by seeing a pattern in the problem

In 1+1, take the square of 1 which is 1 and multiply this 1 by 5 to get the product 5 (RHS)

In 2+2, take the square of 2 and multiply the result by 5 to get 4x 5=20 (RHS)

In 3+3, take the square of 3 and multiply the result 9 by 5 to get 9x 5=45 (RHS)

Applying the above rule for 4+4, we write

4^2 x 5 = 16 x 5 = 80

Therefore, 4+4 = 80
