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

Answer:
NO is the limiting reagent.
In this reaction 0.886 mole of NO2 is produced
Explanation:
The chemical equation for this reaction is
2NO(g) + O2(g) → 2NO2(g)
In this limiting reagent reaction, 2 moles of NO reacts with one mole of O2 to produce 2 mole of 2NO2
0.886 mole of NO * (2 mole of NO2/2 mole of NO) = 0.886 mole of NO2
0.503 mole of O2 * (1 mole of NO2/1 mole of O2) = 1.01 mole of NO2
Hence, NO is the limiting reagent.
In this reaction 0.886 mole of NO2 is produced
