What changes gives NO evidence that a chemical reaction has taken place?
Changes such as a change in state (solid to liquid), change in color, change in odor, change in solubility, or change in temperature do not provide direct evidence that a chemical reaction has occurred. These changes can be indicative of a physical change rather than a chemical change. To confirm a chemical reaction, additional evidence such as the formation of new substances, evolution of gas, or consumption of reactants is necessary.
Examples of properties are color and odor?
Yes, color and odor are examples of physical properties. Color refers to the way an object reflects light, while odor describes how something smells. These properties can help to identify and classify different substances.
Is odor a physical or chemical property?
Physical.Added:Odor is by many considered as chemical interaction with nasal odor receptors, though this is still under dispute.I, personally, would be more of the 'physical' odor perception, because the odor-creating molecules (eg. in perfume) do not change at all while being 'percepted' in your nose.However there are also undoubtly pure chemical odor perceptions, like those of (gaseous) 'acids', 'ammonia', 'formalin' and hydrogen sulfide.
Is cutting up a pear a chemical reaction?
No, cutting up a pear is a physical change, not a chemical reaction. Chemical reactions involve the breaking and forming of chemical bonds to create new substances, while cutting a pear only changes its physical appearance.
Is sugar dissolving in water a chemical reaction?
No, it is a physical change. A chemical reaction involves changing a molecule(s) into something else. When dissolving sugar in water, you still have sugar and you still have water.
Is odor physical or chemical?
it is a chemical component which gives bad odor
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
Is a odor a physical or chemical change?
AnswerNeither. Odor is not a change at all. Odor is airborne molecules that have a particular smell. A change is a process and odor is not a process. The things which cause odors can be either physical or chemical. For instance, the body odor is caused by chemical changes, but if you open jar of a smelly chemical, that is a physical change (some of the molecules of the chemical are evaporating and are thus airborne).When talking about mixing chemicals and substances, a change in odor is a chemical change.(I assume this is what you meant when you asked is odor a chemical or physical change)
Is pungent odor a chemical solution or physical?
Physical
Is heat light and change in odor indicate a physical change?
Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.
Is Pungent odor a physical or chemical change?
Pungent odor is a physical change because it only affects the sense of smell without altering the chemical composition of the substance emitting the odor.
Is a skunk producing odor physical or chemical change?
The skunk producing odor is a chemical change because it involves a reaction within the skunk's body that results in the release of specific compounds that create the distinctive smell. This process alters the chemical composition of the skunk's secretion, leading to the odor being produced.
Is odor a chemical or a physical?
Odor results from chemical reactions. Sensors in your nostrils bind with specific compounds in the air to detect scents. But this is not to be confused with the fact that odor is a physical property.
What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.
Is dissolving a physical or chemical reaction?
a physical reaction for the chemical structure is not changing.
Is it a chemical or physical reaction?
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
Are properties such odor color density and solubility physical or chemical properties?
Color and density are physical properties. Odor and solubility are chemical properties.
