It all depends on what chemicals you are using. For example, if you were using sulfur & carbon, either one could be changed.
A substance that undergoes change in a chemical reaction is called a reactant.
chemical reaction is when a substance is changed chemicaly but not physicaly
You think probable to the reactants.
Substances are changed only after the beginning of a chemical reaction.
These are called catalysts.
These are called catalysts.
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.
A catalyst.
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
The compound word 'chemical property' is a noun, a word for the characteristic of a substance observed during a reaction in which the chemical composition or identity of the substance is changed; a word for a thing.
A chemical reaction means that when it has turned into the new substance it cannot be changed back. Once the compost has rotted it can't be changed back into eg: carrot shavings.
