Answer:
Lithium only has one pair of unpaired electrons.
Explanation:
We need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.
<h3>
What is Lewis dot structure?</h3>
Lewis dot structure is defined as the visual representation of atoms' electrons using a diagram. It describe the bonds that exist between a molecule's lone pairs of electrons and its atoms.
A lone pair of electrons on the atom with the formal charge of 1- can typically be converted into a bonding pair that is shared with the atom that has the formal charge of 1+ in order to reduce the formal charges when they are present.
Thus, we need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.

I believe the statement is true. The heat transfer involved here is called conduction. It is one type of heat transfer where it caused by the collisions of the particles in a certain body. As the you add heat to the object, the kinetic energy of the molecules increases therefore more collisions could happen which would mean energy is dissipated or transferred from molecule to molecule.<span />
1) Molar mass C8H9NO2
Element Atomic mass # of atoms mass
g/mol g
C 12 8 12*8 = 96
H 1 9 1*9 = 9
N 14 1 14*1 = 14
O 16 2 16*2 = 32
molar mass = 96 + 9 + 14 + 32 = 151 g/mol
2) Number of mols in a tablet
# of moles = mass / molar mass = 0.500 g / 151 g/mol = 0.003311 moles
3) 3 doses * 2 tablets * 0.003311 moles / tablet = 0.020 moles
<span>88(60) 24(365) that should be the answer after you figure it out.</span>
