which of these are examples of mixing and separating? removing seed casings from grains a soda bottle bubbling when it is opened a bright copper statue turning green from weathering removing salt from seawater water decomposing to oxygen and hydrogen
Answer
Brief Explanations:
- Removing seed casings from grains is a physical separation process.
- A soda bottle bubbling when opened is carbon - dioxide gas separating from the liquid soda (a form of separation).
- A bright copper statue turning green from weathering is a chemical reaction, not mixing or separating.
- Removing salt from seawater is a separation process (e.g., through evaporation).
- Water decomposing to oxygen and hydrogen is a chemical reaction, not mixing or separating.
Answer:
- removing seed casings from grains
- a soda bottle bubbling when it is opened
- removing salt from seawater
