In the following reaction, if there were 10 molecules of nitrogen gas (N2), how many molecules of hydrogen gas (H2) and ammonia gas (NH3) would be present
in the reaction?
N2 + 3H2
+
-> 2NH3
N2 = 10; H2 = 30; NH3 = 20
N2 = 10; H2 = 30; NH3 = 10
N2 = 10; H2 = 800; NH3 = 700
N2 = 10; H2 = 60; NH3 = 20

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.

One way that radioactive waste is treated is by burying it in repositories. the repositories are found only in states with very low populations. true or false? a. trueb. false(also i meant to put high school but it put down middle school instead)

Which answer tells the reason the earth’s climate is getting warmer? too many animals are becoming extinct. large glaciers are melting in antarctica. the earth is moving closer to the sun. driving cars gives off gases that trap heat in the atmosphere.
