The reaction is 2 NO (g) <----> N2(g) + O2
partial pressures
Initial 37.30 0 0
Change -2p +p +p
Equilibrium 37.30-p p p
Kp = pN2 X pO2 / (pNO)^2
2400 = p^2 / (37.30-p)^2
3339096 - 179040p + 2400p^2 = p^2
2399p^2 + 3339096 -179040 p = 0
On solving
p = 36.55atm
Thus partial pressure of N2 and O2 = 36. 55 atm
Answer: THREE<span> different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine atom.
Explanation: When two Hydrogen atoms in ethylene (
C</span>
₂H₄) are replaced with Fluorine and Chlorine atom then the new molecular formula is
C₂H₂FCl.
Compounds having same Molecular formula but different structural formula are called as Isomers.
First Isomer of C₂H₂FCl is
1-chloro-1-fluoroethene, in which F and Cl at geminal position (attached to same Carbon atom).
Other two Isomers are
Geometrical Isomers of
1-chloro-2-fluoroethene, in which F and Cl at different carbon atom and having different position is space. The one in which both F and Cl at opposite side forms
(<em>
trans</em>
)-1-chloro-2-fluoroethene and the one in which both are in same side is called as
(<em>
cis</em>
)-1-chloro-2-fluoroethene.
In the modern periodic table the elements are arranged in order of increasing atomic number.
Answer:
20 molecules of oxygen gas remains after the reaction.
Explanation:

Molecules of ethyne = 52
Molecules of oxygen gas = 150
According to reaction, 2 molecules of ethyne reacts with 5 molecules of oxygen gas.
Then 52 molecules of ethyne will react with:
of oxygen gas.
As we can see that we have 150 molecules of oxygen gas, but 52 molecules of ethyne will react with 130 molecules of oxygen gas. So, this means that ethyne is a limiting reagent and oxygen gas is an excessive reagent.
Remaining molecules of recessive reagent = 150 - 130 = 20
20 molecules of oxygen gas remains after the reaction.
