When the number of moles = mass/molar mass
so the number of moles of CO = mass of CO sample/molar mass of CO
when the mass of CO sample = 36.55 g
and the molar mass of CO = 12 + 16 = 28 g/mol
by substitution:
∴moles of carbon monoxide = 36.55 g / 28 g/mol
= 1.3 moles
The epicardium (external layer), the myocardium (middle layer) and the endocardium (inner layer).
Answer:
Transition from n = 4 to n = 1 corresponds to shortest wavelength.
Explanation:
Process
A 0.9375
B 0.75
C 0.0421
D 0.1875
According to Rydberg equation for electronic transition in H-like atoms:
where, is wavelength of light emitted or absorbed, is Rydberg constant.
So, higher the value of , lower will the corresponding wavelength of light.
Hence process A will be associated with shortest wavelength.
Answer:
Equilibrium concentration of is
Explanation:
Construct an ICE table to calculate changes in concentration at equilibrium.
I: 0.1 0 0
C: -x +x +x
E: 0.1-x x x
=
(species inside third bracket represent equilibrium concentrations)
or,
So, M
or,
So, equilibrium concentration of ==x=
Answer:
a) a space in an atom where an electron is most likely to be found
Explanation:
Atomic orbital is the mathematical function which describes wave-like behavior of the electrons present in the atom.
It is used to calculate probability of finding the electron of the atom in any region around nucleus of the atom. Atomic orbital is the physical region or a three dimensional space where the probability of finding the electron is more than 90% which also means that the space where an electron is most likely to be found. They are boundless space and have definite energy.
Option A best describes atomic orbital.
