When you go into the chemistry lab, you measure out reactants and products in grams with a balance. Why do we have to keep converting between grams and moles? The answer is extremely practical. To use conversion factors, remember to set up the factor so that the units in the bottom of the factor cancel with the units you currently have.Worksheets are factor label work factor label work unit conversion using the factor label method objective factor label method work activity unit conversion key factoring trinomials a 1 date period. Remember to use unit equalities as conversion fractions to cancel out variables until ending with the desired new variables.

For example, you say, 'I drove 40 miles per hour.' Normally, you don't say, 'I drove 120 miles per 3 hours.' Figure out how to convert a rate like 120 miles per 3 hours to the unit rate of 40 miles per hour by watching this tutorial. When you talk about the speed of a car, you usually say something in miles per hour.Introduce and reinforce math topics with videos, slideshows, step-by-step tutorials, and other activities.Sept 25/26th: Graphing lab: here: Sept 30. click on the following answer sheets: Worksheet 2 Worksheet 3 Worksheet 4 a Worksheet 4b. Therefore, you should write the electron configuration for 18 electrons. So although a neutral atom of sulfur has 16 electrons, the ion of sulfur, S 2-, has gained two electrons. Answer: Al 3+: 1s 2 2s 2 2p 6 Given : S 2-Sulfur will gain two electrons when it forms an ion.
