Expert Answer

Step 1

A balanced chemical equation or reaction is the one in which the total number of atoms for each element in the reactant side (left hand side) is equal to the total number of atoms for each element in the product side (right hand side).

The simple steps to balance a chemical reaction are:

  1. Write down your given equation.
  2. Write down the number of atoms per element.
  3. First start balancing with single elements, other than hydrogen and oxygen atoms.
  4. Use a coefficient to balance the single elements.
  5. Balance the hydrogen atoms next.
  6. Balance the oxygen atoms at last.
Step 2

Sb + Cl2 → SbCl3

This equation can be balanced as follows:

Firstly, balancing of Cl atoms can be done by adding co-efficient 3 with Cl2 and 2 with SbCl3 .The equation becomes:
