Was copper or arsenic discovered first?

Cu forms two oxides For the same amount of Cu twice as much oxygen was used to form the 1st oxide than to form the 2nd one What is the ratio of the valencies of copper in the first and second oxides?
The ratio of the valencies of copper in the first and second oxides is 2:1. This is because for the first oxide, twice as much oxygen was used compared to the second oxide, so the valency of copper in the first oxide will be 2 while the valency in the second oxide will be 1.
Which came first copper bronze or iron?
Copper was the first metal used by humans, dating back to around 9000 BCE. Bronze, an alloy of copper and tin, came next around 3300 BCE. Iron was used last, with widespread use starting around 1200 BCE.
Which metal is best at reclaiming copper from the used copper chloride solution?

When was copper first used as a material for bath tubs?
Copper was first used for bath tubs as a material in late 1910, the reason this was used as a material is because copper as an element is a great heat conductor and can also retain heat for a longer time that other well known materials.
