Answer:
True.
Explanation:
The Hund's Rule states that all orbitals must be singled occupied before any orbital is doubly occupied, and all the electrons at the singly occupied orbitals have the same spin number. By doing that, the electrons filled the lowest energy orbitals first.
The 2p level has 3 orbitals: 2px, 2py, and 2pz. So, when filling it, first put an electron in the 2px, then in the 2py, then and the 2pz (all with the same spin). After that, the remains electrons can be paired up.
Answer:
Hi there!
The correct answer is 2.29 x 
molecules
Explanation:
To convert from the moles to molecules:
1 mole = 6.022 x 10²³ molecules
so basically you multiply 3.8 by 6.022 x 10²³
and you get: 2.29 x
I try but I don’t find the answer sorry
If this is the transfer of heat by direst contact its radiation, but if the material for example, fire, that heated a large air mass, for example, a house, the fire would heat up the air being convection, but if the martial for example, fire, heats your had when your hand is close to the fire, its radiation.
