Answer: 3.613x10^24
Explanation: Avogadro’s number represents the number of atoms in one mole of substance: 6.022x10^23 atoms/mole. Multiplying the number of moles by this number reveals that, in this sample, 3.613x10^24 atoms of methane are present.
Answer:
The definition of conceptual is something having to do with the mind, or with mental concepts or philosophical or imaginary ideas. An example of conceptual is when you formulate an abstract philosophy to explain the world which cannot be proven or seen. "Conceptual."
Explanation:
Answer:
Burning, cooking, rusting, and rotting
Answer:
v = 7.85 × 10¹⁴ Hz
Explanation:
The first three energy level can be represented as follows:
⇅ ------> n₄ = 4
⇅ ------> n₃ = 3
⇅ ------> n₂ = 0
ΔE = hv =
ΔE = hv =
ΔE = hv =
ΔE = hv =
where h = planck constant = J.s
mass (m) =
e = 0.904 nm =
hv =
hv =
hv =
hv = J
v =
v =
v =
v = 7.85 × 10¹⁴ Hz (since s⁻¹ is equivalent to 1 Hz)
Thus, the frequency of an electronic transition from the highest-occupied orbital to the lowest-unoccupied orbital = 7.85 × 10¹⁴ Hz
