Answer:
Una cadena alimentaria es una secuencia lineal de organismos a través de la cual los nutrientes y la energía pasan de un organismo a otro mediante consumo. ... Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas
Explanation:
A food chain is a linear sequence of organisms through which nutrients and energy pass from one organism to another by consumption. ... Food webs consist of several interconnected food chains and are a more realistic representation of consumption relationships in ecosystems
I believe the end result is still 83 moles since there is never an amount of sulfur atoms added to the initial amount, but rather oxygen and water is repeatedly added to it. To find it's weight, first find the molar mass of H2SO4:
H2 + S + O4 = 2.00 + 32.1 + 64.0 = 98.1 g/mol
and mass = (98.1 g/mol)(83 mol) = 8142.3 g
rounded to 8.1 x 10^3 g assuming 100% yield?
