Answer:
1.02 grams
Explanation:
The reaction between Na₃PO₄ and BaCl₂ is:
2Na₃PO₄(aq) + 3BaCl₂(aq) → Ba₃(PO₄)₂(s) + 6NaCl(aq)
We need to find the number of moles of Na₃PO₄ and BaCl₂:
Now, we need to find the limiting reactant:
We have that it is needed 0.0033 moles of Na₃PO₄ to react with BaCl₂ and we have 0.01 moles of Na₃PO₄, so the limiting reactant is BaCl₂.
The number of moles of Ba₃(PO₄)₂ is:
Finally, the mass of Ba₃(PO₄)₂ is:
Therefore, should be obtained 1.02 grams of the precipitate.
I hope it helps you!
Explanation:
Phylogeny is the branch of science that deals with phylogenesis. Phylogenesis is the development of a particular feature of an organism
Answer:
Explanation:
Data:
p₁ = 1 bar; V₁ = 5 L; T₁ = 0 °C
p₂ = 1 bar; V₂ = ?; T₂ = 45 °C
The pressure and the number of moles are constant, so, to calculate the volume, we can use Charles' Law.
Calculations:
(a) Convert temperatures to kelvins
T₁ = (0 + 273.15) K = 273.15 K
T₂ = (45 + 273.15) K = 318.15 K
(b) Calculate the new volume
