The half-life of carbon-14 is 5730 years. Dating organic material by looking for C-14 can't be accurately done after 50000years. Suppose a fossilized tree branch originally contained 4.30grams of C-14. How much C-14 would be left after 50000 years

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
