Which of these species would you expect to have the lowest standard entropy (S°)? a. CH4(g)
b. H2O(g)
c. NH3(g)
d. HF(g)

d. HF(g)

Explanation:

Hello,

In this case, the standard entropy S° could be predicted by looking at the amount of bonds the compound has, thus, the fewer the number bonds, the lower the standard entropy, it means that d. HF(g) has lowest value as it has one bond only whereas methane has four bonds, water two bonds and ammonia three bonds.

Best regards.

lol idk man i guess u gotta ask bill nye the science guy
