Question

4. Give one example each of displacement, decompostion and combination reaction with
explanation​

Answer 1

Answer:

Zn+H2SO4=ZnSO4+H2 (displacement reaction)

2FeSO4=Fe2O3+SO2+SO3(decomposition reaction)

CaO+H2O=Ca(OH)2 (combination reaction)

Explanation:

we can call the first one displacement reaction because in this Zn replaces H2 to form ZnSO4

in the second one 2FeSO4 break's into Fe2O3,SO2 ,SO4 making it a decomposition reaction . The third one is a combination reaction because in this CaO combines with H2O to form Ca(OH)2………… hope you find it helpful
