Answer:
1)CuCO3 ---heat---
--→CuO+CO2 ↑
2)HCl+NaSO4→ NaCl+H2SO4.no gas evolved
3)N2+H2→NH3↑
4)Na2CO3+H2SO4
→NaSO4+CO2↑+H2O
5)Na+H2O→NaOH+H2↑
Hope this will help u

________________
⚡CuCo3 is heated strongly it decomposes forming Copper oxide and carbon dioxide ( CO2 - gas ) .
⚡ Sulphuric dioxide gas which is colourless .
⚡Ammonia ( NH3 )
===> ( N2 ) + ( 3H2 ) →← 2NH3 + Heat
⚡Carbon dioxide gas ( CO2 )
⚡ Hydrogen gas
