Answer:
The process of dissolving increases entropy because the solute particles become separated from one another when a solution is formed.
The balanced equation for the above reaction is;
CH₄ + 2O₂ ---> CO₂ + 2H₂O
Stoichiometry of CH₄ to O₂ is 1:2
The number of methane moles present - 1.44 g/ 16 g/mol = 0.090 mol
Number of oxygen moles present - 9.5 g/ 32 g/mol = 0.30 mol
If methane is the limiting reagent,
0.090 moles of methane react with 0.090x 2 = 0.180 mol
only 0.180 mol of O₂ is required but 0.30 mol of O₂ has been provided therefore O₂ is in excess and CH₄ is the limiting reactant.
Number of moles of water that can be produced - 0.180 mol
Therefore mass of water produced - 0.180 x 18 g/mol = 3.24 g
Therefore mass of 3.24 g of water can be produced
Answer:
340 J·K⁻¹mol⁻¹
Explanation:
I looks like the standard entropy increases approximately linearly with the number of C atoms.
I plotted S° vs the number of C atoms and got the graph shown below.
It appears that S° for four carbon atoms should be about 340 J·K⁻¹mol⁻¹.·
