# Consider the unbalanced equation... Ag(s) + H2S(g) + O2(g) Ag2S(s) + H2O(l)?

What is the maximum mass of Ag2S that can be formed when 0.600 g of Ag, 0.190 g H2S and 0.395 g O2 react?

4 Ag(s) + 2 H2S(g) + O2(g) ==> 2 Ag2S(s) + 2 H2O(l)

0.600 g Ag / 107.87 g/mole Ag = 0.00556225 moles Ag

0.190 g H2S / 34.09 g/mole H2S = 0.005573481 moles H2S

0.395 g O2 / 32.00 g/mole O2 = 0.01234375 moles O2

Limiting Reagent Time

------------------------------------

0.00556225 moles Ag x 2/4 molar ratio = 0.002781125 moles Ag2S produced

0.005573481 moles H2S x 2/2 molar ratio = 0.005573481 moles Ag2S produced

0.01234375 moles O2 x 2/1 molar ratio = 0.0246875 moles Ag2S produced

Ag is the limiting reagent

0.00556225 moles Ag x molar ratio of 2 moles Ag2S/4 moles Ag = 0.002781125 moles Ag2S

0.002781125 moles Ag2S x molar mass of Ag2S (247.81 g/mole) = 0.689190586 g of Ag2S

0.689 g Ag2S produced rounded to 3 significant figures

there isn't any Christian perception that announces she is going to hell if she would not "supply her existence to the Lord". of route she will be in a position to no longer. What a stupid and vicious component to assert. Please do no longer confuse Christianity with that "born again" nonsense. "Born again christians" are individuals of a cult, very such as Jehova's witnesses. they could say all non "born agains", Jews, Muslims, Hindus, Buddhists and pagans will bypass to hell. nicely, I do desire they have bunk beds and tents, because it will be sooo crowded. i'm effective that there isn't any punishment in the event you commit suicide, yet on the different hand, her existence isn't meant to end yet. there are any such remarkable style of ideal issues she ought to nevertheless get excitement from and somewhat of scaring her, i imagine you may make her see the sturdy issues. i understand this is confusing regardless of the reality that. yet at times it facilitates to communicate, or possibly bypass to a treatment once a week or so. do not ignore, suicide is an enduring answer to a momentary concern, because the Samaritans ought to assert.
