depending on how well you are able to remove the test tube from the beaker, a little or a significant amount of water may be present in the test tube. But that really doesnt matter and does not affect your test for oxygen.

Why does the gas moves upward and does it mean that the oxygen that is being produced in ocean will move upward and if this happens then how the oxygen in the water does not finish.

@TheSingtangpaScienceGuy 3 жыл бұрын

Gas moves upward because it is lighter than water. At the same time , you shud know that there is something called "Dissolved Oxygen (DO)" which is oxygen that remains in water in a dissolved for. Not all 100% oxygen prodiced in oceans escape the water, some amount dissolved in water for the aquatic organisms to use.

@PeterPete 2 жыл бұрын

photosynthesis is a great idea to explain how plants interact with their natural environment but it's only an idea. The oxygen in the above demo came from the NaHCO3 that was added to the water and we all know there is no NaHCO3 in a plant's natural environment! So the process of photosynthesis is a great idea supported by contrived demonstrations. However what's even more amusing is that science has not come up with any mechanism whereby the alleged oxygen produced by plants bonds with nitrogen to form an air molecule!! Science is insanely funny!!

Hello! Nice video! I made some calculations about conversion of carbon dioxide to glucose and release of oxygen. Lets take into account that 50 000 L of air and calculate amount of carbon dioxide in it V (CO2) = 50 000 л * 0,04% CO2 = 2000 л CO2 100% quantity of CO2 = 2000 L / 22,4 L / моль = 89.285 mol 6CO2 + 6H2O = c6h12o6 (glucose) + 6O2 quantity of substance of glucose = 89.285 mol / 6 = 14.88 mol weight (glucose) = n * Mr = 14.88 mol* 180 g / molглюкозы = 2,678g and as a side product it releases 2000L of O2/ How this number was obtained? According to the equation amount of O2 is equaled to CO2 = O2 = 89.285 mol/ 22,4 L / mol= 2000 L

The oxygen is released thru the cut end of the stem. So we invert it so the bubbles neatly float up and collect in the test tube.

how the elodea plant give off oxygen during photosynthesis?

@TheSingtangpaScienceGuy 3 жыл бұрын

All green autotrophic plants produce O2 as a side product of photosynthesis. Produced within chloroplasts, they eventually escape through the stoma and other open areas of the plant such as cut surfaces like those of the stems of the plants we are using in this experiment. Escape of oxygen gas through the cut end of the stems is a sign that photosynthesis is taking place in the plant.
