Answer:
A pH environment has a significant effect on an enzymes. It can affect the intramolecular forces and change the enzyme's shape -- potentially to the point where it is rendered ineffective. With these effects in mind, typical enzymes have a pH range in which they perform optimally.

Answer : The energy for vacancy formation in silver is,
Explanation :
Formula used :
or,
So,
where,
= equilibrium number of vacancies =
E = energy = ?
M = atomic weight = 107.9 g/mole
= Avogadro's number =
= density =
T = temperature =
K = Boltzmann constant =
Now put all the given values in the above formula, we get:
Therefore, the energy for vacancy formation in silver is,
Answer:
-205.7kj
Explanation:
Now adding reaction 2 and twice of reaction 3 and reverse of reaction 1, we get the enthalpy of the reaction.
The expression for enthalpy for the following reaction will be,
where,
n = number of moles
Now put all the given values in the above expression, we get:
Therefore, the enthalpy of the following reaction is, -205.7kj
Answer:
youre right i think its 1 and 5
because it cant be 2 or 3
Explanation:
I hope this answers your question(s). Have a good weekend!
The formal charge on each atom can be known by counting up the number of valence electrons that is present on each atom.
<h3>What is Lewis structure?</h3>
The term Lewis structure is the representation of a compound using its symbols and showing the valence electrons as dots. This question is incomplete as the Lewis structures were not shown.
If it is shown, we can know the formal charge on each atom by counting up the number of valence electrons that is present on each atom.
