PbCl2 and PbCl4
Empirical formula is when the molecular formula is reduced (each element) by the same number until you are unable to do so any further.
CH2O cannot be further reduced, but C3H6O3 can all be divided by 3 making it CH2O (same empirical formula)
The correct answer for this statement would be FALSE. It is considered false since exothermic reactions release energy, therefore, this energy can be considered more of a product, instead of the reactant. Hope this is the answer that you are looking for.
Since the scientists found a fossil from a modern day badger from the Holocene geologic epoch, the badger would be mostly the same, as this is the most recent, and still on going geologic epoch, starting from little less than 12,000 years ago. If the scientist wants to find a fossilized remains of earlier badgers, thus of their ancestors from the Pleistocene epoch, than the scientist should dig deeper. Not a lot deeper though, as the layers of rock from the Pleistocene are just bellow the layers of rock from the Holocene, as the Pleistocene is the second youngest geologic epoch, being the predecessor of the Holocene.
