Which is the most reactive titanium aluminum or platinum?
Aluminium and titanium are about the same but aluminium is more reactive. platinum is the least reactive metal
What element is more expensive than gold?
Platinum
Why is that a piece of aluminium foil exposed to moist air does not corrode even though aluminium is more reactive than iron which easily rust?
Aluminium reacts very rapidly with the oxygen in the air to form a thin film of aluminium oxide covering the entire surface of the aluminium in the foil. This surface is invisible to the eye. Aluminium oxide is very resistant to chemical processes, like corrosion. It protects the aluminium underneath very well, so aluminium does not corrode in moist environments. If the aluminium is scratched, an new aluminium oxide film forms immediately, protecting the scratched part. Iron does not form a protective skin, because iron oxide has different chemical properties to aluminium oxide and is not able to protect the iron.
Which elements form amphoteric oxide?
Aluminium, Silicon, Zinc, Iron, and many more
Silver is more costly than iron because?
There are three major factors: Abundance: the rarer the metal is, the more expensive it will be. Demand: the greater the need or desire the more expensive the metal. Extraction: the harder a metal is to extract from its ore, the more expensive it is.
Suggest why aluminium is more expensive than iron?
Aluminium is more expensive than iron because of its lower abundance in the Earth's crust. It is also more costly to extract and refine aluminium due to the energy-intensive process of electrolysis. Additionally, aluminium has a higher demand and is used in a wide range of industries which further contributes to its higher price.
What properties applies to aluminum and not iron?
Aluminium is paramagnetic, iron is ferromagnetic Aluminium has a low density, iron is more dense Aluminium is not corroded in water, iron is easily corroded The hardness of aluminium is lower The price of aluminium is greater The melting point of iron is significantly greater The thermal and electrical conductivity of aluminium are more important Iron has a greater chemical reactivity ................................................................... etc.
Which is the most reactive titanium aluminum or platinum?
Aluminium and titanium are about the same but aluminium is more reactive. platinum is the least reactive metal
Why is iron cheaper than aluminium?
Enthalpy of combustion of aluminium is much more intensive than that of iron.
What happen when ferrous sulphate solution is store in aluminium can?
Aluminium is more reactive than iron (Fe) according to the reactivity series of metals. Thus, when Ferrous Sulphate solution is stored in Aluminium can, Aluminium being more reactive, displaces iron from its solution to form Aluminium sulphate and iron. :)
Which is more expensive gold or platinum?
platinum is more unique
Why platinum is more expensive than diamond?
Platinum is not more expensive than a beautiful, natural diamond.
Why do you need steel in concrete?
Since you're already using concrete, not much point in using the lighter, weaker, and more expensive aluminium. And lead is really weak, environmentally hazardous and more expensive than iron.
Would platinum or iron be more durable?
platinum
Which is stronger Aluminium corrugated sheets or galvanised iron corrugated sheets?
is galvanised iron more corrosion ressistant than aluminium
How much more dense is platinum than aluminium?
The density of platinum is 21,45 g/cm3.The density of aluminium is 2,7 g/cm3.The ratio is 8.
What is the disadvantage of aluminum?
Aluminium is more expensive than steel
