precipitate forms, color change, heat and light is given off, gas is formed usually hydrogen or co2
Some clues to tell if the change is chemical:
It might be emitting smoke, it could be fizzing or bubbling, the color could have changed or the substances have burned. There's 4 for you. Come up with some on your own, too. It will improve your knowledge on how the world works.
Changes in color, temperature changes (heat absorbed/released), and changes in chemical reactivity are all indicative of a chemical change.
There are possibilities. Here are three common ones.
1. color change
2. change in temperature (can be warmer or colder)
3. formation of a precipitate
FOUR clues that a chemical change has occurred are a temperature change, formation of gas (usually CO2), formation of precipitate (solid), and a color change.
change in color
change in temperature
gas released
Three clues that a chemical change has occurred:Color changesa precipitate formsa gas forms
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.
list four possible clues to a chemical change
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

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.

Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
