What are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
Is the rotting of compost a chemical reaction?
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.
Is this true in a chemical reaction the substances that interact are called the products?
No. these are the reactants, the products are what are produced by the reaction.
What happens when a physical reaction occurs?
For example, the change in the state of matter.
This is not lost in a chemical reaction?
Mass can not be changed
What is a substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
What is the substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
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.
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.
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.
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 are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
Why a substance that speeds up a chemical reaction without being permanently changed itself?
A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
The substances that are produced in a chemical change are called?
chemical reaction is when a substance is changed chemicaly but not physicaly
What is the term for the substance changed during a chemical reaction?
You think probable to the reactants.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
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.
. How do substances change after a chemical reaction?
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.
