Cl2(g) + 2nabr(aq) 2nacl(aq) + br2(l) the reaction given above is a single replacement reaction because: a. one of the reactants is a gas b. none of the reactants are solids c. chlorine replaces bromine d. the reaction proceeds spontaneously

C. chlorine replaces bromine

Explanation:

A single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

This is a single replacement reaction in which chlorine replaces bromine from its aqueous solution. As chlorine is more reactive than bromine , it easily accepts electrons to convert to in and in donates electrons to form .

The reactant chlorine is in gaseous state, is in aqueous state. the product is in aqueous state and bromine is in liquid state.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

it's all four options.
