Question

Fill in the coefficients that will balance the following reaction: a0SrCl2 + a1Li3PO4 → a2Sr3(PO4)2 + a3LiCl

Answer 1

 aoSrCl2 + a1 Li3PO4 → a2Sr3(PO4)2  + a3 LiCl

The coefficients that will  balance  the  equation    above  are

ao= 3

a1=2

a2=1

a3=6

 explanation

•  The  balanced  equation is therefore as  below

           3SrCl2 +2Li3PO4→ Sr3(Po4)2  + 6 LiCl

•  3  moles  of  SrCL2  react with  2 moles of Li3PO4  to  form  1  moles  of Sr3(PO4)2   +  6  moles of  LiCl

 The balanced equation obey law of mass  conversion  of a chemical  reaction since the mass  of the product is equal to mass  of reactant.

• for  example  in reactant  side we have  3  Sr  which is the same in product side.
