Answer:

1)In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest

Answer 2

1️⃣In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.

2️⃣Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction: a more reactive metal will displace a less reactive metal from its compounds.

3️⃣The ferrous sulphate crystals are light green. Ferrous sulphate is also obtained as a by-product in the manufacture of titanium pigment and copper sulphate. The gas given out smells the characteristic odour of burning sulphur. The colour changes from light green to white colour

4️⃣For example: Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins. Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks
