Is wood burning a chemical reaction or a physical reaction?
The burning of a wooden stick is a chemical process.
What do you call substances that are made by a chemical reaction?
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.
When a wax taper is used to light a firework is it a chemical or physical change?
Phisical re action: when the wax turns to liquid when the liquid cools down it turns to solid which goes back to its own form again soryy i don't know the chemical reaction
What goes under no chemical change in a chemical reaction?
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
What is it called when a substance under goes a chemical change?
A chemical reaction occur.
When a flower goes brown is it a chemical or physical change?
The browning of a flower is a chemical change. Color changes are one sign of a chemical reaction.
What matter undergoes a chemical change the composition of the matter?
wow, did you copy this offf of a science worksheet? lol and it is "it changes" and when it goes under physical change "it remains the same"

Is an apple ripening a reversible change or a chemical reaction and why?
Apple ripening is a chemical reactn (new person answering) It is a chemical reaction because when you think about it, an apples ripening only happens once; apple buds on a tree, goes yellow, goes green, goes red-ish, goes juicy red, is either eaten or falls off the tree, goes mouldy and shrivels up. Hope this answer helped and was improved than the other answer! :)
Is there a chemical reaction when a firework goes off?
Yes.
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.
Is heating sucrose a physical or chemical change?
At first it is a physical reaction. If you keep heating it it will undergo a chemical change. In fact, once it melts you have altered its chemical makeup (melting by itself is a physical change but in sugar that also marks a chemical change). Heat more and it undergoes another chemical change and goes from clear to brown another chemical change takes places. Eventually you can drive off (almost) all but the carbon atoms.http://answers.yahoo.com/question/index?qid=20080906171221AAcGFPs
