Here are the answers to your questions:

Question 19
A nucleus decays to produce a nucleus with one additional proton. Which type of decay did the nucleus undergo?
Response: beta-plus decay
Explanation: In beta-plus decay, a proton is transformed into a neutron, emitting a positron, which results in an increase in the proton number.

Question 20
Which type of decay is a form of nuclear fission?
Response: None of the provided options are correct.
Explanation: Nuclear fission specifically refers to the splitting of a heavy nucleus (like uranium) into lighter nuclei, usually accompanied by the release of energy. It is not classified under alpha decay, beta decay, or gamma decay.

Question 21
A nuclear power plant is a thermal power station which generates ______ from heat.
Response: electrical energy
Explanation: Nuclear power plants convert the heat generated from nuclear fission into electrical energy.

Question 22
Which of these DOES happen in a nuclear fission reaction?

  • Uranium atoms are split. True
  • A chain reaction occurs. True
  • Light nuclei come together to form a single heavier nucleus. False
  • A large amount of heat is given off. True
    Explanation: In nuclear fission, heavy atoms (like Uranium) split into lighter atoms, releasing a significant amount of heat and initiating a chain reaction.

Question 23
Have you completed or scheduled a CBA phone call with your chemistry teacher?
Response: I have not completed the call BUT I scheduled a call with my teacher this week.
Explanation: This response indicates that you are aware of the requirement and have taken steps to schedule the call.
