Astudent burns 1.50 mol c3h8 according to the following reaction:
c3h8 + 5o2 3co2 + 4h2o.
how many grams of carbon dioxide are produced?

1.50 mol C3H8 X (3 mol CO2 / 1 mol C3H8) X (44.0 g CO2 / 1 mol CO2) = 198 g CO2

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.

have a great day because if you dont you and i will be sad
