Determination of the Percent Oxygen in Air

The experiment for today is determination of percent oxygen in air. Here is a video  as reference.




What’s going on?
Air is composed of Nitrogen - about 78%, Oxygen
about 21%, Argon about 1% and other gasses.
These gasses compose 100% of the air so they exert
100% of the pressure. IN the test tube, at the
beginning, there was the same pressure inside the
test tube as outside. As the steel wool started to
rust*, the oxygen was taken out of the air, therefore
the pressure was reduced. Over time, the pressure
was reduced by the percentage of oxygen
removed…. about 21%. As the pressure drops, the
pressure on the outside of the test tube pushes the
water level up inside the test tube.

SUDOKU

The activity for today is Sudoku.

Sudoku originally called Number Place, is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called "boxes", "blocks", "regions", or "sub-squares") contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a unique solution.
