- is made mostly of hydrogen and helium  

-will eventually run out of fuel and die  

-creates energy through nuclear reactions

Explanation:    

The sun an average mass and sized star composed of hydrogen and helium gas. It generates energy in its core by nuclear fusion reaction. It is the only star in the solar system. Once all the fuel is run out, the nuclear fusion reaction would stop and the sun would die. There are billions of stars in our milky way galaxy and sun is not the largest of them.

How many carbon atoms are there in 5 molecules of CHCl3?
lukranit [14]

There are 5 carbon atoms present in the Chemical formula, CHCl_\\{3} .

<h3>What is a chemical formula?</h3>

A chemical formula is used to show the number and type of atoms present in a molecule, using the atomic symbols of the elements and numerical subscripts.

From the chemical formula;

We can deduce that we have the following elements and their corresponding number of atoms in one molecule of the compound;

Carbon = 1 atom

Hydrogen = 1 atom

Chlorine = 3 atoms

So, in 5 molecules of the compound;

Carbon = 1 x 5 = 5 atoms

Hydrogen = 1 x 5 = atoms

Chlorine = 3 x 5 atoms = 15 atoms

In conclusion, from the solution above, we can say that we have 5 atoms of carbon present in 5 molecules of CHCl_3.

If gas in a sealed container has a pressure of 50 kPa at 300 K, what will the pressure be if the temperature rises to 360 K?
Tresset [83]
Since gas is sealed in container, volume of gas will ramain constant. from ideal gas equation PV=nRT, P/T = nR/V ==> P/T = constant.( constant since v is constant so whole term must be constant). therefore, (P/T)1 = (P/T)2.==> 50/300 = P2/360. ==> P2= 50X360/300 = 60KPa. Hope this helps
