For this question you need to find out all of the stages of a star and the process of a nuclear fusion. Then compare what's different about it and what's the same.

Answer:

False

Explanation:

A <em>main sequence star</em> is a star that fuses hydrogen into helium.

A massive star needs a higher pressure and temperature at its core to keep itself from collapsing.

It must burn up its core supply of hydrogen <em>more rapidly</em> than a less massive star.

As a result, it spends less time in the main sequence before it becomes a red giant.

<h3>Organometallic reagent</h3>

Organometallic chemistry is the study of organometallic compounds, which are substances that contain at least one chemical bond between a carbon atom from an organic molecule and a metal. These substances include alkali, alkaline earth, and transition metals, as well as metalloids like boron, silicon, and selenium. In addition to links to organyl fragments or molecules, bonds to 'inorganic' carbon, such as those to carbon monoxide (metal carbonyls), cyanide, or carbide, are also typically regarded as organometallic. Although they are not strictly speaking organometallic compounds, some similar compounds, such as transition metal hydrides and metal phosphine complexes, are frequently included in discussions of such substances. The phrase "metalorganic compound," which is comparable but different, describes molecules that contain metals but do not have direct metal-carbon bonds but do have organic ligands.
