- Composition stoichiometry deals with the mass relationships of elements in compounds.
- Reactions stoichiometry involves the mass relationship between reactants and products in a chemical reaction.
Mole Ratios
- A mole ratio is a conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction.
a good way to get help on the homework tonight is to look at the activity series page in section three and HA kyle FIRST COMMENT
ReplyDeletean excellent introduction video to stoichiometry from khan academy:

another helpful tip for the homework. remember if two are being joined it is SYNTHESIS. one being broken into two it is DECOMPOSITION. other, SINGLE REPLACEMENT on the first section. also, look to the tables with charges to help you when you're balancing the equations.
ReplyDeleteGahhhh, Chris! Oh, well. The diagrams in the book explain and illustrate the process of going from moles to mass, mass to moles, and moles to moles very well. They helped me a lot on the homework. DON'T FORGET we have 2, I say 2, Homework assignments tonight, and both are due tomorrow. Bummer...
ReplyDeleteGood job on the blog, Klueser, short and sweet is great!

remember that the mole ratios are infinitely significant and as such you would look elsewhere to find out how many sig figs the answer needs
