In a famous experiment, wöhler heated ‘inorganic’ ammonium cyanate in the absence of air. the only product of the reaction was ‘organic’ urea, co(nh2)2. no other products were formed in the reaction. what is the formula of the cyanate ion present in ammonium cyanate? a cno– b cno2– c co– d no– why a?

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.
