How could you prove that dissolving table salt in water is a physical change or not a chemical change?
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
What else can I help you with?
How could you decide whether the dissolving of sugar in water is a physical or chemical change?
You can evaporate the water and recover the sugar unchanged. A chemical change means a chemical reaction has taken place and changed the substance chemically. A physical change means that a solid has become a liquid such as dissolving sugar.
Is dissolving salt in water a physical or chemical change and why how could you verify your answer?
Dissolving salt in water is a physical change because it does not alter the chemical composition of either the salt or water molecules. This change can be verified by allowing the water to evaporate, which would leave behind the original salt crystals without any chemical changes occurring.
Is burning a log a example of chemical or physical changes?
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Is making salt water a physical or chemical?
Could be either or both. Depends on the method used to purify the water. If you use reverse osmosis or distillation, it would be physical. If the water is treated with chlorine, it would be chemical.
What is the différence between a chemical change and a physical change?
physical changes are thing you can see (note a change in color could be a percipatate forming) chemical release energy in some way shape or form or it could form a perciapte which you can't see through
How could you prove to someone that the dissolving was a physical to change not a chemical change?
You can demonstrate that dissolving is a physical change by showing that the chemical composition of the substance remains the same before and after dissolving. This can be done by evaporating the solvent and obtaining the original substance in its solid form. Chemical changes involve a change in the chemical composition of the substances involved, leading to the formation of new substances, which is not the case in dissolving.
How could you prove to someone that the dissolving of table salt was a physical change not a chemical change?
The chemical formula of sodium chloride is not changed by dissolution.

Is the dissolving of sugar in water a physical property?
No, it is a chemical change. A physical change would be for instance a wooden plank, if yoiu took that wooden plank and broke it in half it would still be a wooden plank with the same properties, the only things that changed is its shape. Your sugar in water could not be seperated back out because it has dissolved into the water and now has different properties.
Is tarnisha physical change or chemical change?
Well it could either be a physical change OR a chemical change. .
Does physical change occur when epsom salt is dissolved?
Yes. The way I think about it is if you can change it back (in this case, you could filter the epsom salt out, or evaporate the water, drying it) then it is a physical change.
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.
Is dissolving a solid a physical or chemical change?
it depends on if the solid is also water. if they are both water then its a physical reaction because it just changes the state of matter. if the solid isn't water then its chemical because the two substances then transform into one new substance.

Is Stomach acid dissolving pizza a physical or chemical change?
There are some chemical aspects:base is made from flour and yeast,so the reaction between them is a chemical change.The cooking of the pizza is also a chemical reaction, because it cannot be undone.There are also some physical aspects, e.g.Making the doughgrating the cheesemelting the cheese
Is a log burning a chemical or physical change?
Chemical change, because it is irreversible. The chemical composition of the substance actually changes. A physical change is a change of state, like water to ice. There, H20 is still H20.
