2NaHCO3 → Na2CO3 + H2O + CO2 ___________

CH4 → C + 2H2O ________________

P4O10 + 6H2O → 4H3PO4 ______________

FeSO4 → FeO + SO3 _______________

CaCO3(s) → CO2(g) + CaO(s) _________________

Answer 1

`{ \rm{C _(7) H _(8) + 9O _(2) → 7CO _(2) + 4H _(2)O : { \tt{combustion}}}} \\ \\ {\rm{2NaHCO _(3) → Na_(2)CO _(3) + H_(2)O + CO_(2) : { \tt{decomposition}}}} \\ \\ { \rm{CH _(4) → C + 2H _(2) O :{ \tt{decomposition}} }} \\ \\ { \rm{P _(4)O _(10) + 6H _(2)O → 4H _(3) PO _(10) :{ \tt{combination}} }} \\ \\ { \rm{FeSO _(4) → FeO + SO _(3) : { \tt{decomposition}} }} \\ \\ { \rm{CaCO _(3(s)) → CO _(2(g)) + CaO _((s)) : { \tt{decomposition}}}}`
