Why are alloys harder than metals?
Alloys are not necessarily harder or stronger than pure metals. For example gallium and aluminum form an alloy that is extremely weak. Many of the alloys we know of are stronger than pure metals because those are the ones we find most useful. In most pure metals, there will be gaps in between atoms. In many alloys we fill in those gaps with some other type of atom, adding extra support.
The properties of alloys most resemble?
metals :) ~_~ ^_^ @_@ A_A !_! *_* ^-^im kinda board but the answer is metal hoped it helped.
What happens if ferrous metals are left outside?
There is only one ferrous metal-iron- but there are many ferrous alloys. Iron and the iron in most of the alloys will oxidize quickly-that is, rust.

Is an alloy a mixture?
Most alloys are usually mixtures, so that'd be your answer.
Are alloys genrally weaker of stronger the pure metals?
Most alloys are meant to be stronger: bronze >> copper etc.

What are three advantages of some alloys when compared to pure metals?
Alloys are sometimes more useful than pure metals because alloys are stronger - or tougher (toughness is resistance to fracture). Pure metals tend to be softer than alloys and therefore tend to get dented, scratched, or broken/fractured more easily. Alloys are often lower cost than pure metals but not necessarily so. As an example, stainless steel is more expensive than pure iron.
What other metals is iron in?
Though iron is in a variety of alloys the most prominent is probably steel.
Is an alloy a mixture or compound?
Most alloys are mixtures, because the proportions between or among the metals in them can vary.
Are solid solutions common?
Yes. Most metals used in practice are alloys, which are often solid solutions.

Is a aluminium car body a element compound or mixture?
Aluminum is an element, most aluminums are alloys of aluminum and other metals.
What metals are not attracted to a magnet?
Every single one except iron, nickel and cobalt. Most alloys - but not all of them - of these metals are also magnetic, such as steel. ( just an extra fact for you there (: )
What reacts with metal?
Non-metals can react with metals to form ionic or covalent compounds. Mercury will react with most of the metals to form amalgams. Mixture of metals will lead to the formation of alloys.
