Answer:
frequency of light = 
Explanation:
we know that relation between frequency and wavelength of light is
frequency × wavelength = speed of light.
therefore frequency = 
= 
=

<span>The scientific knowledge that
was necessary for Schrodinger’s work is the Bohr’s model. Unlike the Bohr
model, the quantum model does not define the exact path of an electron. The electron
is likely to be in a less dense area of cloud.</span>
<u>Given:</u>
Mass of Ba = 1.50 g
Mass of H2O = 100.0 g
Initial temp T1 = 22 C
Final Temp T2 = 33.1 C
specific heat c = 4.18 J/g c
<u>To determine:</u>
The reaction enthalpy
<u>Explanation:</u>
The heat released during the reaction is:
q = - mc(T2-T1) = - (100+1.5) g *4.18 J/g C * (33.1-22) C = -4709.4 J
# moles of Ba = Mass of Ba/Atomic mass of Ba = 1.5 g/137 g.mol-1 = 0.0109 moles
ΔH = q/mole = - 4709.4 J/0.0109 moles = - 432 kJ/mol
Ans : The enthalpy change for the reaction is -432 kJ/mol
Polymerization is the chemical reaction between monomer molecules. The result of the reaction are polymer chains or three-dimensional networks. A polymer is build from several blocks - monomers. Polymerization is most directly responsible in determining the primary structure of a protein.
