Carbon is unreactive with a number of common lab substances: sulfuric acid, hydrochloric acid, chlorine, or any of the alkalis.It does burn in oxygen, and if you can pass the combusted gas through limewater, the carbon dioxide will turn the limewater milky by producing calcium carbonate.The core accreted gas quickly, preventing large amounts of material from slipping into the inner solar system — hence why Mercury, Venus, Earth, and Mars are all small planets and our solar system lacks large, rocky super-Earths.By the time the second nebular cloud formed, Jupiter was already 50 times as massive as modern-day Earth, according to the team's model."Our measurements show that the growth of Jupiter can be dated using the distinct genetic heritage and formation times of meteorites," Kruijer said. "Jupiter is the oldest planet of the solar system, and its solid core formed well before the solar nebula gas dissipated, consistent with the core accretion model for giant planet formation." Assuming that it's accurate, this dating will be a valuable tool in our understanding of how the early solar system formed.For instance, isotope analysis found that Jupiter's solid core formed with the first nebular cloud, only 1 million years after the start of the solar system.By studying other planets, we are learning more about our own planet.The effects of impacts and how they might affect us here on Earth, global climate change (Venus vs.
"We do not have any samples from Jupiter (in contrast to other bodies like the Earth, Mars, the moon and asteroids)," said study lead Thomas Kruijer.While not a chemical test, the presence of carbon in a sample (like a meteorite) can be found by vaporizing the sample and passing it through a mass spectrometer.This is also a way to get at the abundance of the various isotopes of carbon.This decay, or loss of energy, results in an atom (element) of one type, called the parent nuclide transforming to an atom of a different type (another element or another isotope of the same element), named the daughter nuclide.For example: a carbon-14 atom (the "parent") emits radiation and transforms to a nitrogen-14 atom (the "daughter").
