Atomic halogens greatly speed the rate of ozone destruction through several steps in which they themselves are consumed and then regenerated. Rearrange the following chemical equations as needed and then combine them to show how Br atoms react with ozone to form oxygen but are not consumed in the overall process. Neither the Br atom nor the BrO radical should appear in the final chemical equation Reaction (a) Br(g) +O_3(g) rightarrow BrO (g) O_2 (g)
Reaction (b): Br(g)+2O_2(g) rightarrow BrO (g) O_3(g)

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
