Answer:
40 C atoms
Explanation:
Step 1: Write organic compound
10C₄H₁₀
We see here that in 1 mol of C₄H₁₀, we would have 4 atoms of C.
We are given that we have 10 moles of C₄H₁₀.
Therefore, we have 4 · 10 = 40 atoms C
do you have anymore numbers to add to this problem??
With an Ag concentration of 0.020 M and a Pb2+ concentration of 0.0010 M, Only PbSO₄(s) will precipitate. The correct option is C.
<h3>What is molarity?</h3>
Molarity is the measure of the concentration of any solute in per unit volume of the solution.
The equations are
![\rm Ag_2SO_4--- > 2Ag++SO4^{-2}](https://tex.z-dn.net/?f=%5Crm%20Ag_2SO_4---%20%3E%202Ag%2B%2BSO4%5E%7B-2%7D)
![PbSO_4--- > Pb_2+ +SO4^{-2}](https://tex.z-dn.net/?f=PbSO_4---%20%3E%20Pb_2%2B%20%2BSO4%5E%7B-2%7D)
Therefore:
![Ag_2SO_4=[0.02^2[0.001]]\\Ag_2SO_4=4 \times 10^{-7}](https://tex.z-dn.net/?f=Ag_2SO_4%3D%5B0.02%5E2%5B0.001%5D%5D%5C%5CAg_2SO_4%3D4%20%5Ctimes%2010%5E%7B-7%7D)
and
![PbSO_4=[0.001^2[0.001]]\\PbSO_4=4*10^{-6}](https://tex.z-dn.net/?f=PbSO_4%3D%5B0.001%5E2%5B0.001%5D%5D%5C%5CPbSO_4%3D4%2A10%5E%7B-6%7D)
Since,
, only PbSO₄ will precipitate.
Thus, the correct option is (C) Only PbSO₄(s) will precipitate.
