Answer:
Pat is most likely to have made the hydrofluoric acid. My first piece of evidence is that the chemical supply company delivered sulfuric acid and calcium fluoride to Pat’s house However, these substances were not found at Pat’s house. This could mean that Pat used these substances in a chemical reaction. This evidence supports my claim because a chemical reaction between sulfuric acid and calcium fluoride could cause the atoms to rearrange to form hydrofluoric acid as one of the products. This is because sulfuric acid contains hydrogen atoms, and calcium fluoride contains fluorine atoms, which are the two types of atoms that repeat to make up hydrofluoric acid.
My next piece of evidence is that the police found calcium sulfate at Pat’s house. This evidence supports my claim because if Pat mixed the sulfuric acid and the calcium fluoride to make hydrofluoric acid, then the other product of this reaction could be calcium sulfate. This is because only the hydrogen and fluorine atoms would rearrange to form hydrofluoric acid. The rest of the atoms of the reactants would have to rearrange to form another substance. Calcium sulfate is probably the other product that would form because its atom group contains all the atoms that did not rearrange to form hydrofluoric acid. This evidence suggests that Pat mixed sulfuric acid and calcium fluoride to make the hydro.. whatever.
How do you think scientific discoveries regarding synthetic medicines like aspirin have impacted the pharmaceutical industry?
(thanks!)
Answer: The discoveries of synthetic medicine have gave the pharmaceutical industry more opportunities to more efficiently assist others. The synthetic medications are more effective and could be more cost efficient for the people taking them and the manufacturers and thus also gives the pharmaceutical industry more relevance in terms of the medical industry and the scientific world.

Which statement describes what is gained or lost during radioactive decay?
Atoms gain other atoms.
Elements take in energy.
Atoms lose smaller particles.
Elements gain smaller particles.
Answer: The correct statement is: Atoms lose smaller particles during radioactive decay.
Explanation:
Radioactive decay is a process where unstable atomic nuclei lose energy by emitting radiation in the form of particles or electromagnetic waves. As a result of this process, the unstable atoms transform into a different element or isotope. During the decay, the atoms lose smaller particles such as alpha particles, beta particles, or gamma rays. This loss of particles changes the number of protons and neutrons in the nucleus, which leads to the formation of a new element.
statement describes what is gained or lost during radioactive decay: atoms lose smaller particles. That is the third option, as during radioactive decay, the nucleus of an atom can lose subatomic particles, such as alpha or beta particles, which results in the transformation of the original atom into a new atom or a different isotope of the same element.
