Anew element -- quickly named reachium by the scientific community -- is discovered. this element is found to have
two isotopes. 86.4% of all reachium atoms are reachium-328 and 13.6% are reachium-333. what is the atomic mass of
this element?

Y=‐1x + 7 if y has a value of ‐24 what is the value of x?

Can you me with this i really appreciate it

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
