Question

Balance the following equation NaCl(aq)+H2O(l)----------→NaOH(aq)+Cl2(g)+H2(g) NaHCO3---------→Na2CO3+H2O+CO2 Fe2O3+ Al------------→Al2O3+Fe BaCl2+H2SO4-----------→BaSO4+H2

Answer 1

$\dag \: \: \: \sf NaCl(aq)+H_2O(l) \longrightarrow NaOH(aq)+Cl_2(g)+H_2(g)\\ \\ > \boxed{\bf{ \tiny {2NaCl(aq) + 2H_{2}O(l)\longrightarrow 2NaOH(aq)+Cl_2(g)+2H_2(g)}}}$

$\dag \: \: \: \sf{NaHCO_3 \longrightarrow Na_2CO_3+H_2O+CO_2} \\ \\ > \boxed{ \tiny{ \bf 2NaHCO_3 \: \longrightarrow Na_2CO_3+H_2O+CO_2}}$

$\dag \: \: \: \sf{Fe_2O_3+ Al \longrightarrow Al_2O_3+Fe} \\ \\ > \boxed{ \tiny{\bf{Fe_2O_3 + 2Al \longrightarrow Al_2O_3+2Fe}}}$

$\dag \: \: \: \sf{BaCl_2+H_2SO_4 \longrightarrow BaSO_4+H_2 + Cl_2 } \\ \\ > \boxed{ \tiny{\bf{BaCl_2 + H_2SO_4 \longrightarrow BaSO_4+H_2 + Cl_2 }}}$
