if this is for a course with T4TS which i think it is as i searched the same question, its D aluminium and magnesium
What else can I help you with?
When was the process of anodising first used for industrial purposes?
Anodising is a electrolytic passivation process, used on metals to increase corrosion resistance and for better adhesion of paint. It was first used for industrial purposes in 1923, to protect seaplane parts from corrosion.
What method do we use to extract more reactive metals such as aliminium?
Through electrolytic reduction.
What is the reason for coating steel components with a special compound when they contact with an aluminum frame?
To stop electrolytic action causing corrosion. Dissimilar metals (especially steel and aluminium) form a battery when wetted with water. This battery will cause a small current flow in the metals which will then eat away at the aluminium. Coating one or the other components, provides an insulator, which stops the battery forming.
What is corrosion of metals?
The corrosion of metals is the gradual destruction by chemical reaction with its environment. This process involves the electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
Why does the electrolytic reduction of the metals in group 1 and 2 proceed under molten salt conditions?
ehh
Which combination of metals would electrolytic corrosion be most pronounced?
The two furthest apart in the galvanic series - for all practical purposes this is magnesium and Gold

What are some methods in minimizing corrosion among metals?
Metals are usually treated with a coating that helps minimize the forming of corrosion. Steel is treated to galvanize it from developing rust, which is a type of corrosion. Electroplating is another way to minimize corrosion in metals.
Is it ok to connect brass pipe to copper pipe?
Absolutely, positively, YES as both are non ferrous metals and there is no possibility of galvanic corrosion or electrolytic action taking place. Presuming your taking about RED BRASS as opposed to Yellow
Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
Can you call the corrosion of all metals as rusting?
No. Rust (iron oxide) only occurs in metals containing iron. A couple examples of different types of corrosion are galvanic corrosion and chloride pitting corrosion.
Is Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.

Is corrosion of metals is physical?
corrosion of metals is a chemical reaction between metal and oxygen in atmosphere. Oxidation of metals called corrosion. It affects the physical properties of metal in either way like rusting, colour change, life cycle shortening etc.
What is corrosion of metals?
The corrosion of metals is the gradual destruction by chemical reaction with its environment. This process involves the electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
What could it be if No water is coming out of water heater?
1- Internal corrosion as someone failed to install a dielectric fitting to prevent electrolytic action of dissimular metals which is contrary to all model codes2- Valve closed3- A pipe ruptured taking all available pressure
