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

- formation of new compounds

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


How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?

For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.


What are three indicators of a chemical reaction occurring?

there are mainly two ways that indicate that a chemical change has taken place. These ways are the physical properties (the way things look, without changing the chemical makeup of a substance) are different, and the chemical properties (the way the substance reacts with other substances) are different.


When two substances are mixed they might form a new substance What would indicate that a new substance has been formed?

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 - formation of new compounds


How would you determine if a chemical change has occurred?

There are a few ways... 1) the identity of the substance changed 2) there was a gas released (fizzing, bubbles, etc.) 3) color change (even though color change is a physical property, it might be caused by a chemical reaction)

There are 92 naturally occurring what?

You might be referring to the chemical elements. However, we are now aware that there are 96. For more information you might wish to consult the wikipedia page about chemical elements.

The heating itself is a physical change, a chemical change might come from the heating, however.
