The compound reactions includern ca + o2 → Caorn CaCO3 → CaO + CO2 rncacl2 + AGNO3 → AGCl + ca (no3) 2 rncabr2 + CL2 → CACL2 + BR2
Accepted Answer
Reaction 1:
Ca + O2 → CaO
This is a combination reaction in which calcium (Ca) reacts with oxygen (O2) to form calcium oxide (CaO).
Reaction 2:
CaCO3 → CaO + CO2
This is a decomposition reaction in which calcium carbonate (CaCO3) breaks down into calcium oxide (CaO) and carbon dioxide (CO2).
Reaction 3:
CaCl2 + 2AgNO3 → 2AgCl + Ca(NO3)2
This is a double displacement reaction in which calcium chloride (CaCl2) and silver nitrate (AgNO3) react to form silver chloride (AgCl) and calcium nitrate (Ca(NO3)2).
Reaction 4:
CABr2 + Cl2 → CCl4 + Br2
This is a substitution reaction in which a chlorine atom (Cl) from chlorine gas (Cl2) replaces a bromine atom (Br) in CABr2 to form carbon tetrachloride (CCl4) and bromine gas (Br2).
