scientists recently found a way to make inexpensive hydrogen that can be used as a fuel. this process of hydrogen production has some similarities with photosynthesis.\nin plants, photosynthesis uses energy from the sun to chemically combine water and carbon dioxide into sugar and oxygen gas. the sugar is then used as a fuel source for the plant and organisms that consume the plant.\nto produce hydrogen, scientists mixed extremely small particles of cadmium and selenium, which emit electrons when exposed to light, and ascorbic acid, a chemical that produces hydrogen ions when it decomposes. the scientists used a nickel catalyst, which causes the emitted electrons to combine with the hydrogen ions and form hydrogen gas. this reaction is continuous, and after two weeks, the hydrogen gas was still being produced. the scientists hope this will be a viable fuel source in the future.\nwhich comparison of this new process of hydrogen production and photosynthesis is supported by the information provided?\na. the new process is more efficient than photosynthesis.\nb. both processes change light energy to chemical energy.\nc. both processes result in the production of hydrogen gas.\nd. the new process emits more electrons than photosynthesis.

Answer

Brief Explanations:

  1. Analyze option A: There is no information comparing the efficiency of the new process and photosynthesis in the text, so A is incorrect.
  2. Analyze option B: In photosynthesis, light energy is used to chemically combine water and carbon - dioxide. In the new hydrogen - production process, small particles of cadmium and selenium emit electrons when exposed to light, which is also a conversion of light energy to chemical energy. This option is supported by the text.
  3. Analyze option C: Photosynthesis produces sugar and oxygen gas, not hydrogen gas, so C is incorrect.
  4. Analyze option D: There is no comparison of the number of emitted electrons between the new process and photosynthesis in the text, so D is incorrect.

Answer:

B. Both processes change light energy to chemical energy.
