8moles of SO_2 need 11mol O_2
Moles of sO_2
So
Moles of O_2
We know
- 1mol at STP=22.4L
- 1.4mol=0.14(22.4)=3.13L O_2
The quantum mechanical model is used to describe the energy and most likely location of an electron.
Answer: Option A
<u>Explanation:
</u>
The quantum mechanical model leads to the introduction of quantum numbers representing the energy levels, sub-shells, orbitals as well as spin states of the electrons. So according to the quantum numbers we can perfectly define the position and energy of any electron in an element.
According to Pauli’s principle, any two electron cannot be having same set of quantum numbers. So, using the principle quantum number, azimuthal quantum number, magnetic and spin quantum number, we can define the energy and location of an electron in the atom.
Answer:
0.05
Explanation:
We find the rate of the chess
Sarah is 2.5/10
Arun is 1.6/8
We will get
0.25 for Sarah
0.20 for Arun
We subtract the two
0.25 - 0.20, we then get 0.05
Sarah has 0.05 more cheese in one serving than Arun
Boiling liquids that want to escape gas
