Question
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
Solution
-
Removing seed casings from grains: This is an example of separating. The process involves separating the seed casings from the grains, which are two different components mixed together.
-
A soda bottle bubbling when it is opened: This is an example of separating. When a soda bottle is opened, the carbon dioxide gas that was mixed with the liquid is released, causing the bubbles.
-
A bright copper statue turning green from weathering: This is not an example of mixing or separating. This is a chemical reaction known as oxidation where the copper reacts with the elements in the air and turns green.
-
Removing salt from seawater: This is an example of separating. The process of desalination involves separating the salt from the water.
-
Water decomposing to oxygen and hydrogen: This is an example of separating. Through a process called electrolysis, water can be separated into its two components, oxygen and hydrogen.
