Interpretation:
“Technique of radiocarbon dating band how it corrected for the changes in atmospheric concentrations of C-14 and ages” should be identified.
Concept introduction:
Method for measuring the age of organic remains which depends on the decay rate of carbon 14 is said to be Radiocarbon dating. Carbon 14 is the radioactive isotope of carbon having 6 protons and 8 neutrons in the atomic nucleus. The radioactive C-14 nuclide can be represented as 6C14. The age of any specimen with organic content like fossil, plants, dead bodies, etc. can be determined by radiocarbon dating.
Radiocarbon dating is a technique for calculating the age of organic matter that left is depends on the rate of decay of carbon 14. Carbon 14 is the radioactive isotope of carbon having 6 protons and 8 neutrons in the atomic nucleus. The radioactive C-14 nuclide can be represented as 6C14. The age of any specimen with organic content like fossil, plants, dead bodies, etc. can be determined by radiocarbon dating.

- While noble gas exerts the strongest London (dispersion) forces on neighboring atoms? Group of answer choices Xe Ar Kr Nearrow_forwardWhich of the following elements is corrosive to your skin due to that element breaking down C=C bonds? Group of answer choices fluorine iodine bromine chlorinearrow_forwardWhat the best source of sulfide to use on a small scale in the lab? Group of answer choices thiourea H2S NaHS Na2Sarrow_forward
- Which of the following statements about sulfur is FALSE? Group of answer choices H2S is the product of an oxygen-depleted ecosystem. In the acid mine drainage reaction, FeS2 is a product. One allotrope of sulfur has the formula S20. In the environment, bacterial oxidation can convert S2− to elemental S or SO42−.arrow_forwardOf the following choices, which is the best reason that most materials DON'T spontaneously combust even though our atmosphere is about 21% oxygen? Group of answer choices The reduction of O2 in the gas phase (O2 + e− → O2−) is spontaneous. The reduction of O2 in acid solution (O2 + H+ + e− → HO2(aq)) is spontaneous. O2 is not a reactant in combustion. The O2 bond dissociation energy is 494 kJ/mol, leading to a high activation energy for combustion.arrow_forwardplease answer in the scope of the SCH4U course, I am having a hard time understanding, may you show all steps please and thank you! can you also put the final answers in the table so its understandablearrow_forward
- Plan the synthesis of the following compound using the starting material provided and any other reagents needed as long as carbon based reagents have 3 carbons or less. Either the retrosynthesis or the forward synthesis (mechanisms are not required but will be graded if provided) will be accepted if all necessary reagents and intermediates are shown (solvents and temperature requirements are not needed unless specifically involved in the reaction, i.e. DMSO in the Swem oxidation or heat in the KMnO4 oxidation). There may be more than one correct answer, and chemically correct steps will be accepted. Extra points will be given if correct names are provided. The points earned here will be applied to your lowest exam score! H Harrow_forwardDraw the mechanism to make the alcohol 1-hexanol.
