LiOH and NaOH can each react with CO2
to form the metal carbonate and H2O.
These reactions can be used to remove CO2
from the air in a spacecraft.
a. Write a balanced equation for each
reaction.
b. Calculate the grams of NaOH and of
LiOH that remove 288 g CO2 from the air.
c. NaOH is less expensive per mole than
LiOH. Based on your calculations,
explain why LiOH is used during shuttle
missions rather than NaOH.

  1. 2NaOH + CO2 ==> Na2CO3 + H2O

    Convert 288 g CO2 to moles. moles = grams/molar mass.

    Using the coefficients in the balanced equation, convert moles CO2 to moles NaOH.

    Convert moles NaOH to grams. g = moles x molar mass.

    You should be able to do the rest on your own. Post your work if you get stuck.

    I need to predict the acid/base reactions of sodium carbonate with HCl, CH3COOH, NH3, and NaOH. I'm stuck, when I'm writing out the ions to find the strongest acid and base, does the NaHCO3 become Na and HCO3, or N, H, and CO3?

  7. DrBOB222... the moles

    This is what i did thus far I wrote the eqn and i sed 1 mole of LiOH = 24g x mole = 1 g cross multiply the # of moles = 0.042mol The ratio between LiOH and CO2 is 2 : 1 i'm lost there 0.042 mols LiOH is correct. You have the ratio
