Electronic configuration is given by
- 1s orbital is filled
- 2s orbital is unfilled
So
Answer: AgNO3 is the limiting reactant.
Explanation:
1) Balanced chemical equation:
<span>Given: 2AgNO3 + NiCl2 → 2AgCl + Ni(NO3)2
2) Mole ratios:
2 mol AgNO3 : 1 mol NiCl2 : 2 mol AgCl : 1 mol Ni(NO3)2
3) Convert 0.847 g of AgNO3 to moles
n = mass in grams / molar mass
molar mass = sum of the masses of all the atoms in the molecular formula
molar mass of AgNO3 = 107.9 g/mol + 14.0 g/mol + 3*16.0 g/mol = 169.9 g/mol
n = 0.847 g / 169.9 g/mol = 0.00499 mol AgNO3
4) Convert 0.650 g of NiCl2 to moles
n = mass in grams / molar mass
molar mass NiCl2 = 58.7 g/mol + 2*35.5 g/mol = 129.7 g/mol
n = 0.650 g / 129.7 g/mol = 0.00501 mol NiCl2
5) Compare the theoretical mole ratio with the actual ratio:
Theoretical mole ratio: 2 mol AgNO3 / 1 mol NiCl2
Actual ratio: 0.00499 mol AgNO3 / 0.00501 mol Ni Cl2 ≈ 1:1
Therefore, the amount of AgNO3 is half the required amount need to react with all the NiCl2, which means that the AgNO3 will react completely and there will be an excess of NiCl2. The reactant that is consumed completely while the other is left, is the limiting reactan. This is, AgNO3 is the limiting reactant.</span>
Answer:
Keq=0.866
Explanation:
Hello,
In this case, the undergone chemical reaction is:
In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount (
) was:
In addition, the produced amount of NO₂ is:
Finally, considering the flask's volume, the equilibrium constant is then computed as follows:
Best regards.
