Answer:
Pb(CH3COO)2(s) -------> Pb^2+(aq) + 2CH3COO^- (aq)
Explanation:
Recall that a strong electrolyte is an electrolyte that dissociates completely in solution. Hence, if we say that lead(II) acetate is a strong electrolyte we are actually saying that lead(II) acetate ,dissociates completely in solution to yield lead II ions and acetate ions.
This implies that the reaction equation shown in the answer section tends to go to completion since lead(II) acetate is a strong electrolyte.
The piece of evidence would suggest an unknown substance is an ionic compound is that it conducts electricity when dissolved in water.
Answer:
<h2>1.23 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>1.23 moles</h3>
Hope this helps you
