The rusted piece of iron is to be identified and the reason is to be explained. Concept Introduction: Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction . Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction. A chemical reaction in which oxidation process and reduction process take place simultaneously is called a redox reaction . An oxidizing agent is a substance that has the capacity to oxidize the other substances and get reduced in a chemical reaction. A reducing agent is a substance that has the capacity to reduce the other substances and get oxidized in a chemical reaction. Non-metals are a better oxidizing agent than metals. They have the capacity to gain electrons and form negative ions. They have the capacity to oxidize the other substances and get reduced. Metals are a better reducing agent. They have a tendency to lose electrons and form positive ions. They have the capacity to reduce the other substances and get oxidized.

Question

Please note that it is correct and explains it rightly:The proportion of O, C and H in the graphite oxide is:a) Constant, for the quantities of functional groups of acids, phenols, epoxy, etc. its constantsb) Depending on the preparation method, as much oxidant as the graphite is destroyed and it has less oxygenc) Depends on the structure of the graphic being processed, whether it can be more three-dimensional or with larger crystals, or with smaller crystals and more borders.

Interpretation Introduction

Interpretation:

The rusted piece of iron is to be identified and the reason is to be explained.

Concept Introduction:

Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction.

Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.

A chemical reaction in which oxidation process and reduction process take place simultaneously is called a redox reaction.

An oxidizing agent is a substance that has the capacity to oxidize the other substances and get reduced in a chemical reaction.

A reducing agent is a substance that has the capacity to reduce the other substances and get oxidized in a chemical reaction.

Non-metals are a better oxidizing agent than metals. They have the capacity to gain electrons and form negative ions. They have the capacity to oxidize the other substances and get reduced.

Metals are a better reducing agent. They have a tendency to lose electrons and form positive ions. They have the capacity to reduce the other substances and get oxidized.
