Question

2/Na2O-->NaOH-->Na2SO3--> SO2--> SO3-->H2SO4-->K2SO4-->AL2(SO4)3-->NA2SO4-->NA2CO3

Answer 1

2/

Na2O+ H2O----->2NaOH

2NaOH +SO2---->Na2SO3+H2O

Na2SO3+2HCl-----> 2NaCl +H2O+SO2

2SO2+O2----> 2SO3

SO3 +H2O----->H2SO4

H2SO4 +2KOH---->K2SO4+H2O

3K2SO4 +2AlCl3-->AL2(SO4)3+6KCl

Al2(SO4)3 + 6NaOH---->3NA2SO4+ 2Al(OH)3

Na2SO4 +2C +CO2---->NA2CO3 +CaS +CO2

Answer 2

Na2O+H2->NaOH

NaOH+SO2->Na2SO3+H2O

Na2SO3+H2SO4->H2O+Na2SO4+SO2

SO2+O2->SO3

SO3+H2O->H2SO4

H2SO4+KOH->K2SO4+H2O

K2SO4+Al(OH)3->Al2(SO4)3+KOH

Al2(SO4)3+NaOH->Al(OH)3+Na2SO4

Na2SO4 + H2CO3->Na2CO3 + H2SO4

Answer 3

Na2O+H2--->NaOH

NaOH+So2--->Na2So3+H2O

Na2SO3+H2SO4--->H2O+Na2SO4+SO2

SO2+O2--->SO3

SO3+H2O--->H2SO4

H2SO4+KOH--->K2SO4+H2O

3K2SO4+2AlCL3--->Al2(SO4)3+^KCl

AL2(SO4)3+NaOH--->Al(OH)3+Na2SO4

Na2SO4+H2CO3--->Na2CO3+H2SO4
