Answer: A
Explanation: A switch is in an improper position when the switch pole screw lies against the switch box and the runner is shorted, which causes the fuse to blow when you turn the lights off.
Answer:
Option A.
Explanation:
Probability is expressed in percent, fraction or in whole numbers
The given chemical equation represents the combustion reaction of propanoic acid:
On balancing we get,
The above balanced chemical equation tells us that, 2 mol require 7 mol for complete combustion to produce and
Given moles of = 1 mol
Calculating moles of required for combustion:
Therefore, 3.5 mol Oxygen is required for complete combustion of 1 mol propanoic acid.
Answer:
The pressure of N₂O₄ in the reaction vessel after the reaction is 290 mmHg
Explanation:
Nitrogen gas reacts with oxygen gas to form dinitrogen tetroxide.
N₂ (g) + 2O₂ (g) → N₂O₄ (g)
Therefore since by Avogadro's law equal volumes of all gases contain equal numbers of molecules, there fore as the gases are within the same vessel, thier partial pressure is equivalent to their concentration
from the reaction, 1 mole of N₂ react with 2 moles of O₂ to produce 1 mole of N₂O₄
Thus
1 mmHg of N₂ react with 2 mmHg of O₂ to produce 1 mmHg of N₂O₄
337 mmHg N₂ ×(1 mmHg of N₂O₄/ 1 mmHg of N₂) = 337 mmHg N₂O₄
580 mmHg O₂ ×(1 mmHg of N₂O₄/ 2 mmHg of O₂) = 290 mmHg N₂O₄
As seen from the above calculation, the limting reactant is oxygen and the partial pressure of N₂O₄ = 290 mmHg
