Is dissolving carbon dioxide in water a physical or chemical change?
It's a physical change because carbon dioxide still has it's same properties. It is not changed.Added:Even if you dissolve it in water it is still there thus making it a physical change and not a chemical change. If it were a chemical change then it would be changed for example, fire or burning things like logs and so forth. Dissolving something in water is not changing it completely it only has a minor change in how you see it, thus it is a physical change.The only 'chemical' change might be considered to be the protolysis of water being slightly enhanced by the hydrogen bonding to carbon dioxide molecules. But that is more a (very weak) 'chemical' change of water molecules rather than of CO2 molecules:(CO2)aq + 2 (H2O)l > (Cl-)aq + (H3O+)aq
Is makeup being applied a physical change or a chemical change?
Applying makeup is a physical change.
What is the difference between melting and dissolving?
Dissolving is the chemical state in which melting is physical state but the difference is when you dissolve something some things can be brought back but when you melt some thing you are mostly likely not to bring it back to it's natural form
Is a dissolving zinc in acid a chemical change or physical change?
Dissolving zinc in acid is a chemical change. It really isn't being dissolved, it is reacting with the acid to form new substances. For example, if you react zinc with hydrochloric acid, the products will be zinc chloride and hydrogen gas. The zinc seems to dissolve, but it is actually combining with the chlorine in the hydrochloric acid. Zn + 2HCl ---> ZnCl2 + H2
Is flat tires a sign of physical change or physical change?
Flat tires is a sign of physical change. The tires go from being normal, to then being flat. This changes their physical form.
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 making soap into soap suds a chemical or physical change?
That's a good question, I'm pretty sure that its just a physical change though. I don't think any of the properties of soap are being changed when its dissolved in water. Unless a new compound is being formed between the soap and the water, then its only a physical change. If you don't believe me that a new compound isn't formed, look up dissolving sugar in water. It's pretty much the same idea, and I know for sure that that's counted as only a physical change.
Is mixing sugar in water a physical change or a chemical change?
ANSWER:A physical change. Nothing new is made from the solution and they both can be separated later by using heat to evaporate the water, leaving the sugar behind.
Distinguish between physical and chemical change?
A chemical change is a change involving making and breaking chemical bonds to form new chemicals. For example when wood burns the carbon and hydrogen in the cellulose react with the oxygen in the air, forming carbon dioxide and water. A physical change is one that the chemical changes states and no new chemicals are formed, like melting ice or dissolving salt in water.
Is hanging wet towels a chemical or physical change?
