a typical steel "30 pound" liquid propane tank weighs about 25-28 pounds empty.
propane tank markings (on collar)
propane weighs about 4.125 pounds per gallon and a "30 pound tank" will
hold about 7.5 gallons so a full tank will weigh about 55 pounds or so.

This is because they have a large number of hydrogen atoms attached to the carbon atoms
Alkanes (also known as paraffins or saturated hydrocarbons) are chemical compounds that consist only of the elements carbon (C) and hydrogen (H) (i.e., hydrocarbons), wherein these atoms are linked together exclusively by single bonds (i.e., they are saturated compounds) without any cyclic structure (i.e. loops). Alkanes belong to a homologous series of organic compounds in which the members differ by a constant relative molecular mass of 14.
Each carbon atom must have 4 bonds (either C-H or C-C bonds), and each hydrogen atom must be joined to a carbon atom (H-C bonds). A series of linked carbon atoms is known as the carbon skeleton or carbon backbone. In general, the number of carbon atoms is often used to define the size of the alkane (e.g., C2-alkane).
An alkyl group, generally abbreviated with the symbol R, is a functional group or side-chain that, like an alkane, consists solely of single-bonded carbon and hydrogen atoms, for example a methyl or ethyl group.
The simplest possible alkane (the parent molecule) is methane, CH4. There is no limit to the number of carbon atoms that can be linked together, the only limitation being that the molecule is acyclic, is saturated, and is a hydrocarbon. Saturated oils and waxes are examples of larger alkanes where the number of carbons in the carbon backbone tends to be greater than 10.
Alkanes are not very reactive and have little biological activity. Alkanes can be viewed as a molecular tree upon which can be hung the interesting biologically active/reactive portions (functional groups) of the molecule.

depend where you are coming from i would say with this economy about $200.00
Oil is located under the ground. You recover it by drilling down and creating an oil well. Petroleum is refined from oil.
HYDROCARBAN use in different industries like HC use in manufacturig different synthetic rubber ..
Plastic pipe is allowed per 2006 Uniform Plumbing Code (current as of 2010) for underground exterior applications of LP gas (propane, butane, natural gas...). The pipe must be per ASTM D 2513. When you apply for your permit, the local jurisdiction will tell you what you can/can't use for your particular situation.
Nomex is not a brand name of Kevlar. Nomex and Kevlar are both trademarked names for different, although similar, composite fibers. They are both ring compounds based on benzene. The difference is that Kevlar has para-oriented aromatic rings, making it about five times stronger than Nomex. Nomex has meta-oriented rings with 120-degree bond angles, which helps it not melt at high temperatures. That's why Kevlar is used for bullet-proof vests and Nomex is used for firefighter uniforms.

The gas Methane is not Toxic , however it is highly flammable and can form many explosive mixtures with air. It's violently reactive with oxidizers, halogens, and some halogen-containing compounds. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia may result if the oxygen concentration is reduced to below 19.5% by displacement. When structures are built on or near landfills, methane off-gas can penetrate the buildings' interiors and expose occupants to significant levels of methane.
Yes. A hydrocarbon is an organic compound containing only carbon and hydrogens. Propane has the molecular formula of C3H8.
All those gases which have molecular mass less than 28 are lighter than air as H2,He,CH4,and Ne.
hydrocarbons are not soluble in a polar solvent but are soluble in a non-polar solvent.
The temperature of a propane flame is theoretically about 2,000 °C (3,600 °F) but may be lower in practice, due to various factors (fuel/air mixture, flow rate, humidity, etc.).
Methane reacts with oxygen in the following way. CH4 + 3 O2 --> CO2 + 4 H2O. If 5 moles of oxygen react with 2.8 moles of methane, only 1.67 moles of methane would be consumed because of the molar ratio 1:3. This would produce 1.67 moles of carbon dioxide and 6.67 moles of water.
No. you have to change the nozzles for the burners and for the stove portion. The replacement nozzles generally come on the rear of the stove upper right or left corner on a small 2" strip. the nozzles are small with 6flat sides to allow tightening with a wrench. to gain access to the nozzles for the range top generally you have to lift the top,remove the burner, unscrew the propane nozzle and attach the natural gas nozzle. the natural gas nozzle has a larger orifice to allow the gas to pass through to the actual burner. the stove is a bit more complicated but can be done by anyone who is semi mechanically inclined.
the chemical formula of methane is CH4. one molecule of methane contains one carbon atom and four hydrogen atoms.
Alkynes always form a triple bond. This being so, essentially, all you have are the two carbon molecules and the triple bond! No matter what way your turn it, or how you look at it, even if in a mirror (ie. optical isomerism) you will always have the same looking molecule while to have a geometrical isomer cis or trans form should be there.
gen equation for a compound to be a geometrica isomer:
1.YXC = CXY
2.YXC = CXZ
Butyne is not a molecule. Butyne 1 is classified as an alkaline and is colorless gas. Butyne is very flammable and has a boiling point of 8.08 degrees Celsius.
CH4 is the formula for methane
methane is hyrdorcarbon. oil is also a hyrdocarbon. the interaction between the two is Van der Waal forces. no other secondary bonding is present to hinder or weaken the Van der Wall forces
An alkane feed is contacted at sub-atmospheric pressure and at an elevated temperature with a preheated charge of Chromic Oxide-alumina catalyst in a fixed bed reactor. Carbon is deposited on the catalyst as the reaction proceeds. In order to provide the necessary heat of reaction it is usual after a short while to switch the alkane feed to another reactor whilst the catalyst of the first mentioned reactor is regenerated by burning off the deposited carbon with hot air.
