Explanation:
Answer:
The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.

Answer:
1.5 m
Explanation:
Step 1: Given data
Maximum speed recorded for a giant tortoise (s): 0.11 m/s
Time elapsed (t): 6.0 h
Step 2: Convert "s" to mi/h
We will use the following conversion factors:
- 1 mi = 1609.34 m
- 1 h = 3,600 s
Step 3: Calculate the distance traveled (d) by the giant tortoise
We will use the following expression.
s = d/t
d = s × t
d = 0.25 m/h × 6.0 h
d = 1.5 m
Answer:
The change in entropy is -1.66 kJ/K.
Explanation:
Heat of vaporization of acetic acid = 41.0 kJ/mol
Heat of condensation of acetic acid = -41.0 kJ/mol
Mass of acetic acid = 954 g
Condensing temperature of acetic acid =118.1 °C = 391.25 K
Moles of acetic acid =
Heat evolved during condensation of 15.8867 moles of acetic acid:
Entropy change = ΔS =
The change in entropy is -1.66 kJ/K.
