Answer:
Explanation:
Wegener figured out what Pangea looked like because he rearranged the continents, joining them so that the distribution of the fossils matched up across the continents.
44g per mole of CO2(1 mole=44g)
Expression for the Balmer series to find the wavelength of the spectral line is as follows:
1 / λ = R
Where, λ is wavelength, R is Rydberg constant, and n is integral value (4 here → Fourth level)
Substitute 1.097 x 10⁷ m⁻¹ for R and 4 for n in the above equation
1 / λ = (1.097 x 10⁷ m⁻¹)
= 0.20568 x 10⁷ m⁻¹
λ = 4.86 x 10⁻⁷ m
since 1 m = 10⁹ nm
λ = 486 nm
