A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.
We have that the value of Ki for the <em>inhibited </em>reaction
- The place the enzyme inhibitor binds solely to the complicated fashioned between the enzyme and the substrate.
- KI = 3.551mM
<h3>Chemical Reaction</h3>
a)
Generally, if the fee of Vmax binds, the place the enzyme inhibitor binds solely to the complicated fashioned <em>between </em>the enzyme and the substrate.
b) V diminished through 70%
Thereofore
Alternate = 1 - 0.7 = 0.3V
Hence
0.3 =1/ ( 1 + [I]/KI)
1= 0.3(1 + 0.657/KI )
0.3 + 0.1971KI = 1
KI = 3.551mM

The sun is not always shining. You have shadows cast by buildings, people, and other objects. Not to mention that throughout a large portion of time it would be night.
Answer:
Reactions of sodium with water and dilute acid
Sodium reacts explosively with dilute HCl(aq) to produce NaCl(aq) and H₂(g)
2Na (s) + 2HCl(aq) → 2NaCl(aq) + H₂(g)
Sodium reacts violently with cold water to produce NaOH(aq) and H₂(g)
2Na (s) + H₂O(l) → 2Na(OH)(aq) + H₂(g)
The produced hydrogen may become ignited and explode
Reactions of iron with water and dilute acid
Iron reacts very slowly with dilute acid to produce iron (II) chloride and hydrogen gas
Fe (s) + 2 HCl (aq) → FeCl₂ (aq) + H₂ (g)
Iron does not react with cold water. Iron reacts only with steam
Explanation:
Answer: Option (a) is the correct answer.
Explanation:
Enthalpy is defined as the total amount of heat present in a system.
When there is bond formation in a chemical reaction then it means energy is released. Hence, the reaction is exothermic in nature and 
< 0 or negative.
On the other hand, when breaking of bonds occurs then energy is absorbed by the system. Hence, the reaction is endothermic in nature and > 0 or positive.
Thus, in the given reaction 
, the state is changing from liquid to solid.
This means atoms are coming close to each other and hence, there is occurrence of bond formation. As a result, energy will be released to the surroundings.
Hence, we can conclude that H < 0 for the given reaction.
