Considering; graphite; standard enthalpy = 0 and entropy = 5.740; diamond standard enthalpy = 1.897 and entropy = 2.38.
Using the equation Delta G = Delta H - Temperature (DeltaS)
Delta H = enthalpy sum of products - enthalpy sum of reactants
Which will be; 0 -1.897 = -1.897 kJ/Mol
Delta S is the entropy sum; given by
5.740 - 2.38 = 3.36 J/Mol
We can convert Delta S from Joules to kilo Joules by dividing by 1000
we get ; 0.00336 kJ/mol
We are given a temperature in kelvin which suits the calculations ((298 k)
Therefore; using the equation;
= -1.897 - (298 × 0.00336) = -2.90 kJ
Thus; the standard gibbs free energy will be; -2.9 kJ
433.8267 g/mol according to Chemical aid
<span>The answer is Potassium-40</span>
Is is 96.3% you do ((actual yield)/(theoretical yield)) * 100
Answer is: there are 14 atoms represented by the formula (NH₄)₂CO₃.
In ammonium carbonate there are two nitrogen atoms (because two ammonium cations), eight hydrogen atoms (because two ammonium cations), one carbon atom and three oxygen atoms:
2 · 1N + 2 · 4H + 1C + 3O = 14 atoms.
Ammonium carbonate<span> is a salt.</span>
