Answer:
Esto significa que la masa en las moles de plomo es mayor que en las de plata.
Explanation:
Las moles de los átomos representan la cantidad de átomos presentes. Para saber la masa de los átomos debemos convertir las moles a gramos usando el peso molecular de cada uno de los átomos (207.2g/mol para el plomo y 107.82g/mol para la plata).
La masa de plomo en 300 moles es:
300 moles * (207.2g / mol) = 62160g de plomo
Y la masa de plata es:
300 moles * (107.82g / mol) = 32346g de plata
Esto significa que la masa en las moles de plomo es mayor que en las de platabased on the activity series, what are the predicted products of this reaction?

What is an ecosystem?An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
