To allow the metal elements copper and aluminum to interact - thus allowing electrolysis to take place - the metals must not be dry: they must be in contact with an electrically-conducting fluid which is called an electrolyte.
Even the moisture in damp air can act as an electrolyte, so, unless the metals are very closely and well-bonded together mechanically, such as by welding, electrolysis will occur if such metals are just in close contact and are unprotected from the atmosphere.
Such electrolysis is called corrosion.

When the two metals are connected, the aluminium will corrode because of electrolytic action. Because of that, there is a high risk of the connection overheating and causing a fire.
By using special connectors designed to join copper and aluminium, the join will be OK. Otherwise, it will become very dangerous.

When 2.50 g of Cu reacts with oxygen the copper oxide product has amass of 2.81 g what is the simplest formula of the copper oxide?
if 75grams of oxygen react how many frams of aluminum are required
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Equation needed Copper II oxide reacts with elemental C to form elemental copper and carbon dioxide Aluminum metal and iron III oxide react to produce aluminum oxide and elemental iron?
1. Copper(II) = Cu2+ Oxygen = O2- Carbon = C4- 2CuO + C2 --> 2Cu + 2CO2 Copper (II) oxide + Carbon --> Copper + Carbondioxide 2. Aluminum = Al3+ Iron (III) = Fe3+ Oxygen = O2- 2Al + Fe2O3 --> Al2O3 + 2Fe Aluminum + Iron (III) oxide --> Aluminumoxide + Iron
Why does aluminum react with three bromine atoms?
When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
Why does copper ii sulfate react with aluminum?
Yes. Iron is more reactive than copper, so will displace it from a compound. If you put a piece of iron into copper sulfate solution, it will be soon coated with a deposit of orangey red copper.CuSO4 + Fe --> FeSO4 + Cu
Will Sodium hydroxide react with copper?
No. Zinc and aluminum will react though.
When Aluminum is allowed to react with the copper sulfate What is the Limiting reagent?
usually it will be copper sulfate as a limiting reagent
What are three metals that react with air and water in the atmosphere?
Aluminum, copper, and iron.
If 0.25 g of Aluminum react with 0.6g of Copper sulfate then which one is the limiting reactant?
Aluminum would be the limiting reagent
Will aluminum nitrate and copper nitrate react if combined in ammonium carbonate solution?
A chemical reaction.
Why acidic food should be stored in metal containers made up of copper and aluminum?
acidic food related ingridients can react with metal , copper and aluminum , THUS making it poisonous to the human body
Which is lighter-copper or aluminum?
Aluminum
What kind of copper looks like aluminum?
The kind of copper that looks like aluminum is tinned copper.
When 2.50 g of Cu reacts with oxygen the copper oxide product has amass of 2.81 g what is the simplest formula of the copper oxide?
if 75grams of oxygen react how many frams of aluminum are required
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.
