Explique en palabras la reacción química de la formación del dióxido de carbono (CO2)
Respuestas a la pregunta
Respuesta:
Carbon dioxide is a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% by volume, having risen from pre-industrial levels of 280 ppm. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth. However, at normally encountered concentrations it is odorless.
El dióxido de carbono, el gas carbónico o el anhídrido carbónico es una molécula compuesta por un átomo de carbono (C) y dos de oxígeno (O). La reacción química de formación del CO2 es simple y ocurre de la siguiente manera: C + O2 ⇒ CO2
