I think you want to ask the complete ionic equation and net ionic equation. For complete ionic equation: 3Ba2+ + 6Cl- + 2Al3+ + 3SO42- -->3BaSO4 + 2Al3+ + 6Cl-. For net ionic equation: 3Ba2+ + 3SO42- -->3BaSO4.
Answer:

Explanation:
The chemical formula for methane is 
The chemical formula for oxygen is 
The chemical formula for carbon dioxide is 
The chemical formula for water is 
Methane burns in oxygen to give carbon dioxide and water:

The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:
