Mole Ratio Worksheet All the following chemical reactions are balanced, please write your mole ratios like this 1:2, and ½ both ways. This is important in the future. Here’s a video in case you need help, or missed the lecture notes, lecture, and practice problems. https://www.youtube.com/watch?v=c9beXPzJ-Fs Step 1) RTFQ- read the funny question, circle the known (what I know), and what you need (what I want to know). Step 2) Set up DA, your KNOWN in the top left box, then cancel the units till you get the unit you want. Step 3) Do the math= calculate __Zn + 2HCl __ZnCl2 + __H2 balanced equation. a.
