(1) 98% carbon, 1.5% iron and 0.5% other
elements
(2) 50% iron and 50% carbon
(3) 98% iron, 1.5% carbon and 0.5% other
elements
(4) 98% iron and 2% sulphur​

Answer 1

Answer:

2 50 percent iron nd 50 prcnt carbon

Answer 2

(3) 98% iron, 1.5% carbon and 0.5% other  elements.

Explanation:

• Steel is an alloy which mostly contains iron. Iron makes up to 98% of steel and carbon can make up 1.5% of steel and other elements make up 0.5% of steel.  

• Steel has the ability to cool down very quickly from very high temperatures after dipping in oil or water.  

• The physical property of steel includes high strength, high resistance to breakage, ductility, durability, lighter weight, resistance to corrosion.  
• The strength and weight ratio in steel is lowest than other metals so it provides more strength in less weight.
