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 are four things that indicate that a chemical change probably happened?
formation of gas, formation of a precipitate, change im color, change in odor
What are examples of solids in a chemical change?
a precipitate.
What is a solid substance that forms when two liquids chemically react?
When one liquid reacts with another it is called a precipitate.
How do you know when there is No Reaction in 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 are four types of evidence that indicate that a chemical reaction may have taken place?
1. A colour change occurs 2. A gas is evolved. 3. A precipitate is formed. 4. A large energy change occurs.

What is an example of the formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.
Is an formation of precipitate an indication of a chemical change?
a
What formation is an indicator of chemical change?
precipitate
What are examples of solids in a chemical change?
a precipitate.
What do you look for in a chemical change?
change in color, formation of gas and precipitate ;))
What type of change occurs in a chemical reaction?
a precipitate is a solid that forms during a chemical reactions
What are the six types of evidence for a chemical change?
Types of evidence for chemical change include: A gas is evolved. A precipitate appears or disappears. Heat may be evolved or absorbed. A color change occurs. A substance disappears.
What are the four occurrences indicate a chemical reaction has occurred?
A chemical reaction can result in any or all of the following: - a change in temperature (up or down) - a change in color - a smell that wasn't there before - the formation of bubbles (indicating the production of a gas) - the formation of a precipitate
