Explanation:

1. For \(2Na + Cl_2

ightarrow2NaCl\), it is a combination reaction as two substances combine to form one product.

1. For \(2H_2O

ightarrow2H_2 + O_2\), it is a decomposition reaction as one substance breaks down into two substances.

1. For \(CH_4+2O_2

ightarrow CO_2 + 2H_2O\), it is a combustion reaction (also a redox reaction) as a hydrocarbon reacts with oxygen.

1. For \(Zn + 2HCl

ightarrow ZnCl_2+H_2\), it is a single - displacement reaction as zinc displaces hydrogen from hydrochloric acid.

1. For \(AgNO_3+NaCl

ightarrow AgCl + NaNO_3\), it is a double - displacement reaction (also a precipitation reaction as \(AgCl\) is precipitated).

1. For \(2KClO_3

ightarrow2KCl + 3O_2\), it is a decomposition reaction.

1. For \(Ba(OH)_2+H_2SO_4

ightarrow BaSO_4+2H_2O\), it is a double - displacement reaction (also a neutralization reaction as an acid and a base react).

1. For \(4Fe + 3O_2

ightarrow2Fe_2O_3\), it is a combination reaction.

1. For \(2C_2H_6+7O_2

ightarrow4CO_2 + 6H_2O\), it is a combustion reaction (also a redox reaction).

1. For \(Cu + 2AgNO_3

ightarrow Cu(NO_3)_2+2Ag\), it is a single - displacement reaction.

1. For \(CaCO_3

ightarrow CaO + CO_2\), it is a decomposition reaction.

1. For \(Al_2(SO_4)_3+3BaCl_2

ightarrow2AlCl_3 + 3BaSO_4\), it is a double - displacement reaction (also a precipitation reaction as \(BaSO_4\) is precipitated).

1. For \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O\), it is a combustion reaction (also a redox reaction, similar to cellular respiration).

1. For \(3Mg+Fe_2O_3

ightarrow2Fe + 3MgO\), it is a single - displacement reaction.

1. For \(SO_3+H_2O

ightarrow H_2SO_4\), it is a combination reaction.
