Answer:
Alpha particles, Beta particles, gamma rays, and neutrons
Explanation:
usually there's 2 ways radioactivity occurs: radioactive decay and ionization. radioactive decay breaks down the nucleas over time transforming the protons and neutrons into smaller particles alpha and beta with a little gamma radiation (gamma radiation is what was decaying). ionization is when the nucleas ejects neutrons as it's form of decay, leaving radioactive isotopes.
Answer:
The pond has more energy because I is so much larger that the Cup of boiling water. Since that mass of the pond is so much larger, It is generating more energy than a boiling cup of water.
The theory assumes that particles don't experience intermolecular forces. Thats right answer
I think the correct answer from the choices listed above is option D. the substances cobalt and barium chloride will not react since cobalt os less active than barium so it does not have enough energy to displace barium in the compound. Hope this answers the question.
