Suppose you provided water with radioactive oxygen atoms to a plant. Into which kind of molecule would the radioactivity go?

Radioactivity is a phenomenon of the spontaneous emission of: A. protons (alpha particles) B. electrons (beta particles) C. gamma rays (short wave electromagnetic waves) D. All of the above

The label on a candy bar says that it contains 150 Calories. If you could convert all of that energy to heat, you could raise the temperature of how much water by 15°C?

Part A: In this diagram, a molecule of water is________. Part B: This is an example of _______. Part A Answer Choices: A. Required to split a larger molecule apart B. Created by joining two molecules together Part B Answer Choices: A. Hydrolysis B. Condensation

Explain how the type of decay, the half life and the chemical properties make the following radionuclides suitable for the given applications:  A single gram of polonium will reach a temperature of 500°C making it useful as a source of heat for space equipment (α emitter, half lives of polonium isotopes range from less than a second to 200 years).

It is simple to grind up a plant and then extract and measure all of the chemical elements present, but this does not tell us which elements are essential. Why not?

Which of the following forms of electromagnetic radiation has the highest energy?   Radio waves   Visible light   Microwaves   Infrared radiation

Ionizing radiation like removes from atoms.a. UV, protons b. X-rays, the charge c. gamma rays, electrons d. cathode rays, ions

“Navy coffee” is where the coffee is brewed strong and a bit of salt is added. What is special about water that allows you to put sugar or salt in your coffee? To help answer this question, consider the opposite situation: Why do salt scrubs that you buy in a high-end spa consist of large salt crystals in oil?

They counted the number of spatuals of sugar or salt added to the water until no more would dissolve. Why was not an accruate method of measuring how much sugar or salt they added?
