Why does this indicate that a chemical reaction might have occurred?
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 chemiluminiscence
What evidence demonstrates that a chemical change has taken place?
You might observe a change in color, gas bubbles being formed, a change in temperature (this might require the use of a thermometer, unless the solution actually boils), or you can test for a specific chemical by using an indicator, or analyse the solution by means of a mass spectrometer. Explosions are also a very convincing form of evidence that a chemical change has taken place.
What kind of physical evidence might be observed what would indicate that chemical reaction occurred?
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
The production of light when two substances are mixed might indicate that?
a chemical reaction is occurring between the two substances. The release of light is often a sign of energy being produced as a result of the reaction.
Give three things you might see if a chemical reaction takes place?
There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.

How would you determine if a chemical change has occurred?
You can determine if a chemical change has occurred by looking for signs such as a change in color, formation of a precipitate, evolution of gas, or release of heat or light. Additionally, if the chemical composition of the substance has been altered, it is likely that a chemical change has taken place.

Is sound a physical or chemical change?
water boils, it make sound. is that a chemical change??? P.S why use wikianswer?
What effect does water have on bones?
the bone does not change that much it might gust change color
What would indicate that a chemical change might be occurring -Apex?
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 is the only way to confirm that a chemical change has taken place?
To be certain that a chemical change has taken place you check the composition of the sample before and after the change. The following is a chemical property of water at 4 C is its ability to decompose into hydrogen and oxygen.
Is oxidation a physical change?
Oxidation typically involves a chemical change where a substance loses electrons. While you might observe physical changes associated with oxidation, such as a change in color or texture of the material, the process itself is primarily a chemical change.
