Hydrocarbons

No, I've never seen one yet without ethanol.

The density of methane at 20 degrees Celsius is approximately 0.656 kg/m³, and at 120 degrees Celsius, it is around 0.333 kg/m³. As temperature increases, the density of methane decreases due to the expansion of gas molecules.

Graphite.

You might have come across experiments using a pencil to complete a simple circuit to check if a bulb glows and you might have observed that it does.

The graphite in the lead of the pencil is what helps conduct electricity.

The hydrocarbon methane consists of a carbon atom bonded to four hydrogen atoms arranged in a tetrahedral shape. That its, the bonds to the hydrogen atoms point to the corners of a triangular pyramid. Use the link below to see an image that should help lock it in.

Typically, a 30 lb propane tank can last between 18-22 hours when used at a medium setting. However, actual service life can vary depending on the specific usage and conditions of use. Regular maintenance and inspections can also affect the tank's lifespan.

The atomic mass unit (amu) of propene (C3H6) is calculated by adding the atomic masses of the constituent elements: carbon (C) has an atomic mass of about 12.01 amu, and hydrogen (H) has an atomic mass of about 1.01 amu. Therefore, the calculated amu of propene is approximately (3 * 12.01) + (6 * 1.01) = 42.08 amu.

I would be verycareful playing about with gas heaters without the appropriate knowledge. different types of gas heaters have different hardware associated with them. You run a definite risk of blowing your self or worse your family to kingdom come.

The temperature of liquid butane sprayed into the air will rapidly decrease as it expands and evaporates, causing it to cool down. This process is known as evaporative cooling, where the liquid absorbs heat from the surroundings in order to transform into a gas.

A liquid refrigerant tank is used to store refrigerants that are used in air conditioning and refrigeration systems. These tanks are designed to handle specific refrigerants and are typically used in industrial and commercial settings.

A propane tank, on the other hand, is used to store propane gas, which is commonly used for heating, cooking, and as a fuel source for vehicles. Propane tanks are typically used in residential, commercial, and outdoor settings.

If the system is gas tight and the unit is "functioning correctly", the main reason for odor is the supply tank is either old and low on fuel, or it can be newer but has been filled by a supplier that pumped out old tanks recently. The odorant is an additive and will tend to boil out of the fuel and collect at the bottom of the tank over many years of use so when the level gets low it is more pungent.

Alkenes have pi bonds that are readily available to react because the strength of a pi bond isn't as strong as a sigma bond. Pi electrons will attack the nucleophile to form the respective carbocation. Alkanes only contain sigma bonds and have no pi electrons to attack a nucleophile. In order for an alkane to become a strong enough nucleophile it must not be sterically hindered (primary carbons prefered to tertiary) and most likely deprotenated by a very strong base ( likely stronger than sodium amide ).

Yes, a propane pilot light produces as much carbon dioxide per hour as a human being does per hour. Both human respiration and burning propane release carbon dioxide as a byproduct of the combustion process.

However, this figure is quite approximate as gasoline expands with temperature. A gallon of gasoline weighs around 6 pounds (US) but can approach 5 pounds in extreme heat. (Buying gasoline in the summer in Phoenix or Houston gives you less energy per dollar than you are paying for.)

Psst! Come in close for this one. There is a secret here.

Natural gas, that stuff the utility company pumps into your home, with which you heat the house, water, and cook. That is primarily methane, essentially the same stuff as the stink that comes from manure piles, and is locked in the sea bed. That stuff that the Greenies were complaining about a few years ago was adding to global warming (cow flatuence).

In short, yes, methane is a very renewable resource.

The plus and minus symbols are used to represent positive and negative charges, respectively. In the case of electrons, the minus sign indicates that electrons have a negative charge. This convention helps distinguish between different types of charges in physics and chemistry.

A 16 oz propane tank can typically last for about 1 to 2 hours, depending on the BTU rating of the device that it is fueling. This can vary based on the intensity of use and the specific appliance being used with the tank.

The lower explosive limit (LEL) of a hydrocarbon product is the minimum concentration of vapor in the air that is needed to create an explosive mixture. It varies depending on the specific hydrocarbon product but typically falls between 1-5% of the air by volume. Operating within safe limits is crucial to prevent the risk of explosions.

When rich gas is produced from a petroleum reservoir and processed in a surface separator, hydrocarbon liquids such as ethane, propane, butane, pentane, and heavier hydrocarbons can be recovered. These liquids are separated from the natural gas due to differences in their boiling points and compositions, and they are typically referred to as natural gas liquids (NGLs).

Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.

Lewis dot diagrams represt the outer shell electrons covalently sharing between elements. For NF3 it would it would be pyramidal. Nitrogen has 5 outer shell electrons therefore you would attach the 3 fluorine atoms to the three outer shell electrons on the nitrogen. Then that leaves you with one non-bonding pair.

Yes, animal manure contains methane. Methane is produced during the decomposition of organic matter in manure by anaerobic bacteria. Proper manure management practices can help reduce methane emissions.

Hydrocarbon deposits are natural reservoirs of fossil fuels such as oil and natural gas. These deposits are formed over millions of years from the remains of plants and animals that have undergone geological processes to become concentrated underground in rock formations. They are a major source of energy for human society.

Anything involving propane also likely involves an open flame. Be sure to read and obey all the safety restrictions in the instructions about the fire bowl since it could easily set fire to furniture, curtains, the porch roof, people's clothing or even your house.

This is a big issue now a day as scientists discovers new global warming threat as melting permafrost releases millions of tons of a gas 20 times more damaging than carbon dioxide. Underground stores of methane are important because scientists believe their sudden release has in the past been responsible for rapid increases in global temperatures, dramatic changes to the climate, and even the mass extinction of species.

An unsaturated hydrocarbon is a type of hydrocarbon molecule that contains at least one carbon-carbon double or triple bond. This means that the molecule does not have the maximum number of hydrogen atoms bonded to each carbon atom. Examples include alkenes and alkynes.
