If theres a mixture of components we can calculate the mole fraction
mole fraction can be calculated as follows
mole fraction of component =

number of moles of ethanol - 3.00 mol
total number of moles in mixture - 3.00 + 5.00 = 8.00 mol
mole fraction of ethanol =

mole fraction of ethanol is 0.375
Gymnosperms are the group of plants that produce fruit..
I think A is false
But still i am not soon sure.
Answer:
A. The molecular orbital theory of bonding is based on the mixing of atomic orbitals of similar shapes and energies to form molecular orbitals that extend to two or more atoms
Explanation:
When two atoms come close to each other, the waves of their atomic orbitals can interfere constructively or destructively, to form two new molecular orbitals that encompass the whole molecule.
B is wrong. It refers to Lewis structures.
C is wrong. It refers to VSEPR theory.
D is wrong. It refers to ionic bonding.
E. is wrong. It refers to valence bond theory.
