Hydrocarbons

according to me, ethane can't be prepared from ethanol.

but you can prepare ethene from ethanol by treating ethanol with conc.

H2SO4 (95%) In 440 K Temperature with release of water molecule.

by removal of hydrogen molecule one more pi bond will be formed between carbons thus ethene will convert in ethyne

Edit by some other dude named Timaeus:

Yeah...no. That's not right at all. This is how it's done:

First, halogenation of ethene to form a vicinal dihalide. Then a second order elimination reaction, let's say using a bulky nucleophile like tert-butoxide, to convert it to a bromoethene. Then just once more with the E2 reaction to form ethyne.

Neptune. That is why it has it's bluish color.

1) Bromination: add a drop or two of dilute bromine (Br2) to the sample, if the brown color disappears, it is an alkene, and...

2) Baeyer's Test: add a drop or two of potassium permanganate (KMnO4) to the sample, if the purple color disappears, it is an alkene.
hope that helped! :)

Butane gas is highly flammable and can explode if exposed to an ignition source. It is important to handle butane gas with care and follow proper safety procedures to prevent accidents. If butane gas leaks and accumulates in an enclosed space, it can pose a serious fire hazard.

Yes, addition reactions can take place in alkenes. Alkenes are typically reactive towards addition reactions because they contain π bonds, which can break to allow new atoms or groups to be added to the carbon atoms of the double bond. Examples of addition reactions in alkenes include hydrogenation, halogenation, and hydration.

Yes, a 100 pound propane tank can operate a gas log fireplace. However, the tank may need to be refilled more frequently compared to larger tanks. It's important to follow all safety guidelines and have the system installed and maintained by a professional.

Neptune and Uranus both have high concentrations of methane in their atmospheres.

The planet you are describing is Neptune. It is known for its blue-green color due to the presence of methane in its atmosphere. Neptune has layers of water, ice, methane, and ammonia in its atmosphere, and it also has the fastest recorded winds in our solar system, reaching speeds of up to 1,300 mph.

Yes, methane has been detected in the atmosphere of Mars by several instruments on spacecraft and telescopes. The presence of methane is significant because it could potentially be a sign of microbial life or geological activity on the planet. However, the exact source of the methane on Mars is still under investigation.

To hook a propane gas line to a gas furnace, you will need to connect the gas line to the furnace using approved fittings or connectors. It is important to ensure that the gas line is correctly sized for the furnace's gas requirements and that all connections are secure and leak-proof. It is advisable to hire a professional to install the gas line to avoid any safety hazards.

There are 4 moles of molecules in 2.4 moles of butane. One mole of butane contains Avogadro's number of molecules, which is 6.022 x 10^23. Therefore, 2.4 moles of butane will contain 2.4 x 6.022 x 10^23 molecules.

Are you referring to tank price or bulk price? Tanks - small ones like your grill takes are about $25 most places. Bulk propane is sold by the pound and price can vary widely. If you have a contract it may be $17 a pound. Without one, it can be more.

A halogenated hydrocarbon is a compound that contains halogen atoms (fluorine, chlorine, bromine, or iodine) covalently bonded to carbon atoms. These compounds are used in various industrial applications, but some are also considered environmental pollutants due to their toxicity and potential for bioaccumulation. Examples include chlorofluorocarbons (CFCs) and polychlorinated biphenyls (PCBs).

A propane furnace likely uses more propane than a propane fireplace as it is responsible for heating the entire home whereas a propane fireplace is generally used for supplemental heating or ambiance. Furnaces are designed to operate continuously for long periods of time, leading to higher propane consumption compared to fireplaces which are used intermittently.

Transparent like liquid water. However if viewed from a bird's eye view the lakes would appear orange for the same reason that oceans on Earth appear blue, because it refelects the color of the atmosphere.

First of all, methane (CH4) is explosive. It's not merely flammable in its gaseous state. Methane, though not toxic, can displace oxygen and an individual in a methane infiltrated environment can asphixiate. It is also rates fairly high as a greenhouse gas, and its on the list of "bad" things in the atmosphere that contribute to the increase in the rate at which the earth is warming. A link can be found below.

Uranus and Neptune have large relative amounts

Jupiter and Saturn have a small percent of methane

The amount of propane an outdoor lamp uses can vary depending on factors such as the size and output of the lamp, how long it is used each day, and the intensity of the flame. On average, a typical outdoor lamp with a standard propane tank can burn for about 10-12 hours on a one-pound propane cylinder.

Hydrocarbons have high energy content due to their carbon-carbon and carbon-hydrogen bonds, making them excellent fuel sources. They release energy when combusted, producing heat and carbon dioxide as byproducts. This energy release can be harnessed for various applications, such as powering vehicles and generating electricity.

There are many two carbon molecules but the most simple one is ethylene (C2H4)

Burning propane (C3H8) involves the chemical reaction of propane with oxygen to produce carbon dioxide (CO2) and water vapor (H2O), releasing heat energy in the process. This combustion process is used in appliances like stoves, water heaters, and furnaces for heating and cooking purposes. Proper ventilation is essential to ensure complete combustion and to prevent the accumulation of harmful byproducts like carbon monoxide.
