Why is the death of a Star important for our life on Earth?

Explanation:

No matter how a star dies, its life cycle can transform the universe. Without stars, the universe would contain nothing but clouds of hydrogen and helium. It is the life and death of stars that are responsible for the elements that make up everything you see on Earth!

What was the point of the Death Star?

No matter how a star dies, its life cycle can transform the universe. Without stars, the universe would contain nothing but clouds of hydrogen and helium. It is the life and death of stars that are responsible for the elements that make up everything you see on Earth!

Explanation:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
