Why does addition of H2SO4 stop reactions?
H2SO4 is an acid, so when you add that to the catalase reactions, the pH drops below where the catalase can function. Acids have lower pH and therefore the catalase can no longer function, so the reaction stops.
Why does heat and acid cause a catalase to stop functioning?
Catalase is a protein and proteins can de-nature or change shapes when exposed to heat. Acid is very corrosive and so my guess would be that acid would just eat away at the protein and cause the protein to lose major parts needed to function
Why does the reaction stop between magnesium and hydrochloric acid?
It could stop because there wasn't enough magnesium or hydrochloric acid for the reaction to go to completion.
What salt is created when you mix sulfuric acid potassium hydroxide?
H2SO4 + 2NaOH --> HOH + 2Na+ + SO4--Sulfuric acid and lye react to produce water and sodium and sulfate ions plus heat.Added:It will very vigorously and exothermically react with sulfuric acid. Never try this!!Be very very very careful, it even is very very dangerous to try to stop this with water: it immediately boils off (explosively), and at contact your skin is irreparably burnt to black within seconds.
What is the role of sulphuric acid in the reaction?
It's a acid, so it lowers the pH and enzymes only work at a specific pH, so it will stop and slow the reaction down.

What would the reaction rate do if another substance that binds to the active site of catalase was added?
the reaction will stop because the introduced substance that binds to the reaction site will change the shape of the reaction site so that the original substrate will no longer fit
Why is trichloroacetic acid used in protease assay?
To Stop The Reaction
Why does the reaction stop in baking soda and vinegar?
The reaction will stop when one or other of the reagents are used up. The acetic acid concentration of vinegar varies at around 5 to 10%. When used up in the reaction, then the reaction will stop.
How does the time require for the bubbles to stop reflect the amount of catalase activity in the solutions?
The longer it takes for the bubbles to stop forming, the more catalase there is present, assuming that there is enough peroxide (H2O2) to keep the catalase going.

Why did the fizzing stop when he countied to add the acid?
The fizzing stop when the chemical reaction is totally finished.

It's a acid, so it lowers the pH and enzymes only work at a specific pH, so it will stop and slow the reaction down.
Why does the reaction between calcium carbonate and sulphuric acid stop?
All the free ions are bonded
What is the Shorthand Chemical Acronym for sulfuric acid?
H2SO4This second line is there only to stop Wiki Answers bothering me that I cannot post answers in all capital letters.
