Copper (II) oxide reacts with hydrogen according to the equation. CuO(s) + H2(g) = Cu(s) + H2O(l)The mass, in grams, of copper formed when 8.0g of the oxide is reacted with excess hydrogen is (Cu=63.5; H=1; O=16) a.40640
b.635
c.10.08
d.6.39

Write the symbol for every chemical element that has atomic number greater than 3 and atomic mass less than 12.0 u.

Based on the equation and the information in the table, what is the enthalpy of the reaction?

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.
