Your answer should be an explanation! You're not solving anything. Note! Make an accurate claim: The limiting reagent in this scenario is _____. Provide additional details and use subject specific language. Cite evidence from what's given to you in the problem that supports your answer, hint: look at that equation!. Lastly! Fully connect the evidence to the claim/your answer to the question. Include subject specific language in your reasoning. The two images attached are examples of how your response SHOULD look.
The Apollo 13 mission astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide can remove carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. The astronauts have a 5 kg container of sodium hydroxide on the ship. The reaction to neutralize the air, remove carbon dioxide with sodium hydroxide is shown below CO2(g) + 2NaOH(s) ⟶⟶ Na2CO3(aq) + H2O(l) The astronauts have 2 days left before they land on earth. You know that there are three astronauts, and each astronaut emits roughly 500. g of carbon dioxide each day. Is there enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? Calculate how much sodium hydroxide is required to remove all the carbon dioxide from the three astronauts. Be sure to show all your work!
For the following reaction, 5.86 grams of carbon tetrachloride are mixed with excess methane (CH4). The reaction yields 5.93 grams of dichloromethane (CH2CI2). What is the percent yield of this reaction? CH4 + CCh --> 2CH2Cl2 27.6% 109.1% 91.65% 84.5%
Asprin can be made in a laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form asprin (C9H8O4) and acetic acid (C2H4O2). The balanced equation is: C4H6O3 + C7H6O3 ------> C9H8O4 + C2H4O2 In a laboratory synthesis, a student begins with 5.00 mL of acetic anhydride (density = 1.08 g/mL) and 2.08g of salicylic acid. Once the reaction is complete, the student collects 2.06g of asprin. Determine the percent yield for the reaction.
