What is the name for the chemical that takes place in a reaction?
reactant
What is the definition of excess reactant?
An excess reactant is a reactant in a chemical reaction that is present in a quantity greater than required for the reaction to take place. It is not completely consumed during the reaction, leaving some of it leftover.
What is one of of the original substances before a chemical reaction takes place?
a reactant
True or False chemical reaction occurs at the same rate no matter what size of the reactant particles?
False. The rate of a chemical reaction can be influenced by the size of the reactant particles. Smaller particles have a larger surface area, allowing for more frequent collisions between particles and therefore potentially increasing the rate of reaction.
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.
What must be broken in reactants in order for a chemical reaction to take place?
The chemical bonds among the reactant atoms or molecules must be broken down.
What is a reactant that binds to a catalyst?
A reactant that binds to a catalyst is known as a substrate. Substrates bind to the active site of the catalyst, where the chemical reaction takes place. This binding lowers the activation energy required for the reaction to occur.
What is the meaning of a chemical equation?
A chemical equation is defined as the short-hand representation of a true chemical reaction with the help of symbols and formula.We must finish our chemical reaction with as many atoms of each element as when we started.The chemical reaction takes place on the reactant side forming the 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.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
In a chemical reaction a reactant binds to an enzyme at a region known as the?
active site. This is where the reaction takes place and the substrate interacts with the enzyme to form the product. The active site has a specific shape that fits the substrate, allowing for the reaction to occur.
Why a catalyst is not considered a reactant or product in chemical reaction?
A catalyst is unchanged by the reaction, and remains as it was. It causes the start of the reaction, but is still there AFTER the reaction. Example- the catalytic converter on an automobile exhaust contains platinum metal. This causes a chemical reaction to take place in the exhaust gasses, but the metal remains in the converter, and is not consumed.
