Will give a team of researchers are working on a project to make a new kind of airplane fuel. during their experiment, there was an explosion that destroyed the lab. while they were cleaning up the debris, they discovered a number of pieces of frozen metal. the scientific community was amazed. the researchers were so excited to report that they had discovered a fuel that burns so hot that it becomes cold. they were not sure of the true importance of their discovery but they knew it was something that had never been seen before. the researchers quickly wrote up a report, created a press release, and applied for a patent. the news spread quickly through the world wide scientific community and soon other scientists were trying to replicate their experiment. much to the relief of the original team or researchers, no other scientist could ever replicate their find. would this example be considered science or pseudoscience? support your decision with at least three reasons

⤷ This is an example of pseudoscience. One, they would need to figure out what caused the explosion and what led to the frozen metal. Metal is naturally cold, and this needs to be truly proven. Second, it can’t be replicated by other scientists, making it hard to believe that there’s a gas that can make things so hot that it’s cold. Finally, the text says that they “quickly wrote up a report”, this sounds like they let their excitement get in their way, so they weren’t 100% clear with their “theory” (not discovery).

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
