1. BaCl2+K2SO4⇒BaSO4+KCl

2. Na+FeCl3⇒Fe+NaCl

Further explanation

Given

Word equation

Required

Skeleton equation

Solution

A chemical reaction can be expressed in terms of:  

  • words equation
  • the skeleton equation  
  • balanced equation

The skeleton equation is still in unbalanced form  

So only chemical formulas of reactants and products and the relative amounts of the reactants and products are not included

For example :

• word equation

Ethane + Oxygen ⇒ Carbon dioxide + Water

• skeleton equation

C₂H₆ + O₂ ⇒ CO₂ + H₂O

• balanced equation

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
