How many liters of C12 gas at 200°C and 0.75
atm can be produced by
the reaction of 12.0 g of
MnO2 (MM= 87 g/mol)
with HCl as follows?
MnO2(s) + 4HCI(aq)
MnCl2(aq) + 2H20(1) +
Cl2(g)​

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

your answer would be “dry”
