It is difficult to detect the presence of isotopes in chemical elements during chemical studies because the isotopes are "just like" the other atoms of a given element except for the number of neutrons in the nucleus. That means if you have a two or more isotopes of a given element in a quantity of that element, all the atoms will chemically behave the same way, and you can't "tell them apart" from each other. The tiny difference in the weights is all that distinguishes the isotopes apart in a given element. And it is extremely difficult to separate out the different isotopes of an element. Certainly it cannot be done chemically, as the isotopes are chemically the same, as stated. It falls to physical processes to sort things out, as was done in the case of uranium during World War 2, to obtain 235U from uranium so a fission weapon (an atomic bomb) could be built.
Something needs to be "done" first in order to see the effect of a chemical property. They are not properties that you can immediately see or account for with your senses, tests and experimenting need to be done first. For example, flammability is a chemical property. You cannot observe this by just looking at a substance, tests need to be done. Another is reactivity with other substances. To observe this property, the substance first needs to be introduced to a variety of other chemicals.
Some indicators of a chemical reaction are:
- formation of new compounds - change of color
- change of odor
- release of a gas
- change of the temperature (absorption or release)
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion - sometimes a sound is produced - possible chemiluminescence
isotopes of the same element have nearly identical chemical properties, which makes this type of separation impractical
Excepting hydrogen the chemical properties of isotopes are not special.
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.

Volume is a physical property.
Yes , it should or else it is a physical property
you can observe it without changing it.
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.

no!

physical (because you can observe it without inducing a chemical reaction).

chemical properties
this answer has chemical propertiesnot property....To observe the chemical properties of a substance you must try to change it to another substance.another one is : A chemical property of methane ( natural gas) is that it can catch fire and burn in air.
Volume is a physical property.
