Hydrocarbons

A formation equation is something like this: H2 + 0.5O2 --> H20. Formation equations are the only case in which a formula can have fractions, this is because the product must have one mol of the compound. In the case of Ammonia:

Hydrogen reacts with Nitrogen to form Ammonia:
H2 + N2 --> NH3 [incorrect]
3/2 H2 + 1/2 N2 --> NH3 [correct]

That is the equation for the formation of Ammonia

Ethane cannot be directly prepared from iodoethane. However, iodoethane (also known as ethyl iodide) can be converted to ethane through a series of chemical reactions involving dehydrohalogenation or Wurtz reaction. This typically involves using strong bases like sodium or potassium hydroxide to remove the iodine atom from iodoethane and convert it to ethane.

Pentane would look something like this:

H3 - C - CH2 - CH2 - CH2 - C - H3

giving it a formula of C5H12 consistent with the formula CnHn+2, which is used for determining the formula of any 'n' - ane.

No, hydrocarbons contain carbon (C) and hydrogen (H)

NH3 is a compound of nitrogen and hydrogen.

The term "20 lb." refers to the weight of propane that the tank can hold when filled to its maximum capacity. The tank itself, when empty, may weigh around 18-20 pounds, hence the designation as a 20 lb. propane tank.

Yes, 3-hexene can exist as cis-3-hexene and trans-3-hexene isomers. In the cis isomer, the two alkyl groups are on the same side of the double bond, while in the trans isomer, they are on opposite sides.

A Crude mixture is a mixture that has more than one kind of atoms in it. For example if you were to shrink down to a tiny size and run through the sand its not all the same sand theres many different types just like atoms.

Both Uranus and Neptune do, giving them a blue colour (bluish green for Uranus).

Benzene will not decolourise bromine water as it does not undergo addition reaction. It is highly saturated due to presence electron cloud above and below it.

Inhalation of bleach can cause severe internal damage, including deterioration of the esophagus lining and lungs. Scarring of the respiratory tract can also occur.Exposure to high concentrations of bleach can result in eyes burning, nose irritation and coughing. Exposure to extremely high levels of bleach, such as 500 ppm (a concentration significantly greater than household bleach), could result in respiratory damage, chronic bronchitis and airway hyperactivity. In some cases, death can occur. Always wear the appropriate equipment and protective masks when working near high concentrations of bleach. According to the Hazardous Substance Emergency Events Surveillance, a report published by the state of Maine, you should always report any symptoms that may occur, including coughing, nausea, shortness of breath, watery eyes, chest pain, irritation to the throat, nose and eyes, and wheezing,

Propane's scientific name is propane.

Hissing is the most common sound to come from propane tanks and is usually a sign of a gas leak. If you hear this noise you should turn your tank off and immediately call your propane supplier for a technician

When hydrocarbon fuel burns in plenty of air, complete combustion occurs, producing carbon dioxide and water as the main substances. Incomplete combustion due to limited air can produce carbon monoxide, soot, and other harmful byproducts along with carbon dioxide and water. The specific substances produced depend on the type of hydrocarbon fuel and the combustion conditions.

The process you are referring to is known as cracking. Cracking involves breaking down larger, less valuable hydrocarbons into smaller, more valuable hydrocarbons such as gasoline and diesel. This process improves the quality and effectiveness of the fuel produced.

The atoms in a molecule of methane are held together by covalent bonds. In methane, a carbon atom is bonded to four hydrogen atoms through sharing of electrons, forming a stable structure. These covalent bonds provide the necessary attraction to hold the atoms together in a molecule.

An aromatic compound contain a benzene ring.

In carbondioxide:

CH4 + 3 O2 ==> CO2 + 2 H2O

Methane from waste is burned to convert it into carbon dioxide, which is less potent as a greenhouse gas. This process helps to reduce the environmental impact of methane emissions on climate change. Additionally, burning methane can also be used to generate energy in the form of heat or electricity.

High resistivity is the inverse of conductivity, and Carbon is not a good conductor (although it could be a better conductor than most hydrocarbons). Here are a few examples:

Carbon - 0.07 x 106 S cm-1 (not a good conductor)

Silicon - 1.2 x 10-5 S cm-1 (not a good conductor - used for this purpose in microchips)

Copper - 59.6 × 106 S cm-1 (good conductor)

Atoms in metals (good conductors) are held together by bonds between nuclei and their electrons. Atoms in nonmetals (bad conductors) are held together due to the atmos' sharing of valence electrons (ie covalent bonds).

Conductivity has to do with how easily electrons can move. In metals, electrons are more free to move than nonmetals, resulting in better conductivity. Silver is the best conductor, I believe. Sorry for the run around, but the basic answer to your question is this: I suspect in hydrocarbons, the valence electrons are more restricted due to the covalent bonding to the hydrogen atoms.

Well, when burning hydrocarbons in complete combustion, the products are Water (H2O) + Carbon Dioxide (CO2). The only potentially dangerous product of complete combustion of hydrocarbons is CO2 in large amounts which some people believe presents a danger of global warming.

However, if you are referring to incomplete combustion then the products are Water (H2O) + Carbon Dioxide (CO2) + Carbon Monoxide (CO) + Soot (C). Now CO is very dangerous and suitably nicknamed the silent killer. It is heavier than air so it sinks to floor level. Also it is invisible to the human eye. It is dangerous because it will bind to the hemoglobin in the red blood cells stopping them from carrying oxygen - which will starve you of oxygen and kill you.

Using hydrocarbons as fuels also presents the problem of fuel that does not burn and enters the atmosphere as a vapor along with the exhausted gases from the fuel that did burn. Unburned gasoline (petrol) vapor, when exposed to sunlight, will form what are called "radicals" which will react with the air to produce ground-level ozone. Ironically while ozone in the high atmosphere helps protect plants and animals (and people) from the harmful effects of UV radiation from the sun, ozone at ground level is destructive of plants and attacks tissue in the lungs of animals.

An additional problem is that we usually burn hydrocarbons with air, not just pure oxygen. Since air is about 78-79% nitrogen (N2), there is plenty of N2 in the flame. The nitrogen also reacts with the oxygen at the high temperatures of combustion (it isn't much prone to the reactions at normal atmospheric temperatures) to form different nitrogen compounds referred to collectively as NOx. The "x" in NOx just means that it could be any one of several numbers - thus it includes NO, NO2, N2O, N4O, NO3, N2O3, N2O4, N2O5, N(NO2)3. N2O is pretty stable in the air but fortunately is only produced in very small amounts. Since N2O is also known as "laughing gas" you can decide for yourself it this is good or bad. NO and NO2 are fairly reactive. NO3 is highly reactive. The other compounds tend to decompose fairly quickly. All of the reactive and decomposing compounds can decompose or react with the atmosphere to form other compounds that are not too friendly to plants, animals, fabrics, metals, and masonry. NO2 is a brown gas and a the primary component of Smog - that brown haze that hangs over some cities.

The original answer incorrectly suggested that CO2 would damage the ozone layer and thus lead to global warming. CO2 has no effect on the ozone layer. Also, the ozone layer has no significant effect on global warming.

The general formula for unsaturated hydrocarbons is CnH2n. Examples include alkenes and alkynes.

The general formula of a saturated hydrocarbon is CnH2n+2, where n represents the number of carbon atoms in the molecule.

The gas that is taken from the air and converted to glucose in photosynthesis is carbon dioxide (CO2). Through the process of photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
