I'm stuck and am hoping you can help. Here is the problem: You react 7.92 grams of silver nitrate, AgNO3(aq), with an excess of sodium chloride, NaCl(aq). How many grams of silver chloride, AgCl(s), will precipitate from the solution? Any help would be appreciated. Most of ...

"Why must a chemical reaction be balanced before it can be used in stoichiometry?" I mean, I get it, that the equation will be off if it doesn't start out balanced, but, why? How do I phrase that?

Stoichiometry is based on the realtionship between the mols of one material that reacts with (or produces) another. If the equation isn't balanced, the mole ratios don't reflect the true relationship and that leads to erroneous calculations and conclusions.

You're half way there IF the H2S is at STP. If not then an adjustment needs to be made. But let me start over to make sure we don't miss something. Here are the general steps (assuming STP conditions for the H2S). Step 1. Write the balanced equation. You have done that. 2HCl...

There is a long way and a short way. The long way uses conventional stoichiometry. The short way says that for an all gaseous reaction, we can omit changing everything to mols, making conversions, and changing back to liters. We can just operate in liters. Therefore, 1 liter ...

Very simple. You just run the usual stoichiometry twice. First you have 1.8 moles K. moles KCl produced = 1.8 moles K x (2 moles KCl/2 moles K) = 1.8 moles KCl Then you have 1 mole Cl2. moles KCl produced = 1 mole Cl2 x (2 moles KCl/1 mole Cl2) = 2 moles KCl. Obviously both ...
