Answer:
Oxidation half reaction is written as follows when using using reduction potential chart
example when using copper it is written as follows
CU2+ +2e- --> c(s) +0.34v
oxidasation is the loos of electron hence copper oxidation potential is as follows
cu (s) --> CU2+ +2e -0.34v
Explanation:
1)Mid Ocean Ridge
2) Sea Floor Spreading; New crust is formed
3) It gets subducted and melts back into the mantle
4) 1. Molten Material (funny looking rocks)
2. Drilling Samples (age of rocks)
3. Magnetic stripes
5) Subduction: Old oceanic crust is more dense and sinks
6) Sonar
7) Trench
8) Sea floor spreading
9) Subduction
10) Mid ocean ridge
