[4]
2.
• 2HgO → 2Hg + O2
• PbO2 + SO2 → PbSO4
• CaCO3 → CaO + CO2
• NH4Cl → NH3 +HCl

Answer 1

Answer:

1.) Decomposition reaction

2.) Combination reaction

3.) Decomposition reaction

4.) Decomposition reaction

BALANCE REACTIONS

• 2Hg2O -> 2Hg+ 02
• Pb02 + SO4 -> PbSO2
• CaCO3 -> CaO3 + CO2
• NH3Cl -> NH3 + HCl
