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.

∙ 13y agoIndications of a chemical change include a change in color or smell, a release of heat, bubbling and/or precipitation. Any change other than these is unlikely to indicate a chemical change. Of the ones listed, precipitation is the one least observed.
Wiki User
∙ 10y agoGeneral signs that a chemical reaction has taken place are: a color change, a change in temperature, creation of gas bubbles, and formation of a precipitate. Something not on this list, like the change of state or shape is not a sign a chemical change has taken place.

Is bananas turning black if you leave them in a warm cupboard for a week a chemical reaction and why?
Yes, it is a chemical reaction, because the colour of the banana has changed, which shows that a chemical reaction has taken place. Also, if the banana has gone black and turned bad, you can't change it back to it's original form, which proves that it is a chemical reaction and not a physical reaction. Remember - A chemical reaction has definitely taken place if : It's colour has changed A gas is given off There are energy changes Or, it can't be changed back to what it used to be! :) Hope this helps!!

When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
