Balance the following reaction:


A2B + DC3 --> AC + D2B3


Hint: Don't do this in your head. Use a piece of paper and a pencil.


When this reaction is balanced, what number must be to the left of AC?

Respuesta :

kenmyna

 The balanced reaction is   as below

3A₂B  + 2DC₃→ 6 AC  + D₂B₃


The number that must be  to the left of AC   is 6

 Explanation

  • According to the law  of mass  conservation , the number of atoms in reactant side   must be equal  to number  to the number of atoms  in  product  side.
  • Therefore the equation above is balance  since  it obey the law of mass conservation.
  • For example there is 6 atoms  of A in reactant side and  6 in product side.

Answer:

6 is the correct answer
