What else can I help you with?
Can the chemical properties of a substance be observed without changing the substance?
physical properties
What are some physical and chemical properties of paper that can be observed?
it white and its soft
Are isotopes different in terms of their chemical properties?
A difference of chemical properties is observed for light elements; for other elements these differences are extremely small.
What properties can be observed during a chemical reaction?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence -formation of new compounds
What property of matter that can be observed and measured without changing the composition?
chemical properties.
What condition can chemical properties be observed?
Chemical Properties can be observed only when substances in a sample of matter are changing into different substances.
What chemical properties that can be observed?
every thing around you.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
When can chemical properties be observe?
chemical properties can be observed only when the substances in a sample of matter are changing into different substances
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Chemical properties observed only when a substance undergoes a chemical change a true bfalse?
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
Why did Mendeleev called his arrangement of elements the periodic table?
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.
Can chemical properties cannot be observed without changing the substance?
yes
What are some physical and chemical properties of paper that can be observed?
it white and its soft
How is physical properties different from chemical properties?
Physical properties are characteristics of a substance that can be observed or measured without changing its chemical composition, such as color, density, melting point, and boiling point. In contrast, chemical properties describe how a substance interacts with other substances and involve changes to its chemical structure, such as reactivity, flammability, and acidity. Essentially, physical properties can be observed without altering the substance, while chemical properties are revealed during chemical reactions.
Are isotopes different in terms of their chemical properties?
A difference of chemical properties is observed for light elements; for other elements these differences are extremely small.
What Properties Can Be Observed Without Changing A Substance's Chemical Compositionion.?
Physical properties such as color, odor, density, melting point, boiling point, and solubility can be observed without changing a substance's chemical composition. These properties depend on the structure and arrangement of the molecules within the substance and can be measured or observed through physical means.
