Oil, natural gas, and coal are not examples of sustainable resources because they are finite and non-renewable sources of energy. Once these resources are extracted and burned, they cannot be replaced within a human lifetime. Additionally, the extraction and burning of these fossil fuels contribute to environmental degradation and climate change. Therefore, relying on these resources for energy production is not sustainable in the long term. **

A separating funnel is a laboratory apparatus used to separate immiscible liquids or liquids with different densities. It consists of a conical-shaped container with a stopcock at the bottom. When the mixture of liquids is poured into the funnel and allowed to settle, the stopcock is opened to release the lower layer of liquid, while the upper layer remains in the funnel. This process allows for the efficient separation of the two liquids based on their density. **
