question 6
question 6 of 15
______ is a combination reaction.
2nacl yields 2na + cl₂
li + nacl yields licl + na
2na + cl₂ yields 2nacl

Explanation:

A combination reaction is a reaction where two or more reactants combine to form a single product.

• For the reaction \(2NaCl

ightarrow2Na + Cl_{2}\), it is a decomposition reaction (one reactant breaks into two products).

• For the reaction \(Li+NaCl

ightarrow LiCl + Na\), it is a single - displacement reaction (one element displaces another in a compound).

• For the reaction \(2Na+Cl_{2}

ightarrow2NaCl\), two reactants (\(Na\) and \(Cl_{2}\)) combine to form a single product (\(NaCl\)), which is a combination reaction.

Answer:

\(2Na + Cl_{2}\text{ yields }2NaCl\) (the third option)
