Question

select all the correct answers. 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

Explanation:

• Removing seed casings from grains: Separates solid components (casings and grains).
• A soda bottle bubbling when opened: Releases dissolved CO₂ gas from liquid, a separation process.
• Removing salt from seawater: Separates salt (solute) from water (solvent) in a solution.
• Copper statue turning green: Chemical reaction (corrosion), not mixing/separating.
• Water decomposing: Chemical decomposition, not mixing/separating.

Answer:

removing seed casings from grains, a soda bottle bubbling when it is opened, removing salt from seawater
