why were you unable to use non-integer numbers (like ½ or 0.43) for the coefficients in a balanced chemical equation?

For the reaction of sodium sulfide with iron(III) chloride below (as an unbalanced reaction - that's how I will almost always give you reactions.  ALWAYS check to see if a reaction is balanced before you use it.  You balanced it in the last question; make sure you have that right before you start calculating!), you have 319.5 kg of sodium sulfide and 502.3 kg of iron(III) chloride available. What mass (in kilograms) of sodium sulfide do you NEED if you're going to reduce  all of the iron(III) chloride you have?   Na2S(s)  +   FeCl3(s)    →   Fe2S3(s)   +  NaCl(s)

Define/describe stoichiometry and it’s purpose?

[Review Topics] [References] "Smelling salts," which are used to revive someone who has fainted, typically contain ammonium carbonate, (NH4)2CO3. Ammonium carbonate decomposes readily to form ammonia, carbon dioxide, and water. The strong odor of the ammonia usually restores consciousness in the person who has fainted. The unbalanced equation is (NH4)2CO3 (8)→ NH3(g) + CO₂(g) + H₂O(g) Calculate the mass of ammonia gas that is produced if 0.850 g of ammonium carbonate decomposes completely. g NH3 Submit Answer Mastered Retry Entire Group 8 more group attempts remaining Previous Next Save and Exit

ou are asked to weigh 2 g of lithium and add it to 1500 ml of distilled water +2drops of indicator, knowing that the density of water is 1 at room temperaturewhile conducting this experiment. What type of reaction occurs? Write and balance the equation of this reaction. Is there a gas that will be emitted? How can you test that this gas was released
