Answer:
The container that has 0.20 moles of the compound has more moles compared to the container that has 0.15 moles of compound A
Explanation:
The molarity is defined as the concentration of a substance in solution, expressed as the number of moles of a solute per liter of solution.
From the given information.
In compound A
Molarity of the solution = 0.15 molar = 0.15 m/L
It implies that, In compound A, there are 0.15 moles present in 1 L of the solution.
Similarly;
In compound B
Molarity of the solution = 0.20 molar = 0.20 m/L
It implies that, In compound B, there are 0.120 moles present in 1 L of the solution.
Thus, we can conclude that:
The container that has 0.20 moles of the compound has more moles compared to the container that has 0.15 moles of compound A
When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS
