EDTA removes the ions that lactase needs to function as an enzyme. If enough EDTA is added, lactase will no longer have any of it's ion cofactors to aid in the break down of lactose.
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
MnO2 is added as a catalyst in the decomposition of hydrogen peroxide (H2O2) reaction to increase the rate of the reaction. It provides a surface for the reaction to occur on, which lowers the activation energy needed for the decomposition of hydrogen peroxide into water and oxygen gas.
The chemical equation for the reaction when copper is added to aluminum sulfate is: 3Cu + 2Al2(SO4)3 -> 3CuSO4 + 2Al
Reaction between an acid and a metal is usally, salt and hydrogen. So i think the reaction between chlorine and acid forms a salt and a gas.
When bromine water is added to paraffin, no visible reaction occurs. Paraffin is a non-reactive hydrocarbon compound, so it does not undergo a chemical reaction with bromine. The bromine remains as a colored solution with no change in the paraffin.
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
Milk that has lactase added.
The principle behind lactose extraction from milk is enzymatic hydrolysis. The enzyme lactase is added to milk, which breaks down lactose into its constituent sugars, glucose and galactose. The chemical reaction can be represented as: Lactose + Water → Glucose + Galactose
Foods that have added chemicals that it naturally does not contain. Examples are adding stenols to breads or lactase enzymes to milk.

When enzymes are boiled they become denatured, meaning they lose their function because they lose their shape. Any change in temperature or pH other than the one they are accustomed to will disturb an enzyme's shape; simply reverse their environment changes, and they'll go back to their correct function.
This is a neutralization reaction.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
Dilution.
"because the reaction is to slow to make an effect, if a enzyme is added then it can hydrolyse lactose but it can take more than 6 years without the addition of an enzyme" Is bull**** the real answer is because the active site of the two substances are different and so the sucrase becasue Lactose has a different shape/structure which does not fit/bind to active site of enzyme/sucrase.
If the reaction is endothermic in nature then heat should be added to it,otherwise all chemical reaction neddn't heat always.
... addition reaction; the hydrogen molecule is split, one of its atoms is added to each carbon atom that is initially double bonded, and an alkene becomes an alkane. --- ... known as hydrogenation.
