Fusion reactions constitute the fundamental energy source of stars, including the sun. hydrogen “burning” initiates the fusion energy source of stars and leads to the formation of helium. generation of fusion energy for practical use also relies on fusion reactions between the lightest elements that burn to form helium. in fact, the heavy isotopes of hydrogen—deuterium and tritium—react more efficiently with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei. the hydrogen nucleus consists of a single proton. the deuterium nucleus has one proton and one neutron, while tritium has one proton and two neutrons. what conclusion can be drawn from this information? a) deuterium and tritium are required to burn hydrogen. b) the most efficient fusion reactors would use two hydrogen nuclei. c) the most efficient fusion reactors would use heavier forms of hydrogen. d) helium occurs naturally. the burning of hydrogen is not required to get helium in nature.

C)  The most efficient fusion reactors would use heavier forms of hydrogen.

Explanation:

From the information presented to us in the question, the third sentence reveals that heavier forms of hydrogen produces larger amount of energy and most importantly reacts more efficiently when fusion occurs.

In fact, the heavy isotopes of hydrogen—deuterium and tritium—react more efficiently with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
