. A green colour substance 'X' is heated strongly. Its colour changes to 'Y' and smell of burning sulphur is given out. a. Name the substances X and Y.
b. Name the type of reaction taking place.
c. Write the balanced chemical equation for the reaction.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The answer will be c
