Answer: Enzymes speed up the reaction rate.
Enzymes are regenerated when the reaction is completed.
Enzymes affect the reaction pathway by forming an enzyme-substrate complex.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Enzymes are biocatalysts and are highly specific in their action. The specificity of enzymes is due to the presence of some specific regions called as active sites. These active sites form weak bonds with substrate molecules.
The specific binding leads to formation of an enzyme substrate complex which accounts for high specificity of enzyme catalyzed reactions.
Once a proper orientation is achieved, substrate molecules react to form products and products leave the enzyme surface as they do not have any affinity towards the enzyme site and are regenerated at the end.
Enzymes work best in optimum temperature and pH range.The enzyme gets denaturated at high pH and temperature.
Answer:
Ammonia gas(an alkaline gas with characteristics of choking or irritating smell) is not liberated when 6mole of HCl is added to the solution instead of 6mole of NaOH, to test for the presence of ammonium ion in the solution
Explanation:
As expected, when testing for ammonium ion in a solution (precisely ammonium salt solution), Sodium Hydroxide (NaOH) is required as the test reagent.
When NaOH is added to the solution, A gas with characteristics of choking or irritating smell is liberated.
This gas turn red litmus paper blue.
This liberated gas is an alkaline gas, which is confirmed as an ammonia gas(NH3).
If HCl is added instead of NaOH, the ammonia gas will not be liberated, which indicates that the test reagent used is wrong.
Answer:
2BA + 0 =2BAo
2
Explanation:
BA stands for barium and O stands for Oxide
I believe the correct order of words should be:
Counterclockwise
Crescent
Full
Half
Faces?
Waxing
Right
Waning
Left
I am not sure on faces, but I don't see any other words from the bank that would fit that description. Hope these are correct and hope I helped!
<h2>It means that there are Z positive nuclear charges, and this determines the identity of the element. If the element is neutral, this means that there are precisely Z electrons, and the overall electronic charge is −Z . And thus the net ELECTRIC charge of the ATOM is Z+(−Z)=0 , i.e. zero </h2>
