Detailed explanation-1: -Bronze was made by heating the metals tin and copper and mixing them together. As the two metals melted, they combined to form liquid bronze. This was poured into clay or sand moulds and allowed to cool.
Detailed explanation-2: -Bronze is made when copper is heated and mixed with tin, creating a stronger metal than copper. Materials like wood and stone were also used for tools, but bronze was better for cutting and chopping, and was easy to shape.
Detailed explanation-3: -You can remove tin from bronze (copper-tin alloys) and leave behind the copper. However, doing so may not leave you with copper in an easy to use form. Tin is a less reactive metal than copper. Tin reacts with all acids, like HCl, while copper only reacts with oxidizing acids, like HNO3.
Detailed explanation-4: -When you mix copper and tin, you make bronze. No chemical reaction occurs.
Detailed explanation-5: -Tin’s principal function is to strengthen these bronze alloys. Tin bronze is strong and hard and has very high ductility. This combination of properties gives them a high load-carrying capacity, good wear resistance, and the ability to withstand pounding.
