Mixing iodine and baking soda is a physical change because the substances are simply being physically combined without forming any new substances.
Mixing baking soda with iodine solution would not cause a chemical change. It would be a physical change where the substances are still present as they were before mixing, and they can be separated.
Mixing water with baking soda is a physical change as it does not alter the chemical composition of either substance. The water may dissolve the baking soda, creating a solution, but the individual molecules of water and baking soda remain the same.
chemical. when a reaction is undertaken that changes the structure of a substance and creates a new substance it is a chemical reaction. a gas is created during the reaction and a new chemical compound (sodium acetate) is left behind leaving neither of the previous elements present.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
It is a chemical change
Mixing flour and baking soda is a physical change; the process of mixing them together does not in itself cause them to change into any other chemical. However, when the pastry is baked, then there will be chemical changes.
Mixing iodine and baking soda is a physical change because the substances are simply being physically combined without forming any new substances.
mixing baking soda with water is a physical change b/c you don't change the chemical structure mixing baking soda with vinegar is a chemical change b/c you change the chemical structure ================= It is definitely a chemical reaction resulting in a chemical change.
physical because its a mixture and doesnt chemically combine
Mixing baking soda with iodine solution would not cause a chemical change. It would be a physical change where the substances are still present as they were before mixing, and they can be separated.
chemical
Mixing a cake is a physical change, not a chemical change. In this process, the ingredients physically combine but do not undergo a chemical reaction to form new substances. The mixing can be reversed by separating the ingredients, unlike in a chemical change where new substances are formed.
Mixing water with baking soda is a physical change as it does not alter the chemical composition of either substance. The water may dissolve the baking soda, creating a solution, but the individual molecules of water and baking soda remain the same.
No.
