Introduction – Regents Chemistry
“The first day of class should connect to the last day and every day in between!”
This is a course in Regents Chemistry. The coursework includes the standards from the NYS Board of Regents, Physical setting, Chemistry and some concepts beyond the scope of the NYS standards
Ok so let’s get started on how this course is a bit different than Living environment.
The WHB Regents Living Environment passing rate was 93 %.
The WHB Regents Chemistry passing rate was 63 %.
Chemistry is also different in that not all students from Living Environment enter Regents Chemistry. Some fail or decide not to take a more rigorous course.
Also there is the difference in the scoring rubrics.
Living Environment 2020 Scoring Rubric:
Passing = 41 /85 = 48% correct gives you a 65!
2022 Regents Chemistry Rubric:
Passing = 50 /85 = 59% correct gives you a 65!

Whoosh bottle Demo Notes:
Once the I have the alcohol in the gas phase, which has now mixed with the oxygen in the air inside the container I ignite the flammable mixture by providing a spark and the combustion reaction begins. This is an example of an spontaneous reaction that releases energy exothermically, (exergonic reaction). Here is the chemical change that takes place:
2CH3OH(l) + 3O2(g) →. 2CO2(g) + 4H2O(g) + Energy Alcohol Oxygen carbon dioxide water
(l) = liquid, (g) = gas
Why is oxygen needed??
