Carbon-14 has a half-life of 5
WebJul 2, 2014 · Jul 3, 2014. Half-life (t½) is the amount of time required for a quantity to fall to half its value as measured at the beginning of the time period. In this question (t½) of C-14 is 5730 years, which means that … WebCarbon-14 then moves up the various food chains to enter animal tissue—again, in about the same ratio carbon-14 has with carbon-12 in the atmosphere. When a living thing dies, its radiocarbon loss (decay) is no longer balanced by intake, so its radiocarbon steadily decreases with a half-life of 5,730 years.

WebAug 7, 2016 · Half-life of carbon-14 = 5720 years First we have to calculate the rate constant, we use the formula : Now we have to calculate the age of the sample: Expression for rate law for first order kinetics is given by: where, k = rate constant = t = age of sample = ? a = let initial amount of the reactant = 100 g x = amount decayed = 75 g WebIt is possible to determine the probability that a single atomic nucleus will "survive" during a given interval. This probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and ...
