Yes, adding calcium to water is a chemical change. The following equation represents the reaction between calcium and water.
Ca + 2H2O ---> Ca(OH)2 + H2
Well, honey, when you mix lemon juice with limestone, you're causing a chemical reaction that breaks down the calcium carbonate in the limestone. This reaction forms calcium citrate, carbon dioxide, and water, which is definitely a chemical change. So, yes, adding lemon juice to limestone is a chemical change, no ifs, ands, or buts about it.
Well, isn't that just a happy little question! When calcium dissolves in water, it's actually a physical change because no new substances are formed. The calcium is just breaking apart into its ions, creating a solution that still contains the same calcium atoms. Just like adding a touch of blue to our sky, it's all part of the natural beauty of chemistry.
Yes, adding lime (calcium hydroxide) to baking soda (sodium bicarbonate) results in a chemical change known as a double displacement reaction. The reaction forms water, sodium hydroxide, and calcium carbonate.
When you add calcium to water, it forms calcium ions (Ca2+) in the water. This results in a mixture of calcium ions in water. The calcium ions and water molecules remain separate entities rather than bonding to form a compound.
Dissolving calcium in water is a physical change because the chemical composition of calcium does not change during the process. It is a reversible process, and the calcium can be retrieved by evaporating the water.

its not a chemical change because you can take the oil in

The chemical compound found in slaked lime is calcium hydroxide, which is produced by adding water to calcium oxide (quicklime). It is commonly used in construction, agriculture, and water treatment applications.
This is a physical process.
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
