How many moles of oxygen are produced if 15 grams of iron (iii) oxide decomposes completely

 Stoichiometry is a big word for a process that chemist’s use to calculate amounts in reactions. It makes use of the coefficient ratio set up by balanced reaction equations to make connections between the reactants and products in reactions.

 Stoichiometry calculates the quantities of reactants and products in a chemical reaction. The equation must be balanced!

 Questions that deal with amounts in reactions are examples of reaction stoichiometry. We already have the tools necessary to solve this question. We just need to learn a new way to apply skills such as writing chemical formulas, calculating formula masses, and converting from mass to moles, particles to moles, and volume of gases to moles.

 Mole to Mole Conversions- you must have the Mole Ratio.

Explanation:

hope this helps you :)

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
