Question

Arrange the metals Na, Ag,Mg,Zn and Au in increasing order of their chemical reactivity.​

Answer 1

Answer:

Ag <  Fe < Zn < Na

Explanation:

Reactivity is the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy. The reactivity series ranks metals by how readily they react. More reactive metals displace less reactive metals from their compounds and react with water. sodium or potassium phosphide release phosphine gas when they contact water. Alkali metal cyanide salts, such as sodium or potassium cyanide, slowly release deadly hydrogen cyanide gas on contact with water.

Hope it helps you!

Answer 2

Answer:

Au<Ag<Zn<Mg<Na

Explanation:

If we start from Na then it will be in decreasing

so I started from Au as it is a nouble metal and will not react with any substance in ordinary condition
