I. The Importance of Balanced Reactions
• We have been balancing chemical reactions so that we can use them in these calculations.
• Without a balanced reaction, we CANNOT do the calculations that we use in stoichiometry.
![Page 10: Catalyst What are the components that affect the rate at which something dissolves? If I increase the temperature will a solute dissolve more slowly or](https://reader035.vdocuments.us/reader035/viewer/2022062805/5697bfdb1a28abf838cb05ce/html5/thumbnails/10.jpg)
II. Mole Ratios• The coefficients in a balanced equation
represent the moles of each substance.• These coefficients can be used as a conversion
factor known as a mole ratio• Mole ratios allow for us to convert between
moles of two substances
