Answer:
How to determine the mole of LiOH required to react with 20 moles of CO₂ per day
CO₂ + 2LiOH —> Li₂CO₃ + H₂O
From the balanced equation above,
1 mole of CO₂ required 2 moles of LiOH.
Therefore,
20 moles of CO₂ will require = 20 × 2 = 40 moles of LiOH
How to determine the mole of LiOH required by two astronauts for 3 days
Mole of LiOH for 1 person per day = 40 moles
Mole of LiOH for 2 persons per day = 2 × 40 = 80 moles
Mole of LiOH for 2 persons for 3 days = 80 × 3 = 240 moles

Explanation:
Dipole moment is defined as the measurement of the separation of two opposite electrical charges.
is a bent shaped molecule with a dipole moment of 1.87.
is also a bent shaped molecule with a dipole moment of 1.10.
is a also a bent shaped molecule and has a negligible dipole moment.
has a dipole moment of 0.29.
Therefore, given molecules are arranged according to their increasing dipole moment as follows.
< < <
