The process involving separation of liquid/solid mixture as regards this question is Decantation.
- Decantation can be regarded as one of the process used in separation of liquid from solid as well as other immiscible (non-mixing) liquids through the removal of the liquid layer that is present at the top from the layer of solid/liquid which present at the below.
- In the process, the liquid will be poured slowly into another vessel as the pouring continues, then the solid will settle in the original vessel.
- This process can be done through tilting the mixture after the the top layer have been poured out.
<em>Therefore, decantation is one of the separation technique.</em>

Answer:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).
Explanation:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
2H₂O(g) → 2H₂O(l)
- To add the two equations: we omit H₂O(g) that is formed by 2 moles in the product side of the first equation and consumed by 2 moles from the reactants side in the second equation
- So, the overall chemical equation is obtained by combining these intermediate equations is:
<em>CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).</em>
