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

The second one is endothermic as endothermic reactions require energy for the reaction to take place.
What do you need help with
<span> Well, here are the characteristics of ionic compounds: 1) Because of the electrostatic force of attraction (one of the strongest force), these types of compounds are usually rigid. 2) High melting points (like REALLY high compared to other colavent compounds). Ex. table salt (NaCl melts at 1714 degrees fahrenheit, while CH4 melts at -295 degrees fahrenheit). See the drastic difference? 3) Majority of ionic compounds dissolve easily in water. Notice how I say majority, as some ionic compounds are insoluble in water, and this just have to do with their intermolecular attraction between themselves relative to that between the ions and water. If for any reason you need to know these solubility characteristics, just google solubility table or something along that line. 4) When dissolved in a solution, any ionic compound can conduct electricity because the ions are floating freely and can therefore transfer electrons around. In their solid form, however, they cant because all the ions are stuck in place and cant move around. 5) Ionic compounds form a really specific shape, and all the ions are orderly placed and evenly distributed in the crystal lattice. The geometric shape of the compound is a chemical property, which means that it varies across species.</span>
What about understanding atoms and compounds?
