The sign of the entropy change, ΔS, for the following processes include:
- I2 (s) + ½ Cl2 (g) ← → ICl (g) - positive
- 3 Ag (s) + 4 HNO3 (aq) → 3AgNO3 (aq) + NO (g) + 2 H2O (l) - positive
- Cl2 (g) → Cl2 (l) - negative
- C5H12 (g) + 8 O2 (g) → 5 CO2 (g) + 6 H2O (l) - negative
What is Entropy?
This is referred to the degree of randomness or disorderliness of a system and is denoted as S.
Entropy change is usually positive when solid or liquid reactant is converted into gas product and vice versa.

The substance should be in liquid state.
First, it takes up space in the container, which leads to that it shouldn't be a solid, because solid doesn't change its shape easily.
Second, it has a fixed volume, it's difficult to compress the substance, therefore it shouldn't be gas too, as gas can be compressed easily.
Therefore we're left with liquid. And both of these given properties fits the property of liquid.
Answer:
Theoretical yield = 4.09 g water.
75% yield = 3.07g water.
Explanation:
C3H8 + 5O2 ---> 3CO2 + 4H2O
Using atomic masses:
(12 *3 + 8 * 1.008) g C3H8 yield (theoretically) (4* (2*1.008 + 16) g water
44.06g C3H8 yields 72.06g water
So 2.5 g yields (72.06/44.06) * 2.5
= 4.09 g water.
If the yield is 75% then it is 4.09 * 0.75
= 3.07 g water.
