An atom (not a hydrogen atom) absorbs a photon whose associated wavelength is 300 nm and then immediately emits photon whose ass
KIM [24]

Answer:

The net energy is 2.196 eV

Explanation:

Basically, the energy of an atom increases when it absorbs a photon. In addition, the wavelength of the emitted photon is longer such that the atom absorbed a net energy in the process.

Using:

ΔE = h*c*(1/λ_{1} - 1/λ_{2})

where:

ΔE is the net energy in eV (electron-volt). 1 eV is equivalent to 1.602*10^{-19} J.

h = 4.135*10^{-15} eVs

c = 3*10^{8} m/s

λ_{1} = 300 nm = 300*10^{-9} m

λ_{2} = 640 nm = 640*10^{-9} m

Thus:

ΔE = 4.135*10^{-15} eVs*3*10^{8} m/s*(\frac{1}{300*10^{-9}m } }-\frac{1}{640*10^{-9}m })

ΔE = 4.135*10^{-15}*3*10^{8}*1.77*10^{6} eV = 2.196 eV

What kinds of scientific investagations involve making observations
bulgar [2K]

Scientific investigations that involve some kind of testing will make use of observations.  Generally speaking, making observations is the first step of the scientific method.  Based on those observations, a question is asked, and then a hypothesis and prediction will be stated.  A scientist will set up a test, observe the outcome, and collect data on the test.  That will lead the scientist to some kind of conclusion relating to the initial question and hypothesis....

Bond formation is the way in which atoms interact to form compounds.

<h3>What is bond formation?</h3>

Bond formation is the way in which atoms interact to form compounds. The following are the kind of bonds formed by the atoms;

C and AI - ionic bond

N and P - covalent bond

N and O - covalent bond

The bonds in each of the lattices are;

CuO - ionic bond

Hg - metallic bond

P2O5 - covalent bond

P - covalent bond

CaCl2 - ionic bond

The following is a depiction of the processes shown;

Na0 →Na+1 - oxidation

P0→P+5  - oxidation

AI+3 → AI0 - reduction

The balanced reaction equations are;

2H2O + F2 → 2HF + O2

SO2 + 3H2 → H2S + 2H2O

2H2SO4 + C → 2SO2+CO2+2H2O
