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
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 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
Is sand and dirt mixed a chemical or physical characteristics?
it is a physical change
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.
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.
What are the characteristics of a chemical reaction with example?
A chemical reaction involves the breaking and formation of chemical bonds between atoms to create new substances. Some characteristics include the reorganization of atoms, the release or absorption of energy, and the formation of new chemical properties. For example, when hydrogen gas reacts with oxygen gas to form water, new chemical bonds are formed and energy is released in the form of heat and light.
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.
What are some chemical characteristics of xenon?
Reacts with Oxygen and Fluorine
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).
