A (they are experimentally determined exponents)
Answer:
They make food by using chemosynthesis.
Explanation:
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.
