The acid is Nitric acid and the base is Zinc hydroxide.
Answer:I would copy and past but that’s a lot of work just read it
Explanation:
0.040 mol / dm³. (2 sig. fig.)
<h3>Explanation</h3>
in this question acts as a weak base. As seen in the equation in the question, produces rather than when it dissolves in water. The concentration of will likely be more useful than that of for the calculations here.
Finding the value of from pH:
Assume that ,
.
.
Solve for :
Note that water isn't part of this expression.
The value of Kb is quite small. The change in is nearly negligible once it dissolves. In other words,
.
Also, for each mole of produced, one mole of was also produced. The solution started with a small amount of either species. As a result,
.

Mass of Cl₂ : 164.01 g
<h3>Further explanation</h3>
A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol Cl₂ :
mass Cl₂(MW=71 g/mol) :
