Answer:
for the reaction is -3.059 kJ/mol.
Explanation:
Reaction equilibrium:
Reaction quotient (Q) for this reaction at and is:
=
= 0.0329
We know, , where is standard free energy change, R is gas constant and T is temperature in kelvin scale.
Here, = 5.40 kJ/mol
So,
= -3059 J/mol
= -3.059 kJ/mol
For this question, lets apply Avagadro's law
when Pressure and temperature are constant, the volume occupied is directly proportional to the number of moles of gases.
where V-volume, n-number of moles and k - constant
Therefore at 2 instances
where V1 and n1 are for 1st instance
and V2 and n2 are for 2nd instance
therefore
V1 = 2.4 L
n1 = 3.7 mol
n2 = 3.7 + 1.6 = 5.3 mol
since more He moles are added at the 2nd instance its the sum of the moles.
V2 needs to be calculated
V2 = 2.4 x 5.3 / 3.7
= 3.4 L
Answer is 1st option 3.4 L

another term for heat releasing-exothermic
the release of water vapor from the bodies of animals- respiration
-release of water vapor from leaves of plants - transpiration
Answer:
1) Filter to remove insoluble substances from the water
2) Use carbon to remove odor.
3) Chlorine is used to kill bacteria.
