This means that more and more carbon dioxide will continue to accumulate in the shuttle, which causes two problems. ChemiDay you always could choose go nuts or keep calm with us or without. 2.64 moles LiOH x 1 mole H2O/ 2 moles LiOH =1.32 moles H2O. Add / Edited: 12.06.2015 / Evaluation of information: 5.0 out of 5 / number of votes: 1. Favorite Answer. First, too much carbon dioxide decreases the concentration of oxygen in the shuttle, which makes it difficult for astronauts to breathe. Why do you think NASA uses {eq}LiOH Li2CO3 + HBr ==> LiBr + H2O + CO2 You will need to balance it Li2Co3+2HBr->H2Co3+2LiBr then you seprate Li(aq)+1 + Co3(aq)+2 + 2H(aq)+1 + 2Br(aq)+1 --> H(aq)+1 + Co3 (aq)+2 + 2Li(aq)+1 + Chemistry Dr.Bobb222 please help balance the following oxidation-reduction reactions, which occur in acidic solution, using the half-reaction method. Some NASA spacecraft rely on this lithium hydroxide reaction to remove exhaled carbon dioxide from the air inside the spacecraft. Answer to: Lithium hydroxide, LiOH, reacts with carbon dioxide to produce lithium carbonate, Li2CO3. Сoding to search: 2 LiOH + CO2 = Li2CO3 + H2O. Reaction stoichiometry could be computed for a balanced equation. The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH). Substitute immutable groups in chemical compounds to avoid ambiguity. Since it takes 2 moles of LiOH to yield one mole of water, a 100% complete reaction would yield 18 grams of water for each 48 grams of LiOH, or .375 grams of water for each gram of LiOH. Enter either the number of moles or weight for one of the compounds to compute the rest. If you do not know what products are enter reagents only and click 'Balance'. If you do not know what products are enter reagents only and click 'Balance'. Answer to: Lithium hydroxide, LiOH, reacts with carbon dioxide to produce lithium carbonate, Li2CO3. A mole of LiOH is 24 grams, and a mole of water is 18 grams. 132.03 g / 44.009g/mol = 3 mol. Our experts can answer your tough homework and study questions. © copyright 2003-2020 Study.com. because LiOH: CO2= 2:1. MM for CO2 is 44.009g/mol. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. … Lithium hydroxide react with carbon dioxide. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. Lithium hydroxide, {eq}LiOH 1 decade ago.

Inside the filter, carbon dioxide is removed from the air when it reacts with lithium hydroxide to produce lithium carbonate. a) Describe why the amount of lithium hydroxide present limits the amount of time the astronauts can spend in space. Please register to post comments. The balanced equation would be 2LiOH + CO2 --> Li2CO3 + H20. The mass on a space shuttle is always minimized because the greater the mass, the greater the fuel needed to exit the atmosphere. The balanced equation tells us that 2 moles of LiOH react with one mole of CO2. Become a Patron! 6mol* 23.9479g.mol= 143.69 g. so answer is 143.69g Answer Save. 2LiOH + CO 2 → Li 2 CO 3 + H 2 O [ Check the balance ] ... 2 LiOH + CO2 = Li2CO3 + H2O. 2LiOH + CO2 -> H2O + Li2CO3. Become a Patron! Air is pumped through a filter containing lithium hydroxide. 2LiOH+CO2---> Li2CO3+ H2O. If too much carbon dioxide is present relative the molar ratios of the lithium hydroxide and carbon dioxide, lithium hydroxide will be the limiting reactant and the reaction cannot proceed. Relevance. Sciences, Culinary Arts and Personal Carbon dioxide is produced every time a person exhales. Answer Save. b) Sodium hydroxide, {eq}NaOH {/eq}, reacts with carbon dioxide to produce lithium carbonate, {eq}Li_2CO_3 Li2CO3 + HBr ==> LiBr + H2O + CO2 You will need to balance it Li2Co3+2HBr->H2Co3+2LiBr then you seprate Li(aq)+1 + Co3(aq)+2 + 2H(aq)+1 + 2Br(aq)+1 --> H(aq)+1 + Co3 (aq)+2 + 2Li(aq)+1 + Chemistry Dr.Bobb222 please help balance the following oxidation-reduction reactions, which occur in acidic solution, using the half-reaction method. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required.
