Explain why it is important for Carbon to move through a Cycle and to never be depleted (gone forever) from any part of
the Earth. Give specific examples as to why Carbon is important
in at least of 3 spheres of the earth?

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
