No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
no it isn't. My 6th grade teacher told me that and i still don't really understand it.
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
The instant coffee and the water have not changed chemically or physically. It becomes a mixture, not a solution; the water is separate from the coffee powder. Therefore it is not a physical change.
Dissolving in water is a physical change.
no it isn't. My 6th grade teacher told me that and i still don't really understand it.
Dissolving sugar in hot water is a chemical change.
Because making gravy merely involves dissolving the powder in water, it is classified as a physical change. This is due to the fact that neither the powder, nor the water are undergoing and change in chemical properties.
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
It is a physical change.
A match burning is a chemical change. Salt dissolving in water is a physical change.
Dissolving in water is a physical change.
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
Yes. Dissolving drink mix does not change its chemical composition.
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
Dissolving is a physical process.
