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.
Typical recertification stamp:
MM XXX YY E
MM -> 2 digit recertification month
XXX ->3 character Re-qualifier's registration number
YY -> 2 digit recertification year
E ->States the cylinder has been externally examined
WC -> Water capacity of the cylinder.
TW -> Tare weight of the cylinder (what the tank weighs empty)
ICC, DOT, BTE, CTC or TC -> Specification number eg. TC4BA240
10 89 -> Date of manufacture (October. 1989)

Alternating single and double bonds
Asked by Wiki User
Cis/Trans Isomerism occurs when there are two different groups on each side of the C=C bond. In But-2-ene the Carbons with a double bond are each bonded to one C and one H whereas, in But-1-ene one end is bonded to carbon and Hydrogen, and one end is bonded to two hydrogens.
H [CH2]- CH3

C=C But-1-ene: One end bonded to two Hydrogens, One end bonded

H3C CH3 (Carbon) are both on same side so cis or Z

This is because they have a large number of hydrogen atoms attached to the carbon atoms
Asked by Wiki User
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.

The fuel is refined from hydrocarbon liquids and gases derived from wells drilled deep into the Earth's crust. Those hydrocarbons were/are derived from far deeper sources in the mantle. My theory is that at certain as yet undiscovered levels of the mantle, the temperature and pressure are ideal for elemental carbon and hydrogen to combine. Over time, these hydrocarbons seep up into the crust where we find them. The ones from the deep oceans are the purest because they have not yet been exposed to the organic contamination found either in shallower seas or on terra firma.

Butadiene is a non-corrosive gas that condenses to a liquid and is used to make polymers. Butadiene polymers include neoprene, styrene-butadiene rubber, and nitrile rubber.

Ethanol is a compound, not an element and so does not have an atomic number. It is composed of the elements carbon, hydrogen, and oxygen which have the atomic numbers 6, 1, and 8 respectively.
Asked by Wiki User
If by hydrocarbons you mean fossil fuels like oil and natural gas, yes, they can be. However, without hydrocarbons, life would be very much more difficult and there would be a lot fewer humans.
Hydrocarbons, typically, are not highly poisonous. Natural gas can displace oxygen in high concentrations and cause suffocation, and petroleum distillates can irritate digestive tissues if swallowed, and cause edema if inhaled.
Their main danger is that they are flammable. Natural gas explosions kill hundreds of people every year, and many others are burned by distillate fires.
Another danger in rich countries is hydrocarbons reduce, sometimes sharply, the amount of exercise people get, leading to diseases like diabetes and hypertension.

Primary standard is a chemical entity available with highest purity and stability with high molecular weight. e.g. KHP, NaCl, Calcium salt used in standardisation of volumetric solution.
Secondary standards are compounds used in analysis after evaluation against primary standards. e.g.- NaOH VS, Sodium thiosulphate VS

There are four pairs of electrons around the central carbon atom of methane. These pairs each consist of one electron originally from the carbon and one from the hydrogen atom bonded to it.
Though the question only considers the outer shell of electrons, as that is the only shell used for bonding, it may be useful to remember that in methane the carbon atom has a total of ten electrons around it, due to its two inner electrons.

Greenhouse gases are caused by pollution such as car fumes, power plants and even animals. the worst greenhouse gas is carbon dioxide or CO2 which lasts for about 100 years in the atmosphere. Also there is methane. Methane is more powerful than CO2 but lasts only for 10 to 15 years.
They are harmful to the environment as they heat up our planet. They stop the suns rays getting back into space once they bounce back from the earth.
From highest to lowest mass of carbon dioxide emitted:
# The Oceans
# Insects
# Humans
