Which chemical symbols will complete the equation for this single displacement reaction? 2nabr + cl2 → 2 blank blank + blank 2

 The symbols  that will complete the  equation  for single  displacement reaction  is 2NaCl + Br2

Explanation

The  balanced equation is as below

2NaBr + Cl2→ 2NaCl  + Br2

A  single  displacement reaction is type of reaction in which  element  react with  compound  and take place  of other  element  in that compound.

Mostly the  more  reactive  element  displaces  the less reactive elements from its compound.

Chlorine (Cl2) is more reactive than bromine(Br2)   therefore  chlorine  displaces  bromine  from its  compound.

2Na Cl +Br2

Explanation:

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
