Explanation:
The quantity of moles of ethanol in the solution is:
The mass and volume of ethanol in the solution are, respectively:
The difference between the total volume of water and ethanol mixed to prepare the solution and the actual volume of solution is:
There is one atom of sulfur :)
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
Or
The explosive material in C-4 is cyclotrimethylene-trinitramine (C3H6N6O6), commonly called RDX (which stands for "royal demolition explosive" or "research development explosive").
Answer:
ΔG = -8.812 kJ/mol
Explanation:
To obtain the free energy of a reaction you can use the expression:
ΔG = ΔG° + RT ln Q
<em>Where: </em>
<em>ΔG° is Standard Gibbs Free energy: -16.7kJ/mol = -16700J/mol</em>
<em>R is gas constant: 8.314472 J/molK</em>
<em>T is absolute temperature (37°C + 273.15 = 310.15K)</em>
<em>And Q is reaction quotient: 21.3</em>
<em />
Replacing in the formula:
ΔG = ΔG° + RT ln Q
ΔG = -16700J/mol + 8.314472J/molK*310.15K ln 21.3
ΔG = -8812.4J/mol
<h3>ΔG = -8.812 kJ/mol</h3>
