Question

1) zinc carbonate= zinc oxide+ carbon dioxide

2) potassium bromide+ barium iodide = potassium iodide + barium bromide

Balance the equations

Answer 1

1.

this reaction is a decomposition reaction in which zinc carbonate split intio zinc oxide and carbon dioxide

smbol equation :-

ZnCO3 -------------------------> ZnO + CO2

2.

2 KBr + Bal2 → 2 Kl + BaBr2

It is a double displacement reaction
