When do you say that a change is chemical?
A chemical change has occurred when a new substance is formed. Characteristics of this include a color change, precipitate is formed or it bubbles meaning a gas has formed.
What clues can you use to identify a chemical change?
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
How would you determine if a chemical change had occurred?
Some characteristics of a chemical change are: - change of smell - change of color - release of gases - change of temperature - formation of a precipitate - change of the aspect - change of pH in solutions - change of viscosity - flames or explosion etc.
How are chemical properties different from chemical changes?
The difference between a chemical property and a chemical change is that the change is how the property of the chemical changes when it undergoes a chemical reaction.
What are characteristics of a chemical change when you mix solids and liquids?
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 are some characteristics of chemical change?
A characteristic of a chemical change is a change in odor. Another characteristic is a change in the temperature. Another characteristic is the creation of a precipitate. Those are just some characteristics.

Is sand and dirt mixed a chemical or physical characteristics?
it is a physical change
When do you say that a change is chemical?

Is putting color to icing chemical or physical change?
Coloring causes only a physical change to icing because it does not alter the chemical characteristics of the icing.
What clues can you use to identify a chemical change?
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
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.
How would you determine if a chemical change had occurred?
Some characteristics of a chemical change are: - change of smell - change of color - release of gases - change of temperature - formation of a precipitate - change of the aspect - change of pH in solutions - change of viscosity - flames or explosion etc.
What is the differences between chemical and physical change?
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
How are chemical properties different from chemical changes?
The difference between a chemical property and a chemical change is that the change is how the property of the chemical changes when it undergoes a chemical reaction.
What are some Chemical reactions with more than 1 characteristics in common?
One example is- H2 + o2 + heat = h2o It is showing 2 characteristics, change in temperature and change in state
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
