Answer:
Nuclear fusion plays an important role in making elements that are heavier than helium.
Explanation:
Nucleosynthesis is the process by which new atomic nuclei are created from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis.
In order to synthesize a new element, there must be a change in the number of protons. We should remember that elements are known by the number of their protons as it represents their atomic number.
Elements heavier than helium are formed by nuclear nucleosynthesis in which nuclear fusion plays a very crucial role as typified by the equations shown in the question.
Spring a has more potential energy then spring b
A Geiger counter is a type of particle detector that measures ionizing radiation. Geiger counters are used to detect ionizing radiation
I believe the correct answer from the choices listed above is option C. The ratio of Al3+ ions to S2- ions in a neutral compound would be 2:3. When it is a neutral compound the chemical formula would be Al2S3. As you can see in every 2 ions of Al you need 3 ions of S to maintain neutrality. Hope this answers the question.
