Provided here is a reversible reaction that is exothermic. Which of the following correctly describes the result of a change in temperature to this chemical system? N2 + 3H2 ⇔ 2NH3 + heat * A decrease in temperature would result in more nitrogen being produced.
An increase in temperature would result in less ammonia being produced.
A decrease in temperature would result in less ammonia being produced.
An increase in temperature would result in less hydrogen being produced

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.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
