10. Un volumen de 1.0 mL de agua de mar contiene casi 4.0 3 10212 g de Au. El volumen total de agua en los océanos es de 1.5 X 1021 L. Calcule la cantidad total de Au (en gramos) existente en el agua de mar y su valor total en dólares (Suponga que el oro tiene un precio de 948 dólares por onza)

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

i'm assuming that the correct answer is indeed the first one/ "a"..

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
