The wavelength of the violet light emitted from a hydrogen atom is 410.1 nm. This light is a result of electronic transitions be
VashaNatasha [74]

Answer:

e. 4.847 x 10-19 J

Explanation:

From the given information:

The equation connecting the photon energy and the wavelength is:

E_{photon } = \dfrac {hc}{\lambda}

where;

planck's  \ constant  \ (h)= 6.626 * 10 ^{-34} J.s

velocity  \ of \  light \  (c) = 3.00 * 10^8 m/s

wavelength \lambda = 410.1 \ nm \times \dfrac{10^{-9} \ m}{1 \ nm}

\lambda = 4.101 \times 10^{-7} \ m

To determine the photon energy of violet light

E_{photon } = \dfrac {(6.626 \times 10^{-34} J/s ) \times (3.00 \times 10^8 \ m/s) }{4.101 \times 10^{-7} \ m}

= 4.847 × 10⁻¹⁹ J

Are phase changes physical or chemical changes? why?
Studentka2010 [4]
Physical! Because they do not modify the nature of the substance ( if you look at the chemical level) and it is reversible

Vapor is H20
Water is H20
Ice is H20

A chemical changes is not reversible
Burning wood for example! And the reactants interact together to form a new product.

which contains the most amount of energy a glass of water at 20C or a glass of water at 80C. EXPLAIN ANSWER
Step2247 [10]

Answer:

80C

Explanation:

As a substance gets hotter, or as a substance gets closer to the state of gas, the particles in the substance move faster, become more spread out and have more energy. This is why Gas has the most energy while solids have the least. Therefore, the hotter a substance is the more energy it has.
