Try d cuz if im not mistaken if you burnt white phosphorus all the gas is going to take most the air
I think the correct answer from the choices listed above is option A. In the modern periodic table, elements are arranged according to increasing <span>atomic number. The atomic number represents the number of protons present for a specific atom.</span>
Answer:
The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .
The percentage yield obtained from the given reaction above is 74.8%
<h3>Balanced equation </h3>
P₄ + 6Cl₂ → 4PCl₃
Molar mass of P₄ = 31 × 4 = 124 g/mol
Mass of P₄ from the balanced equation = 1 × 124 = 124 g
Molar mass of PCl₃ = 31 + (35.5×3) = 137.5 g/mol
Mass of PCl₃ from the balanced equation = 4 × 137.5 = 550 g
<h3>SUMMARY</h3>
From the balanced equation above,
124 g of P₄ reacted to produce 550 g of PCl₃
<h3>How to determine the theoretical yield </h3>
From the balanced equation above,
124 g of P₄ reacted to produce 550 g of PCl₃
Therefore,
79.12 g of P₄ will react to produce = (79.12 × 550) / 124 = 350.9 g of PCl₃
<h3>How to determine the percentage yield </h3>
- Actual yield of PCl₃ = 262.6 g
- Theoretical yield of PCl₃ = 350.9 g
Percentage yield = (Actual /Theoretical) × 100
Percentage yield = (262.6 / 350.9) × 100
Percentage yield = 74.8%

Answer: Volume of the balloon at this altitude is 46.9 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
![\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
where,
= initial pressure of gas = 737 mm Hg
= final pressure of gas = 385 mm Hg
= initial volume of gas = 28.6 L
= final volume of gas = ?
= initial temperature of gas = ![26.8^oC=273+26.8=299.8K](https://tex.z-dn.net/?f=26.8%5EoC%3D273%2B26.8%3D299.8K)
= final temperature of gas = ![-16.3^oC=273-16.3=256.7K](https://tex.z-dn.net/?f=-16.3%5EoC%3D273-16.3%3D256.7K)
Now put all the given values in the above equation, we get:
![\frac{737\times 28.6}{299.8}=\frac{385\times V_2}{256.7}](https://tex.z-dn.net/?f=%5Cfrac%7B737%5Ctimes%2028.6%7D%7B299.8%7D%3D%5Cfrac%7B385%5Ctimes%20V_2%7D%7B256.7%7D)
![V_2=46.9L](https://tex.z-dn.net/?f=V_2%3D46.9L)
Thus the volume of the balloon at this altitude is 46.9 L
