Hydrocarbons

Increasing the number of resonance structures increases the delocalization of electrons, spreading the positive and negative charges over a larger area. This increased delocalization results in lower overall energy and increased stability of the molecule.

The subscripts in the formula for ethane (C2H6) represent the number of atoms of each element in the compound. In this case, "C2" indicates there are 2 carbon atoms, and "H6" indicates there are 6 hydrogen atoms in one molecule of ethane.

Water vapor comes from space, the ocean / lakes / rivers, and from respiration / combustion of fuels with hydrogen in them. In no particular order. Carbon dioxide comes from space, from / to the ocean, and from respiration / combustion of fuels with carbon in them. In no particular order. Methane comes primarily from biological decomposition of organic materials. Ozone is produced by oxygen broken apart either by electrical discharge, UV-C from the Sun, or by photoproduction involving NOx and unburned fuel.

Isomerisation causes straight chain alkanes to become branched alkanes which prevents the chains from moving to close proximities of each other. This reduces the van der Waal's intermolecular forces between chains so less energy is needed to overcome the forces and thus a lower boiling point.

It is not clear what you mean by 'trap'. It contains chemical energy which can be released by burning, giving 55.5 MJ per kg. You may however be referring to the ability of the substance to absorb heat, i.e. its heat capacity. This is the amount of energy absorbed when the temperature of the substance increases by 1 degree Kelvin. This is 2.087 kJ/kgK at 200 K. (It varies a little with temperature.)

At normal pressure, the alkanes pentane (C5H12) through decane (C10H22) are liquids. Alkanes are organic compounds consisting of a single carbon chain of single covalently bonded carbon atoms surrounded by hydrogen atoms.

1gal. Propane = 91600 BTUs

1gal. Kerosene = 135000 BTUs

To heat 1,000,000 BTUs it would cost:

10.91 gals of Propane x (price per gal) = Cost (to heat 1mil btu)

7.4 gals of kerosene x (price per gal) = Cost (to heat 1mil btu)

Remember this is at 100% efficiency.

If you are working with something less efficient you must multiply the fuel btu by the efficiency.

For example:

Propane Furnace that is 80% efficient.

1,000,000 / (91600 x .8) = 13.6 gals

13.6 gals x (price per gal) = Cost (to heat 1mil btu)

Kerosene furnace that is 60% efficient.

1,000,000 / (135,000 x .6) = 12.3 gals

12.3 gals x (price per gal) = Cost (to heat 1mil btu)

Hope this helps

good luck

By pouring hot water on a propane cylinder you are heating the metal cylinder. The liquid propane in the cylinder is cold and forms condensation on the outside of the cylinder showing the level of propane remaining in the tank much like condensation forming on a glass of ice water on a hot day.

TET indicates the product is in the Texas Eastern Products Pipeline at Mont Belvieu Texas. Non TET refers to product in a location at Mont Belvieu other than in the Texas Eastern Products pipeline. Such as independently owned storage facilities, Velero or Targa.

C5H10 can be both an alkane and an alkene. As an alkane, it would be pentane (C5H12), and as an alkene, it would be 1-pentene (C5H10). The presence or absence of a double bond in the molecule determines if it is an alkane or an alkene.

In general, yes. The average propane torch will be more than adequate to do the job, as long as the block of silver isn't too large or the torch too small. Silver melts at 961.78 °C, or 1763.2 °F, and the propane torch can burn at something close to 1000°C.

The formula for a hydrocarbon is CnH2n+2

THE QUESTION DOES NOT QUITE GIVE ALL INFO NECC. FOR AN ACCURATE ANSWER, HOWEVER: IF THE LP APPLIANCE VENTS OUTSIDE, ANSWER IS YES. IF AN UN VENTED TYPE, MAYBE. INFRARED CATALYTIC HEATERS ARE VERY EFFICIENT IN THAT THEY PRODUCE VERY LITTLE CARBON MONOXIDE. THE DOWNSIDE IS THE POTENTIAL FOR OXYGEN DEPLETION THIS OCCURS IF THE SPACE BEING HEATED IS SMALL OR OF TIGHT CONSTRUCTION IN THAT THEY WILL USE THE O2 IN THE SPACE, AND LEAVE A LIMITED AMMOUNT FOR YOUR FAMILY OR ANIMALS TO BREATH. MANY LOCAL JURISTICTIONS PROHIBIT THEIR USE. MOST CURRENT PRODUCTION TYPES DESIGNED FOR RESIDENTIAL AND RECREATIONAL USE HAVE WHAT IS CALLED AN "OXYGEN DEPLETION SENSOR". THIS MAY BE WHAT IS COMMONLY CALLED AN "ODP". THIS PILOT EXTINGUISHES ITSELF AS THE OXYGEN LEVELS DECREASE. THIS IN TURN KILLS THE VOLTAGE PROVIDED BY THE THERMOCOUPLE TO THE GAS VALVE, ETC. I HAVE USED THE "GLO-WARM" BRAND IN MY MOTORHOME FOR SOME TIME WITH GOOD RESULTS. NEVER HAD A SHUTDOWN ON OXYGEN ISSUES. A CARBON MONOXIDE DETECTOR WOULD BE ADVISED IN ANY APPLICATION INVOLVING FOSSIL FUEL APPLIANCES. lc

