Deposits of elemental sulfur are often seen near active volcanoes. their presence there may be due to the following reaction of so2 with h2s:

so2(g) + 2 h2s(g) â 3/8 s8(g) + 2 h2o(g)
assuming the values of îhâ°rxn and îsâ°rxn do not change appreciably with temperature, over what temperature range is the reaction spontaneous?

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.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
