Answer:
The answer is
<h3>
</h3>
Explanation:
The Ka of an acid when given the pH and concentration can be found by
<h3>
</h3>
where
c is the concentration of the acid
From the question
pH = 5.82
c = 0.010 M
Substitute the values into the above formula and solve for Ka
We have
<h3>
</h3><h3 /><h3>
</h3><h3 /><h3>
</h3>
Multiply through by - 2
<h3>
</h3>
Find antilog of both sides
We have the final answer as
<h3>
</h3>
Hope this helps you

Answer: The energy of a mole of photon associated with this frequency is 
Explanation:
The energy and frequency are related by :
E = energy of photon
N = number of moles = 1
h = planks constant = 
= frequency = 
The energy of a mole of photon associated with this frequency is
Answer:the energy required by an atom to lose or gain electron (e-) to be able to form ions.either cation or anion.
Explanation:
to lose or gain e- an atom has to donate or receive e- to to this it requires the more easily it can lose an electron the more electro positive it is and the more easily it gains electron the more electro negative it is.
Answer:
1.73 M
Explanation:
Molarity is moles per liter, so we need to divide 7.47 moles by 4.31 liters to get the molarity of the solution.
7.47/4.31 ≈ 1.73 M
