  Mg  + Fe2O3→ Fe  +mgO  

The  coefficients needed to balance the reaction above is  3, 1,2,3  

the  reaction  is a single  replacement reaction/ single displacement  reaction

 The balanced  equation is is therefore

 = 3Mg + Fe2O3 → 2Fe  + 3MgO

  • The equation  above is  balanced  since it obey the law of mass conservation. that is the number  of atom  in side of  reactant is equal to number of atoms  in product side.
  • for example  there is  3 atoms  of Mg  in reactant side  and 3 atoms of Mg  in product side.

 The  reaction is  a single replacement  reaction  because  Mg replaces Fe  from  its  compound.

K₂O +2Li Li₂O +2k how do you solve?
tiny-mole [99]

Answer:

K₂O +2Li --> Li₂O +2K

Explanation:

On the left side, K has 2 atoms and O has one combines with Li having 2 atoms. When the process starts Li burns and got atoms from O.

Hence O has 2 ions and Li has 1 ion

so to complete the bond, Two Li will have 2 ions which can complete O by sharing his 2 icons. i.e. Li₂O

and Two atoms of K can exist like 2K

So the equation will be like

K₂O +2Li --> Li₂O +2K
