Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
Which type of chemical and physical changes you observe in daily life?
Well a Chemical change means that what ever changes can't change back. For example if u have normal paper then burn it that's a chemical change and that's why a chemical change is so important.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
To prove that the burning of a candle is a physical and chemical change, you can observe the physical changes such as the melting of the wax and the formation of soot. Additionally, you can analyze the chemical changes by noting the production of carbon dioxide and water vapor during the combustion process. By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
Is oxidation a physical change?
Oxidation typically involves a chemical change where a substance loses electrons. While you might observe physical changes associated with oxidation, such as a change in color or texture of the material, the process itself is primarily a chemical change.
Is water freezing at 0 degrees a chemical property?
No, water freezing at 0 degrees is a physical property, not a chemical property. This change in state from liquid to solid is a result of the temperature of the water reaching a certain point, and does not involve any chemical reactions.
Chemical or physical something you can observe?
Physical changes are those that can be observed.
Is yellow solid physical or chemical property?
physical (because you can observe it without inducing a chemical reaction).
What are chemical properties harder to observe than physical properties?
they are harder to observe because youcan't be seen.
Is volume a physical property or chemical?
Volume is a physical property.
What chemical and physical weathering do you observe in your home and campus Describewhat happens to the object?
itjj
Must a new substance be formed when you observe a chemical property?
Yes , it should or else it is a physical property
. To categorize the elements what reactions did Mendeleev observe?
These are of course chemical reactions, for example oxydation.
What is the difference between chemical property and physical property?
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.

Is it true Chemical properties aren't as easy to observe as physical properties?
Yes, physical are on the outside and can be observed in a matter of seconds, whereas chemical properties have to be tested, which can take as long as years
