It expands in the cracks (which I think is erosion) and it breaks the pavement because of the constant expansion and moving of pavement pushes it to break.
Hey there!
1 mol has 6.022 x 10²³ molecules.
If we have 4.2 mol F₂, multiply the number of molecules in 1 mol by 4.2.
4.2 x 6.022 x 10²³
2 sig figs
25 x 10²³
Put this properly into scientific notation.
2.5 x 10²⁴ molecules of F₂
Hope this helps!
Answer:The n = 3 shell, for example, contains three subshells: the 3s, 3p, and 3d orbitals. There is only one orbital in the n = 1 shell because there is only one way in which a sphere can be oriented in space.

Answer:
The unknown temperature is 304.7K
Explanation:
V1 = 100mL = 100*10^-3L
P1 = 99.10kPa = 99.10*10³Pa
V2 = 74.2mL = 74.2*10^-3L
P2 = 133.7kPa = 133.7*10³Pa
T2 = 305K
T1 = ?
From combined gas equation,
(P1 * V1) / T1 = (P2 * V2) / T2
Solving for T1,
T1 = (P1 * V1 * T2) / (P2 * V2)
T1 = (99.10*10³ * 100*10^-3 * 305) / (133.7*10³ * 74.2*10^-3)
T1 = 3022550 / 9920.54
T1 = 304.67K
T1 = 304.7K
