Answer:
it is because they are placed geographically different.
Answer:
C₁₆H₃₂O₂ (s) + 22O₂(g) → 16CO₂(g) + 16H₂O(g)
Explanation:
In order to determine a combustion reaction we should know that:
Reactants are: X compound and O₂
Products are: CO₂ and H₂O
In this case, the X compound is the solid palmitic acid: C₁₆H₃₂O₂
The balanced equation will be:
C₁₆H₃₂O₂ (s) + 22O₂(g) → 16CO₂(g) + 16H₂O(g)
