Answer: It shows that light acts like a wave, but also to demonstrate that electrons can act like waves and create interference patterns.
Option B.
Current atomic models show the positive charged particles (protons) concentrated in the center (nucleus) of the atom, along with the neutrons, and the negative charged particles (electrons) distributed around (far from) the nucleus.
Answer:
at P = 101 KPa ⇒ S = 2.1 g/L
Explanation:
Henry's law:
∴ K: Henry's constant
∴ <em>C</em> is the concentration ≡ Solubiluty (S)
∴ S = (8.4 g/L)*(Kg/1000 g)*(1000 L/m³) = 8.4 Kg/m³
∴ P = (404 KPa)*(1000 Pa/KPa) = 404000 Pa
∴ Pa = Kg/ms²
⇒ S = K(404000 Pa) = 8.4 Kg/m³
⇒ K = 2.079 E-5 s²/m².......the henry's constant for this gas
at P = 101 KPa = 101000 Pa
⇒ S = (2.079 E-5 s²/m²)*(101000 Kg/ms²)
⇒ S = 2.1 Kg/m³ = 2.1 g/L
There must be two oxygen atoms to form covalent bond as when each oxygen atom contribute 4 electrons to the another, the atoms will become stable as they both have 8 electrons on the outermost shell. Refer to the dots and cross diagram i drew.
