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.

Nickel (II) oxide reacts with carbon monoxide to form nickel metal. CO(g) + NiO(s) ⇄ CO2(g) + Ni(s) Kp = 20 at 873 K If a reacti

Answer:

Explanation:

Hello,

Based on the statement of the equilibrium law:

$Kp=\frac{P_{CO_2}^{EQ}}{P_{CO}^{EQ}}$

By increasing (doubling) the amount of carbon monoxide, the production of nickel will increase since its amount is directly proportional with its pressure, so, by adding more reactant (in this case carbon monoxide), the equilibrium is rightward shifted based on Le Châtelier's principle even when solid either reactants or products are not contemplated in the equilibrium law.

Best regards.
