Because it is extremely hot.
Answer:
b. - 184 J/K
Explanation:
- ΔSsurr = - ΔH/T....at constant P and T.
∴ ΔHrxn = 54.2 KJ = 54200 J
∴ T = 25°C ≅ 298.15 K
⇒ ΔSsurr = - (54200 J)/(298 K)
⇒ ΔSsurr = - 182 J/K ≅ - 184 J/K
Answer:
From the equation you will see that 1 mol of propane generates 4 mols of water.
Since the molar mass of water
M
(
H2O)=2×1+16=18g/mol
2 mol propane will generate
2
×4×18=144g of water
