Is mixing coca powder with water a physical or chemical change?
Wnebw
To call it an physical or chemical change, we first need to describe both of them briefly.
A physical change is the one which does not change the chemical properties of a substance.
A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here.
So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples)
However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)

Mixing lemonade powder into water is a chemical change. This is because the powder changes the water molecules and can not be taken out.
Is making gravy a physical or 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.
Is it correct to say that dissolving a packet of juice powder in water makes a new substance such as fruit punch so it must not be a physical change?
The change is a physical one because the powder is simply dissolving into the water, and it could be powdered again by removing the water again. The physical properties of the fruit punch are very different, but not a chemical change unless there is a new substance created or precipitated.
Give me an example of experiment?

What happens when plaster of Paris mix with water?
Plaster of Paris is formed from gypsum. The gypsum is heated to 150 decrees Celsius and becomes a dry powder. When this powder is mixed with water it re-forms into a paste and eventually hardens into a solid. The powder mixed with water is held together by hydrogen bonds in the water molecules. This is a week bond that is easily broken. When Plaster of Paris and water are mixed together they undergo a chemical change. The particles rearrange to make a completely new substance. When plaster of Paris and water are mixed together the mixture becomes warm releasing energy in the form of heat therefore undergoing a chemical change.

Is liquid and powder mixing in soda bottle a physical or chemical change?
1. Any chemical reactions - a physical phenomenon.2. Mixing when chemical reactions are implicated - chemical change (depending on the type of the liquid and powder).
Is mixing lemonade powder into water a physical change?
If you are talking about adding a pack of powder to some liquid then this is a physical change. The powder is being dissolved in the liquid and therefore undergoing a change of state, this is however reversible by evaporating the liquid of to leave you with a solid mass (the original powder just not broken up)
Is mixing baking soda and vinegar a chemical or physical 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.
Is mixing 2 chemicals a white powder forming chemical change?
Any chemical reactions - a physical phenomenon. To discuss a chemical change please mention the two chemicals.
Is baking soda losing mass when heated a chemical or physical change?
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.
