Answer:
Cl2 + 2NaBr --> 2NaCl + Br2
Explanation:
This is a single displacement reaction where one side of the ionic compound switches with the other.
So, Cl2 + NaBr ---> NaCl + Br2
This isolates the Bromine and puts the Chlorine in it's place.
Then, balance out the equation like so and you should get
Cl2 + 2NaBr --> 2NaCl + Br2
Its relative density causes objects to float or sink.
If the density of the substance is greater than the substance it is in, it will sink.
If the density is less than the substance it is in it will float.
The correct answer is aerobic cellular respiration. This process uses glucose and oxygen as reactants producing six molecules carbon dioxide, 6 molecules water and 30 molecules of ATP which is used directly to produce energy.
