Atomic number of element Z is 16. Is Z a metal or a non metal.

An alloy is made up of two metals and one non-metal- copper, tin and phosphorus. What is the name of that alloy?

A strip of metal X is dipped in the blue coloured salt solution YSO_(4) . After some time, a layer of metal Y from the salt solution is formed on the surface of metal strip. X metal Z is used in galvanisation whereas metal Y is used in making electric wires. Metal X and metal Y together form an alloy Z. (a) What could metal X be. (b) What could metal Y be ? (c) Name the metal salt YSO_(4) . (d) What type of chemical reaction takes place when metal X reacts with salt solution YSO_(4) ? Write the equation of the chemical reaction involved. (e) Name the alloy Z.
