Answer:
is the electron relaxation time
is the mean free path
Explanation:
Given:
- electron density of aluminium at room temperature,
- resistivity of aluminium,
<u>From the Drude's model we have:</u>
where:
electron relaxation time
mass of a charge
magnitude of a charge
Putting respective values for electron:
<u>Mean free path is given as:</u>
where:
mean free path
average velocity of electrons
- Now we have the the general value of average velocity of electrons at room temperature:
So,
Potential energy U= k*Q*q/r
doubling the charge Q doubles the potential energy. Since this will just be converted into kinetic energy u will double tht
The correct answer is Sulfur, Arsenic, selenium, silicon, and antimony.
The balanced chemical equation would be as follows:
<span>NaCl + AgNO3 -> NaNO3 + AgCl
We are given the amounts of the reactants. We need to determine first which one is the limiting reactant. We do as follows:
0.0440 mol/L NaCl (.025 L) = 0.0011 mol NaCl -----> consumed completely and therefore the limiting reactant
0.320 mol/L AgNO3 (0.025 L) = 0.008 mol AgNO3
0.0011 mol NaCl ( 1 mol AgCl / 1 mol NaCl) = 0.0011 AgCl precipitate produced

When radioactive decay occurs, the original nucleus splits into daughter nuclei and the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
Unstable nuclei often undergo radioactive decay. In a radioactive decay, the unstable nucleus is broken up into other nuclei. Usually, the nuclei formed during radioactive decay are smaller in mass compared to the original nucleus.
Also, the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
