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?(use numerals such as 1, 2, or 3; not words such as one, two, or three)

  The  balanced   reaction is as below

3A2B  +2DC3 → 6 AC + D2B3

Explanation

According to the law of mass  conservation  the   number of  atoms   in the reactant  side must be equal  to  number of atoms  in  product  side.

putting  coefficient  3   in  front  of  A2B, 2 in front DC3 and 6  in front of AC  balance  the equation , since the  number  of atoms is equal in both side.

for  example  we  have 3 atoms of A   in   both reactant  and    products side.

idk i’m struggling too
