Mixing Alka-Seltzer and water is a reversible change because it can be undone by allowing the water to evaporate, leaving behind the original substances in their initial forms.
reversible
No, mixing cement and water is not a reversible process. When water is mixed with cement, a chemical reaction occurs that leads to the hardening of the mixture into concrete. This change is not easily reversible without significant effort and resources.
Mixing cement and water is a reversible change because the two substances can be separated by allowing the water to evaporate, leaving the solid cement behind. This process does not alter the chemical composition of either the cement or the water.
No, a lava lamp is not a reversible change. The melting and mixing of the wax and oil inside the lamp is a physical change that cannot be easily reversed to its original state.
Rusting of iron is considered irreversible because once iron undergoes oxidation in the presence of oxygen and water, it forms iron oxide (rust) which cannot be easily converted back to pure iron. The process of rusting is a chemical reaction that changes the chemical composition of iron, making it difficult to reverse the process without specialized treatments.

Sugar and Salt
It is reversible. You can allow the water to evaporate, leaving the salt behind.

No because you can't get the vinegar back to it's original state because some of the bacteria has gone inside the milk

Yes, mixing gases is a reversible change because it can be easily undone by separating the gases through processes like filtration or distillation. The individual gases retain their properties and do not chemically combine when mixed, allowing them to be separated efficiently.
Mixing lemon juice and baking soda results in a chemical reaction that produces carbon dioxide gas, water, and sodium citrate. This reaction is irreversible as the original substances are transformed into new substances with different properties.
