What else can I help you with?
Metal that is below halfway in the reactivity series - but if you read the name differently it sounds as though its out in front?
I've got that chemistry homework. It's aluminium. Basically, it forms an oxide around it so it doesn't react but it is reactive without the oxide, such as in a powder.

Lead fits this description. In the reactivity series, lead is below halfway. When reading the name "lead" differently, it sounds like "led," which gives the impression of being out in front or leading.
Why does aluminum seem unreactive even though its high in the reactivity series?
Well, honey, aluminum might be high up in the reactivity series, but it's got this tough outer layer of aluminum oxide that forms and protects it from further reactions. So, while it technically could react with stuff, that layer is like a shield, making it seem all chill and unbothered by the world. Think of it as aluminum's way of saying, "I'm too fabulous to react with just anyone."
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.
What is the raw materials of Aluminum?
Aluminium is extracted from an ore called bauxite. In can be used as a raw material though, such as when alloys are made with aluminum additions. Aluminium is not found natuarally as aluminum.

Is trans metal reactive or not?
I don't know what you mean by "trans metal".Transition metals vary in reactivity from platinum and gold (almost inert) to zinc (pretty reactive), though less so than, say, aluminium (you may not think of aluminium as reactive, but that's because it's so reactive it instantly reacts with oxygen in the air to form a thin transparent layer of aluminium oxide, which is pretty non-reactive) or magnesium or sodium.
Cross reactivity of dengue fever test and hepatitis c?
No cross-reactivity even though they are in the same family.
What is the chemical formula for aluminum hydrogen?
Sorry there is no such compound as aluminium hydrogen though there is aluminium hydride - AlH3 or if that isn't it aluminium hydroxide - Al(OH)3
Why is carbon sometimes listed in the reactivity even though it is not a metal?
Carbon is sometimes included in reactivity series because it can participate in reactions where it either gains or loses electrons. It can form compounds with both metals and non-metals, making it a versatile element in chemical reactions. Additionally, carbon's ability to form allotropes with varying properties adds to its reactivity.
Why are carbon and hydrogen in the reactivity series?
"Carbon and hydrogen are often included in the reactivity series even though they are non-metals. Carbon is included because this helps to explain what happens in the extraction of iron in a blast furnace. Hydrogen is included because any metal below it will not react with dilute acids."http://www.frankswebspace.org.uk/ScienceAndMaths/chemistry/reactivitySeries.htm
Are inmates supposed to have some time outdoors?
Depends on the lockdown, though generally most do spend time outdoors
What will happen to a compass needle when an aluminium bar is kept in between them?
The compass needle will be unaffected by the presence of the aluminium bar as it is not magnetic. Aluminium is not a magnetic material, so it will not interfere with the function of the compass needle.
Can Maltese dogs live outdoors?
Yes. It might not like it as much as being an outside dog though.
Can indoor training shoes be used outdoors?
They can, though rough surfaces may wear them down quickly.
Why is aluminium recycled even though it is the most abundant metal in the earths crust?
because it requires expensive electrolysis to convert aluminium ore into aluminium, and there are few places where its ore is concentrated enough to be economically viable.
