What is the substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
A is a substance that can make something happen faster but is not changed itself?
the answer is a catalyst
Is it true that a substance produced during a chemical change cannot easily be changed back into the original substance?
generally no, but sometimes yes. if one or more of the products is insoluble or otherwise removes itself from the other products, then the reaction is considered irreversible.
Can a substance produced during a chemical change be easily changed back into the original substance?
No they cannot. Chemical changes never ever go back.
Are enzymes permanently changed in the chemical reactions they aer involved in?
No, enzymes are not permanently changed in the chemical reactions they are involved in. Enzymes are catalysts that facilitate chemical reactions by lowering the activation energy, and they remain unchanged after the reaction takes place. They can be used repeatedly in multiple reactions.
What is a substance that speeds up a chemical reaction without permanently being changed itself?
A catalyst.
Can an element be changed into a simpler substance?
Only in a nuclear reaction, otherwise no.

When a substance has the ability to participate in a chemical reaction what is it called?
It is called a reactant. While catalysts participate in reaction dynamics, they are not permanently changed in the process.
How long does a cell remain formatted in Excel?
It will stay formatted until the formatting is changed to something else, so it can in effect have the same format permanently if it is not changed.
What does varible mean?
A variable is something that may be changed or manipulated during a experiment.
What alters a substance into another?
Heat can alter a substance into another substance. Such as when you bake a cake the batter is changed into a cake and can not be changed back.
What is the difference between a phisical change and a chemical change?
A physical change is one you can see. It changes the size, shape, or color of something. A chemical change is one that changes the composition of something. Basically, when a substance is changed into a different substance.
Is it true that Enzymes are permanently changed by the reactions they catalyze?
true
Are enzymes permanently changed in the chemical reactions they are involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
