We calculate for the number of moles of water given its mass by dividing the given mass by the molar mass. 
                               n water = (36.04 g) / (18 g/mol) 
                                n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
                                n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
                                n oxygen  = 2.33 mols O2

CICLOS BIOGEOQUIMICOS: lugares en que encontramos el elemento del ciclo separando en bioticos y abioticos
scoundrel [369]

Answer:

Los ciclos biogeoquímicos son definidos como la circulación de los elementos químicos entre organismos biológicos (es decir, el factor biótico del ciclo), y componentes geológicos inorgánicos del sistema (factores abióticos). En el ciclo del agua, por ejemplo, este elemento se encuentra esparcido en los ríos y arroyos, como así también en la atmósfera, desde donde fluye como lluvia hasta el suelo y puede ser ingerida por organismos vivos terrestres y es utilizada para llevar a cabo diversas funciones celulares.

Explanation:  

Los ciclos biogeoquímicos establecen un vinculo entre los factores bióticos y abióticos del ecosistema, de modo que la energía puede fluir libremente a través de ambas partes del sistema. Los seres vivos necesitan diferentes elementos químicos para sobrevivir, los cuales forma parte de los ciclos biogeoquímicos. En los ciclos biogeoquímicos los elementos se conocen como 'nutrientes' (micro y macronutrientes). Estos elementos se encuentran esparcidos tanto en la corteza de la tierra como en la biósfera. Los nutrientes son indispensables porque de ellos depende de que la energía fluya entre el componente inorgánico y orgánico del ciclo. Por otra parte, los nutrientes también circulan dentro del ciclo entre componentes bióticos de la cadena trófica, con lo cual no sólo los nutrientes sino también la energía fluye entre organismos, desde aquellos más basales en el sistema tales como plantas (ecosistemas terrestres) o algas (marinos), hasta los niveles superiores representados por especies animales hervívoras y carnívoras de tales ecosistemas.

If 200 grams of hydrogen gas react with 150 grams of oxygen gas, then how many grams of water will be produced
Allushta [10]
2H2 + O2 -> 2H20 is the balanced equation for the reaction of Hydrogen with Oxygen to form water so If you have 32g of O2 this is a simple Dimensional analysis problem 32g O2 x 36.03056g H20/31.9988g O2 this way the O2 cancels out and you are left with just the H2O so your raw answer would be 36.0319112, then if your instructor requires a significant figure answer that would be to 2 significant figures the information you were given 32g O2, so as above 36g or Water are produced. Just a different way to view and solve the problem with the balanced equation so you can see the way everything relates to everything else. the molar masses of O2 and H2O are simply found my adding up 2 Oxygens 15.9994g x2 = 31.9988g and H2O = 2(1.00794) + 15.9994 = 18.01258 but you then have to multiply that by 2 because the reaction states you get 2 mols in the reaction so that is where I came up with the 36.03056g for the solution. Hope this helps. Dimensional Analysis is and can be one of the best ways to solve these problems, because not always are you going to be dealing with 1:2 ratios.
