In a constant‑pressure calorimeter, 70.0 mL of 0.320 M Ba(OH)2
was added to 70.0 mL
of 0.640 M HCl.

The reaction caused the temperature of the solution to rise from 23.56 ∘C
to 27.92 ∘C.
If the solution has the same density and specific heat as water ( 1.00 g/mL
and 4.184J/g⋅°C,)
respectively), what is Δ
for this reaction (per mole H2O
produced)? Assume that the total volume is the sum of the individual volumes.

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.
