1¿Cómo puedes clasificar el ciclo del carbono? 2¿Cuáles son los principales emisores de gas carbónico a la atmósfera y cuáles son los principales sumideros en el planeta? 3¿Cómo está representada la reserva de carbono en la atmósfera? 4). El fuego destruye reservas forestales liberando CO2, este pasa por acción del viento a la troposfera para engrosarla y hacer que se produzca el calentamiento global. Realice una gráfica explicativa de este fenómeno. 5¿En qué forma se encuentra el carbono en el agua dulce y océano? 6 Explique cómo en la fotosíntesis el carbono pasa a formar parte de los tejidos vegetales. 7 ¿Cómo se formaron los combustibles fósiles y porque contienen Carbono? 8¿Cómo nos hemos visto afectados en los últimos años por el calentamiento global? 9 Indique tres diferencias entre efecto invernadero y calentamiento global. 10 Recuerde siempre que cada minuto los seres humanos emitimos 48 mil toneladas de dióxido de carbono a la atmósfera. Y todos podemos ayudar a disminuir esta cantidad. Enuncie 5 acciones, que desde la cotidianidad contribuyan a la reducción de CO2

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
