What else can I help you with?
What is the substance present at the start of a reaction?
The substance present at the start of a chemical reaction is called a reactant. Reactants are the starting materials that undergo chemical changes to form products during a reaction.
What is an element or compound that enters into a chemical reaction?
A reactant is a substance that enters into a chemical reaction and is transformed into a new product. It is present at the start of the reaction and gets consumed during the process.
What is a substance that enters into a chemical reaction called.?
The reactant is the substance present at the start of a chemical reaction, while the product is the substance(s) formed from a chemical reaction.
What is the reactant(s) in the chemical equation below?
The reactants in a chemical equation are the substances that are present at the start of a reaction and are used up during the course of the reaction. If you provide the specific chemical equation, I can help you identify the reactant(s).
Is a reactant in a chemical reaction?
In any chemical reaction you start out with certain chemicals which are called the reactants, and they then react and turn into other chemicals which are called the products.
What do you start off with in a chemical reaction?
It is neither, the reaction is the process. The chemicals 'put in' to the reaction are called reactants, and those formed by the reaction are products
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Difference between a reactant and product?
A reactant is a substance that undergoes a chemical reaction, while a product is a substance that is formed as a result of that reaction. Reactants are consumed during the reaction, while products are the end result of the reaction.
What are the substances you start with in a chemical reaction called?
The substances you start with in a chemical reaction are called reactants. Reactants are the starting materials that undergo changes to form new substances called products.
What is a chemical reactant in a chemical reaction?
A reactant is the starting material of a reaction. For example, in the reaction 2H(+) + O(2-) --> H2O, both H(+) ions and the O(-) ion are the reactants, whereas H2O is the product of the reaction. A reactant is something that REACTS.
How does an equilibrium reaction respond to the addiof extra reactant?
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)
Do chemical reactions start with a reactant?
yes
