What is the chemical name for aspirin?
2-Acetoxybenzoic acid
Can methane kill you?
In severe cases, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness. If exposure is large or continues for a longer period it can kill. Skin or eye contact with liquefied methane released under pressure may cause frostbite. Methane is not thought to cause cancer in humans.
How is methane written?
Formula and structure: The methane chemical formula is CH4 and is also written as Met. Its molar mass is 16.043 g mol-1. The molecule is the simplest organic compound and it is considered the base of more complex organic molecules. The methane molecule has a tetrahedral geometry with 4 hydrogen bound to a carbon atom.
What are the chemical products of burning methane?
The main products formed in the oxidation of methane at 300-450° C are methyl alcohol, formaldehyde, formic acid, carbon monoxide, carbon dioxide and water (Bone and Wheeler 1903; Bone and Allum 1932).
Why is methane not used as fuel?
Methane’s relative abundance and clean burning process makes it a very attractive fuel. However, because it is a gas and not a liquid or solid, methane is difficult to transport from the areas that produce it to the areas that consume it.
Is methane a clean burning fuel?
Natural gas, which primarily consists of methane, is the cleanest burning fossil fuel. However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change.
Is liquid methane dangerous?
Safety. Methane is nontoxic, yet it is extremely flammable and may form explosive mixtures with air. Methane is also an asphyxiant if the oxygen concentration is reduced to below about 16% by displacement, as most people can tolerate a reduction from 21% to 16% without ill effects.
Can liquid methane support life?
It has been speculated that life could exist in the liquid methane and ethane that form rivers and lakes on Titan’s surface, just as organisms on Earth live in water. By comparison, some methanogens on Earth obtain energy by reacting hydrogen with carbon dioxide, producing methane and water.
Can humans drink liquid methane?
Methane is non-toxic, but it is explosive. And, at very high concentrations, it can cause death by asphyxiation (since there isn’t enough oxygen to get to your lungs). In the chart, the worst sample had 70 mg of methane per liter of drinking water.
Can liquid methane freeze?
Our recent work has shown that although methane and ethane have similar freezing points (~91 K), when mixed they can remain liquid down to 72 K.
How cold is liquid oxygen?
Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below -238°F (-150°C). Liquid oxygen has a boiling point of -297.3°F (-183.0°C).
What Colour is liquid methane?
yellow
What moon has liquid methane?
Titan’s
Why is there no life on Titan?
Titan is not a pleasant place for life. It is far too cold for liquid water to exist, and all known forms of life need liquid water. Titan’s surface is -180°C.
Does it rain on Titan?
Titan’s atmosphere is made mostly of nitrogen, like Earth’s, but with a surface pressure 50 percent higher than Earth’s. Titan has clouds, rain, rivers, lakes and seas of liquid hydrocarbons like methane and ethane.
Can a person live on Saturn?
Without a solid surface, Saturn isn’t likely a place we could ever live. But the gas giant does have numerous moons, some of which would make fascinating locations for space colonies, particularly Titan and Enceladus.
Why is Titan so cold?
Temperature. At this temperature water ice has an extremely low vapor pressure, so the atmosphere is nearly free of water vapor. However the methane in the atmosphere causes a substantial greenhouse effect which keeps the surface of Titan at a much higher temperature than what would otherwise be the thermal equilibrium …
Can you land on Saturn?
As a gas giant, Saturn doesn’t have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn’t be able to fly through unscathed either.
Has anyone been on Uranus?
The only spacecraft to ever visit Uranus is the Voyager 2 probe. The Voyager 2 probe was launched on August 20, 1977 and reached Uranus on January 24, 1986.
Why can we not live on Neptune?
Neptune’s environment is not conducive to life as we know it. The temperatures, pressures and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Could a human survive on Neptune?
The answer is that we couldn’t live on the planet Neptune for a few reasons. It’s far too cold, there’s no oxygen and it’s primarily made up of ice! So, it’s not going to be suitable for colonization by humans any time soon, even though it is within our solar system.
