URGENT HELP PLEASE When exposed to UV light,
chlorine and hydrogen gases
explosively combine to form
hydrogen chloride gas. Assuming
a sufficiently strong reaction
vessel how much HCl (in atm) can
be formed when hydrogen and
chlorine are each at 8.6 atm
(assume volume and temperature
are constant)?

Explanation:

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

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
