What is ferrous alloy?
Ferrous alloys or metals are metals that consist mostly of iron (Fe). Steel is an iron-based alloy containing typically less than 1% carbon, where iron frequently contains 2% or more carbon.
Is brass an alloy?

Why are wooden bells not used in schools?
Answer Expert Verified Bells are made up of metals Rather than wood because according to the physical properties of metals, they have highly sonorous….and if you would bang a piese of wood instead of wood , no voice will be produced and hence your bell will be of no use…..!!!!!!!!!!
Why are bells made of metal and not of wood?
Complete answer: For starters, the materials used to make the bell should be sonorous. The bells are made out of metal and not wood because metals are sonorous, have elastic-like properties, and can sustain vibrations for longer durations than wood.
What happens when a metal combines with oxygen?
When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. Rust is a form of iron oxide and it forms slowly when iron is exposed to air. Iron can be transformed to steel (an alloy), which is more resistant to rust.
What happens when metal reacts with oxygen examples?
Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull is called tarnishing.
What metal does not react with oxygen?
Transition metals react with oxygen to form metal oxides. However, gold, silver, and platinum do not react with oxygen.
What happens when a metal reacts with a dilute acid?
When a metal reacts with dilute acid, salts are formed. During this reaction hydrogen gas is evolved. In other words, when a metal is added to dilute acids, salt and hydrogen gas are formed. Sulfate salts and chloride salts are formed when metals react with dilute sulfuric acid and hydrochloric acid.
