You are a NASA engineer. You are the chief engineer for the Apollo 13 mission to the moon. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide (NaOH) has been suggested as a means of removing carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. You remember that the astronauts have a 5000. g container of sodium hydroxide on the ship. You also know that sodium hydroxide can be used to remove carbon dioxide.

Use the following reaction: NaOH + CO2 → Na2CO3 + H2O

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? SHOW ALL YOUR WORK - DON’T FORGET TO BALANCE THE EQUATION

Guiding Questions: How many grams of CO2 are produced in a day? How many grams of CO2 are produced in both days? How many grams of NaOH do you need to get rid of 3000 g of CO2?

Sagot :

Answer:

We know that there are three astronauts and each one of them emits 500 grams of carbon dioxide each day, so the total carbon dioxide emitted each day.

Explanation:

From the mole ratio of the reaction, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon

What was of Sodium hydroxide is required?

The mass of sodium hydroxide required depends on the mass of CO2 produced by the astronauts.

The mass of CO2 produced by the astronauts is calculated as follows;

Mass of CO2 produced = 3 × 2 × 500 g = 3000 g of CO2

The mass of sodium hydroxide required is calculatedfrom the eqaution of the reaction given below:

  • [tex]2NaOH + CO_2 → Na_2CO_3 + H_2O \\ [/tex]

2 moles of sodium hydroxide reacts with 1 mole of CO2

Molar mass of NaOH = 40 g/mol

Molar mass of CO2 = 44 g/mol

Mass of sodium hydroxide required = 3000 g × 2 × 40/44 = 5454.54 g

Therefore, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon.
