What is the daughter product of the nuclear decay equation of C14?
N14
What is phenolphthalein made of?
Phenolphthalein is made up of, H20, C14, O4,
List a range of items that can be dated by isotope carbon 14?
It is not that simple. Carbon 14 (C14) is created in the upper atmosphere by the action of cosmic rays on Nitrogen atoms. There is not much of it, C14 occurs in trace amounts, only making up as much as 1 part per trillion (0.0000000001%) of the carbon on the Earth. This amount of C14 is in balance, the amount created in the upper atmosphere balances the amount lost by the natural radioactive decay of the isotope. All living things on earth, are made of chemicals that include carbon and, while living, the amount of C14 in them is in balance with the amount of C14 in the atmosphere. However when a living thing dies it no longer mixes the carbon in its body with that of the atmosphere and thus the amount of C14 it contains begins to reduce to levels below that found in the atmosphere because the C14 decays radioactively. Thus items to be dated using C14 must contain carbon (wood, charcoal, hair and bones are good) and must have remained undisturbed since the organisms death. Also C14 decays rather quickly and is therefore only good for dating items that are less than about 60,000 years old.
What isotope serves as the current standard for the atomic mass scale?
with C14 atom
What is the molecular mass of myristic acid C14 H28 O2?
228.37092g/mol
What is the difference between c 12 and c 14?
C12 and C14 are isotopes of the Element Carbon. C12 is the most abundant of all which is 99% of all the Carbon on earth while C14 is only 0.0000000001% (trace amount). C12 has a Atomic Number of 12. It has 6 Protons and 6 Neutrons. C14 has a Atomic Number of 14. It has 6 Protons and 8 Neutrons. C14 is radioactive in nature. It is used for carbon dating.
What are the release dates for C14 - 2013?
C14 - 2013 was released on: USA: 30 October 2013 (limited)
Is carbon dating is a type of technology currently used to study the past?
Yes, measurements of the ratio of carbon-14 (radioactive) to carbon-12 (nonradioactive) in a sample is used as a type of clock to determine the age of the sample. BTW, ever wonder why C14 dating works? Presumably, the organism is eating a constant proportion of C14 while it lives. So when it dies, the C14 is not being replenished. Sounds awful fishy to me, but what else is there? I would have like the process better if the organism were making C14 at a constant rate-- but alas, not so.
Explain the ''cup'' analogy used in the puzzle?
The c14 is significant to the survival of the aging never ending rats
What is the c-14 c-12 ratio used to date once living organisms?
It is because living organisms absorb C14 from their environment. After death, they are no longer capable of absorbing any more C14. So, at the time of death, the C14 : C12 ratio is fixed. C14 undergoes radioactive decay (into C12) so the C14 : C12 ratio declines and that can be used as a measure of the time since death.
What formulas will give you the total value of a series of numbers displayed in column C from C1 to C14?
The simplest and best way is: =SUM(C1:C14)
Is sodium C14-16 olefin sulfonate a sulphate?
No. it is sulfate free but I hear it can be irritating and drying as SLS but i have used it with no drying and irritation.
C14 bouble barrel shot gun?
Yes.
What is the chemical formula of lidocaine?
C14 h22 n2o
The half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
There would be 1/32 left.
What half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
1/32 of the original amount.
Why can carbon-14 be used to date a 40000 year old tree but U-Pb cannot?
C14 is continuously made in the atmosphere by the effects of solar radiation on Nitrogen14. There is an equilibrium up there between how quickly C14 is made and how quickly it decays to C12 because the gases circulate. Obviously this circulation stops when a C14 molecule gets incorporated into a plant or something that ate the plant. Over time the C14 in a tree disappears while C14 in the iar keeps gettin renewed. Our dating technique relies on the difference between how much C14 is left in the tree compared to what can be found in the air. I dont think the same can be said of U. It and other heavy elements are not airborne and were in any case made in a dying sun. Therefore the ratio of Pu, U, Pb and other heavy elements is the same whether in a tree or in the soil that the tree grew up in. So while any U that found its way into the tree will have decayed, the U in the soil will have decayed too. Therefore our C14 (which relies on measuring differences) cannot be used. Full disclosure: I have MSc Molecular Biology but I am NOT an expert in carbon dating. Double check before you rely on this information as gospel.
