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.

Which compound is used to make asphalt?
Masteriza [31]
Asphalt is a biproduct of making gasoline, diesel, kerosene, jet fuel, all from crude oil pumped from the ground. Asphalt is the garbage or waste that comes out the bottom of the process of distilling those products. They heat the thick oily-sooty gunky asphalt and mix it with rock or sand and make roads out of it. So the compound would be the long hydrocarbon chains.

A container of a mixture of 4 gases has a total pressure of 35.7 kPa. Gas A has a partial pressure of 7.8kPa. Gas B has a partia
Maurinko [17]

Answer:

partial pressure of gas D Pd = 15.5 kPa

Explanation:

As per the Dalton's law of partial pressure, in a mixture, pressure exerted by each gas when summed gives the total partial pressure exerted by mixture.

P(Total) = P1+P2+P3.....

Given P(Total) = 35.7 kPa

Partial pressure of gas A Pa = 7.8 kPa

Partial pressure of gas B Pb = 3.7 kPa

Partial pressure of gas C Pc =  8.7 kPa

There, Partial pressure of gas D Pd = P(Total) -(Pa+Pb+Pc)

Pd = 35.7-(7.8+3.7+8.7) = 35.7-20.2 kPa = 15.5 kPa

Therefore, partial pressure of gas D Pd = 15.5 kPa