As long as your house stove is not running off of natural gas (a pipeline routed through your neighborhood with a big meter on the side of your house = natural gas). If your house has a big huge gas tank on the side of it, it is propane, and that is what those bottled gas things are that you buy at the gas station. Disconnect the gas line at the huge tank outside your house, and connect the small tank you got at the gas station directly to the line right there. I have done it myself before, and I am also a plumber with experience in working and installing gas lines.

Butane and isobutane are isomers or compounds that have the same chemical fomula but different structual formulas.

The chemical symbol for methane is CH4.

ethene: CH2=Ch2

propene: CH2=CH3CH

There is nowhere else to place a double bond! (C=C)

No number is used in the names ethene and propene because the number would be useless as the double bond is located at carbon "1"

The conversion of a natural gas appliance for use with propane involves replacing the jets that regulate the rate of flow of the fuel. Natural gas and propane have different abilities to deliver heat energy when they burn. Propane, a product of petrochemical refining, has more heat energy per cubic foot, about 13.8kWh, than does natural gas, a petroleum gas that is extracted directly from the ground, and has about 10.8kWh of energy per cubic foot. What that means in this case is that the jets will have to be replaces with ones that have a smaller hole in them. This allows the burners to deliver the same performance with propane as they did with natural gas. IMPORTANT! Failure to replace the jets with the proper ones for the new fuel will cause the range to run hotter than its designers engineered it for! Don't fool around with this one. A fire could cost you the structure in which the range is operated if you don't do things right. Of course that wouldn't matter much to you if you were unfortunate enough to be inside when it burned down. A word to the wise is sufficient. Call your propane supplier and get the straight scoop. They're the experts.

Propane truck drivers typically earn an average annual salary of around $40,000 to $60,000, depending on factors such as experience, location, and company. Additional benefits, such as healthcare and retirement plans, may also be included in their compensation package.

The net chemical equation for the production of hydrogen from propane and water is:

C3H8 (propane) + 3H2O (water) -> 3CO2 (carbon dioxide) + 7H2 (hydrogen gas)

N-heptane is a specific isomer of heptane, while heptanes refer to a mixture of isomers of heptane. N-heptane has a linear structure, while heptanes can contain branched isomers in addition to n-heptane.

Balanced equation.

2C4H10 + 13O2 -> 8CO2 +10H2O

8.13 grams C4H10 (1 mole C4H10/58.12 grams)(10 moles H2O/2 mole C4H10)(18.016 grams/1 mole H2O)

= 12.6 grams water produced

Alkynes are a similar functional group to alkanes and alkenes.

The difference is that alkynes have a triple bond between two carbon atoms.

The most well known alkyne is Ethyne (Acetylene) .

Its structure is H-C///C-H . This gas is used in oxy-acetylene burners, and produces a very hot flame to melt metals.

Other alkynes are

Propyne ; H-C///C-CH3

But-1-yne ; H-C///C - CH2-CH3

But-2-yne ; H3C-C///C-CH3

Be careful when spellings these chemcial names , there is only ONE letter difference. alkAne, alkEne, & alkYne.

As a rule, your propane tank will hold 80% of its designated capacity, therefore, a 500 gallon tank would hold 400 gallons.

However, the 80% rule is based on expansion and contraction due to temperature. Propane expands in warmer weather.

In cold temperatures you can fill to over 90% capacity (450+ gallons) but you should plan on using a portion of that propane before the weather turns warm or pressure could build as temperatures rise, thereby opening the pressure relief valve and releasing gaseous gold into the atmosphere! The hazard could be worse than the expense.

Note: Some tanks are rated in pounds vs gallons. A 100 pound tank would hold just under 25 gallons.
