While the calculation works just as planned, Watney makes an explosive mistake. In the movie, he fails to take into account the oxygen in the gas he's breathing out. Everything appears to be going well, but the laws of nature soon assert themselves — in the form of a fireball..
Similarly one may ask, what chemical does Watney use as a source of hydrogen for his production of water?
hydrazine
Subsequently, question is, how much food did Mark Watney have? Just to be safe, NASA sent 68 sols' worth of food, for six people. For Watney alone, that will last 300 sols, extended to 400 if he rations. Watney needs 1,500 calories every day. He has 400 sols' supply of food already.
Regarding this, what happened when Watney tried to make water?
Watney takes the risk of creating his own water by using his oxygenator (a device that creates oxygen from carbon dioxide), extracting hydrogen from the crew's unused hydrazine fuel (from the MDV, or Mars Descent Vehicle), and burning them to create the extra water he needs to nourish his potatoes.
How does the Martian relate to chemistry?
Chemistry, specifically the synthesis of water from hydrazine, is very important to the story of “The Martian”. Even without the plight of a marooned astronaut, chemistry is essential to the survival of humans on long space flights where carbon dioxide must be recycled into oxygen.
Related Question Answers
Can you make water from hydrazine?
2H2 + O2 -> 2H2O which is water. To put it simply, Mark Watney decomposed Hydrazine to produce H2. He then combined H2 with o2 to form H2O.Is Mars Hot or cold?
Overall, Mars is cold—its average global temperature is around -80 degrees Fahrenheit—and has a much thinner atmosphere than Earth. Because it has about a sixth of the pressure of Earth's atmosphere, the planet doesn't retain heat very long, causing temperatures to drop quickly.How does Watney make oxygen?
On Mars, Watney can't just step outside for a breath of fresh air To survive, he has to carry his own supply of oxygen everywhere he goes. The system produces oxygen through a process called electrolysis, which splits water molecules into their component oxygen and hydrogen atoms.Can you walk on Mars without a spacesuit?
Could you really survive outer space without a suit? Yes, for a very short time. The principal functions of a spacesuit are to create a pressurized, oxygenated atmosphere for astronauts, and to protect them from ultraviolet rays and extreme temperatures.How do you make hydrogen?
There are a number of ways to produce hydrogen: - Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam.
- Electrolysis: An electric current splits water into hydrogen and oxygen.
Why can't plants grow on Mars?
Therefore, under Martian gravity, the soil can hold more water than on Earth, and water and nutrients within the soil would drain away more slowly. Some conditions would make it difficult for plants to grow on Mars. Also, the Martian atmosphere is not as thick as Earth's atmosphere, which keeps our planet warm.Why is Mars red?
Mars is red now, but it may have looked like charcoal in the past. The simple explanation for the Red Planet's color is that its regolith, or surface material, contains lots of iron oxide — the same compound that gives blood and rust their hue.Is Mars soil toxic?
Toxicity. Martian soil is toxic, due to relatively high concentrations of perchlorate compounds containing chlorine. Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity.How does Watney survive?
He pierces the glove of his pressure suit and uses the escaping air to propel himself towards Lewis, effectively reuniting him with his crew after 560 sols alone on Mars. After returning to Earth, Watney becomes a survival instructor for astronaut candidates.What is hydrazine in?
Hydrazine is used in agricultural chemicals (pesticides), chemical blowing agents, pharmaceutical. intermediates, photography chemicals, boiler water treatment for corrosion protection, textile dyes, and as. fuel for rockets and spacecraft. (How does Mark Watney communicate with Earth?
So in order to gain contact with NASA, Watney digs up the Mars Pathfinder, the probe which NASA lost contact with in 1997. He fixes it (woo!) and the probe is able to communicate with Earth. Through a camera on the Pathfinder, Watney is able to speak to NASA through messages he writes and shows to it.How do we get water on Mars?
On Mars, water can be extracted from the soil. The rover will select the location for the settlement primarily based on the water content in the soil. We expect this to be at a latitude of between 40 and 45 degrees North latitude. Water extraction will be performed by the life support units.Could a plant survive on Mars?
Like customizing a car, NASA-funded scientists are designing plants that can survive the harsh conditions on Mars. These plants could provide oxygen, fresh food, and even medicine to astronauts while living off their waste. Also, the Martian soil is poor in the mineral nutrients necessary for plants to thrive.Why do they call it Sol in the Martian?
The term sol is used by planetary scientists to refer to the duration of a solar day on Mars. The term was adopted during the Viking project in order to avoid confusion with an Earth day. By inference, Mars' "solar hour" is 1/24 of a sol, and a solar minute 1/60 of a solar hour.How did Matt Damon make water in the Martian?
Making water Matt Damon's character took hydrazine from the rocket fuel and dissociated it into nitrogen and hydrogen, which you can do, and he burned the hydrogen with oxygen to make water.
