Answer:
The uncertainty of the position of the bacterium =
Explanation:
Given that:
mass (m) =0.500 fg
To kilogram; we have:
Velocity (v) = 7.00 μm/s
To meter/seconds (m/s);
Velocity (v) =
Uncertainty of the velocity is given as 4% = 0.04
Then; multiplying the velocity of the bacterium; we have:
To determine the uncertainty in the momentum;we multiply the uncertainty in the velocity by the mass:
Now; according to Heisenberg's Uncertainty Principle;
where;
= uncertainty in the position
uncertainty in the velocity
h = Planck's Constant
Thus, the uncertainty of the position of the bacterium =
Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.
Answer:
The molar mass of the unknown compound is 202.40 g/mol.
Explanation:
Let the molar mass of compound be M.
The depression in freezing point is given by:
where,
= change in boiling point = 0.81 K
=Boiling point of the solution = 3.77°C
T = freezing point of the pure solvent here benzene =5.48°C
= freezing point constant = 5.12°C/m
m = molality =
M = 202.40 g/mol
The molar mass of the unknown compound is 202.40 g/mol.
