Answer:
A Maxwell-Boltzmann Distribution is a probability distribution used for describing the speeds of various particles within a stationary container at a specific temperature. The distribution is often represented with a graph, with the y-axis defined as the number of molecules and the x-axis defined as the speed.
Explanation:
The ionic strength of a solution, I, is defined as
I=1/2 Σ m_i z_i^2
Where m_i is the concentration of the ion, and z_i is the charge of the ion.
For 1 M NaCl solution, Ionic strength I = ½ (1*12 + 1*12) = 1.00;
For, 1 M (NH4)2SO4, concentration of [NH4] = 2 M and [SO4] = 1 M;
I = ½ (2*12 + 1*22) = 3.00;
so ionic strength of 1 M (NH4)2SO4 is different, therefore it is a serious error.
Hey there !
We know that
Atomic number , z = number of n+number of e
=> Z = 38+28 = 66
Hence the answer is B)Nickel-66
I hope this helps you:)
Have a good day ;)
Answer:
if you are working with a substances that produce or generate toxic or harmful fumes, vapours, gases, dust or chemical aerosols
it should be carried out in a fume cupboard to eliminate or reduce the risk of exposure to an acceptable and safe level.
Heat up the solvent. This will cause the molecules of the solvent to become more energized and "expand" to allow for more solvent to be added. However, once the solvent cools down, the extra solute may fall out as a precipitate.
This is how rock candy is made, by the way.
