What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What is a substance that speeds up a chemical reaction but does not change it self?
catalyst
How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
What is parent material?
The term "parent material" is generic and it refers to any type of substance or material which undergoes some process to produce another material. The term "parent material" can be used in geology, chemistry or radioactivity for three of many examples. In Earth science and geology , it may refer to mineral composition that weathers easily can produce more soil, for example. In nuclear physics, it is the radioactive material that decays to produce daughter nuclei. In chemistry, it is material that undergoes chemical change to yield another chemical.
What chemical change occurs when a more reactive substance replaces a less reactive substance in a compound?
It is a single replacement (displacement) reaction.For example: Does the following reaction occur?Al(s) + CuSO4(aq) --> Al2(SO4)3(aq) + Cu(s)According to the metal reactivity series, aluminum is above copper on the list, so it is more reactive and will replace (displace) copper in the copper sulfate solution. So this reaction will occur.
A substance that undergoes change in a chemical reaction is called a what?
A substance that undergoes change in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products through the rearrangement of atoms.
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
What is a substance that is changed in a chemical reaction Called?
A substance that undergoes change in a chemical reaction is called a reactant.
A substance that undergoes a change in a chemical reaction?
A reactant
When a substance changes to form a new substance with new properties it undergoes a what change.?
New substances are formed when matter undergoes a chemical reaction.
What is a substance that undergoes change in a chemical reaction?
These substances are called reactants.
Chemical properties observed only when a substance undergoes a chemical change a true bfalse?
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
What happens when a pure substances undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped

How can volume change if a substance undergoes a chemical change?
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
Is burning oil a physical change?
No because combustion is a chemical reaction. Anything having to do with burning undergoes chemical change. This creates a new substance therefore creating a chemical change.
What is its does not change by a subastance undergoes a physical change?
The chemical composition of a substance does not change when it undergoes a physical change.
