One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.

Which statement describes a chemical property that can be used to distinguish between compound A compound B?

One chemical property that can be used to distinguish between two compounds is their reactivity with a specific reagent to form a unique product. For example, if compound A reacts with a specific metal to form a colored precipitate while compound B does not, this difference in reactivity can be used to distinguish between the two compounds.


Chemical test that will distinguish between benzoic acid and phenyl the test must have an abvious physical change?

One way to distinguish between benzoic acid and phenyl is by performing a sodium bicarbonate test. When sodium bicarbonate is added to benzoic acid, it will effervesce and produce bubbles due to the release of carbon dioxide gas. However, no such effervescence occurs when sodium bicarbonate is added to phenyl. This difference in bubbling can be observed as an obvious physical change to distinguish between the two compounds.


What is the difference between a chamical and physical change?

A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.


Can you tell whether a substance is an element or compound based on physical appearance?

No, you cannot determine whether a substance is an element or compound based solely on its physical appearance. Elements and compounds can exhibit a wide range of physical appearances, so other methods are necessary to distinguish between them, such as chemical analysis or examining their chemical formulas.


What is a simple chemical test to distinguish between bezene and hexane answer?

One simple chemical test to distinguish between benzene and hexane is the Bromine test. Benzene will not react with bromine in the absence of a catalyst, while hexane will readily react with bromine to form a colorless product.

What are some steps to physical and chemical change?

Physical change involves a change in the form or state of matter without changing its chemical composition, such as melting ice to water. Chemical change involves a change in the chemical composition of a substance, resulting in new products being formed, such as burning wood to produce ash and smoke. Observing changes in properties, such as color, odor, or temperature, can help distinguish between physical and chemical changes.


What is the difference between chemical change and physical change?

the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.

What methods do scientist use to determine if it is a physical or chemical change?

Scientists distinguish between physical and chemical changes by examining if the change affects the chemical composition of the substances involved. Physical changes alter the appearance or state of a substance without changing its chemical makeup, while chemical changes result in the formation of new substances with different chemical properties through chemical reactions. Techniques such as observing color changes, production of gas, formation of a precipitate, or changes in temperature can help scientists identify whether a physical or chemical change has occurred.


Differences between chemical and physical change?

A chemical change results in a change in chemical composition, while a physical change does not.
