Answer: True
Explanation: Frequency by definition is the number of waves that pass a fixed point given a certain amount of time. The shorter the wavelength, the higher the frequency.
The first blank is a compound, second is a mixture
Answer:
a) cu2+ + 1Hg (l) 1Cl- equilibrium cu (s) + Hg2Cl2 (s)
b) 0.068 V.
Explanation:
A) Cu2+ + 2e- euilibrium cu (s)
Hg2Cl2 + 2e- equilibrium 2Hg (l) + 1cl-
Cell Reaction: cu2+ + 1Hg (l) 1Cl- equilibrium cu (s) + Hg2Cl2 (s)
B) To calculate the cell voltage
E = E_o Cu2+/Cu - (0.05916 V / 2) log 1/Cu2+
putting values we get
= 0.339V + (90.05916V/2)log(0.100) = 0.309V
E_cell = E Cu2+/Cu - E SCE = 0.309 V - 0.241 V = 0.068V.
This is a lab assignment, you need to do something physically to find your answers
<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Nuclear fission reaction is defined as the reaction in which 1 heavier nuclei splits into two or more smaller nuclei.
As, nuclear fission reactors require a large amount of energy to split the nucleus, hence it is bombarded with a particle in order to star the reaction.
In a nuclear reaction, a large fissile atomic nucleus like Uranium-235 
or Plutonium-239 
when absorbs a neutron, it undergoes nuclear fission reaction.
Hence, in the given options, uranium-235 is absorbing a neutron. Therefore, the correct answer is Option d.
