What are three clues that a chemical change has occured?
Three clues that a chemical change has occurred:Color changesa precipitate formsa gas forms
What is one of the signs of a chemical change?
There are four common clues to the fact that a chemical change is occurring, though they are not always definitive:a gas is produceda precipitate is formedthere is a colour changethere is a large energy change.
What are 5 clues that a chemical change as taken place?
These are the clues to tell if it's a chemical change or not1. Change in color 2. Energy change (cools, heats, light, sound)3. Gas production4. Odour change5. Precipitate production (eg. 2 liquids forming a solid substance)
What are not clues that a chemical reaction has taken place?
Phase changes are one example of a non chemical change. If the substance reacts the same way chemically, it has the same properties such as melting point, there has not been a chemical change.

What are the five clues that suggests a chemical reaction is taking place?
first when there's a physical change in the substance second there will be a solution or a formula to that substance third is, it involves temperature fourth is change in color of the substance fifth is the bubbling of another substance is yet an another clue that a chemical reaction has occured.

Are the clues that indicate a chemical change always reliable?
While clues like color change, gas production, and temperature change are common indicators of a chemical change, they are not always reliable on their own. It is important to consider these clues in the context of the specific reaction taking place and to look for multiple signs to confirm a chemical change has occurred. Testing with chemical indicators or analyzing the reaction using scientific techniques is often necessary for a more definitive answer.
What are three common clues that chemical change has occurred?
precipitate forms, color change, heat and light is given off, gas is formed usually hydrogen or co2
