Video show how to set up a cool demonstration for exothermic reactions or stochiometry. A bottle is filled with water, then the water is displaced with 1/3 oxygen and 2/3 hydrogen. The oxygen and hydrogen are made with household products.
If the water is steam then you should seal the bottle and show a timelapse of the steam converting into water so that i can actually see if you made water!
If oxygen wants an 8th electron to fill its outer valence shell and hydrogen wants its 2nd electron to fill its shell, why are these not just forming a covalent bond. Why does there have to be a flame to make the reaction take place. What would happen if these were left together in the bottle for a long time? Is there a way to make this reaction take place without a catylist?
+colton donisthorpe The amount of water is small and is steam. To make 18 ml of water you would need about 44 liters of hydrogen and 22 liters of oxygen. That would be one heck of an explosion.
the real question is can you drink it? others have asked here also but i see no answer. probably because you don't want to legaly liable if someone tries to drink it. but could you answer it theoreticly? could you drink it? sorry for my english. no spelling correction here.
Am I right in saying that when the bonds in the reactants (Hydrogen and Oxygen) are broken, energy is taken in (endothermic). However, when the bonds in the product (water) are made, energy is given out (exothermic). Therefore as the overall energy change is a balance between the energy taken in and the energy given out the reaction is exothermic as more heat is given out than taken in???????
"Other mixtures of hydrogen and oxygen will not be as loud because the reaction will not be in balance." Add something like "so the extra hydrogen or oxygen will not have anything to react with" after that to explain, since someone might think that if the proportion is not right and a mixture is unbalanced, it will make it go out of control even more, or make it almost not work at all.
1 oxygen atom is 16 times heavier than 1 hydrogen atom. Therefore, the ratio of 2 Hydrogen atoms to 1 Oxygen atom in water is on an order of a 1 to 8 ratio, and not a 2/3 to 1/3 ratio as stated in your video.
+Kevin Thomas Mass does not play a part in the volume of an ideal gas. One mole of gas is about 22.4 liters. For hydrogen the mass of those 22.4 liters is 2 grams. For oxygen, the mass is 32 grams. For water as steam, it is 18 grams. The cool thing is that because they are gases it is a simple volume ratio for the reaction.
i could make water too, but i need water, here's how: i drink some, few hours later, i make some! Unfortunately mine won't explode :( idk if that a good thing or not, cus it might explode too soon, lel.
Lol this is a pathetic explosion! My teacher did one and completely destroyed a plastic bin. Look for a video with a much higher amount of oxygen and Hydrogen! It will blow plastic bins up like the tan one they are using :)
