This would happen because of the process of diffusion. Hydrogen molecules would move from the hydrogen test tube where they are highly concentrated to the air test tube where their concentration is low.
Yes it does. However, it takes a much longer period of time to get the magnesium to give off hydrogen particles. After a solid 45 minutes you might get a pop, but it's part of the Alkaline Earth Metals which means yes... it will eventually pop.
your die within minutes
I would consider that positive. But if you are unsure, take another test.
no
There is a total of 24 hours in each day with each hour containing 60 minutes.
Water molecules contain two polar ends known as dipoles which are caused by the atoms that make up water. The chemical composition of water is H20 meaning that there are 2 hydrogen atoms bound to one oxygen atom. This bonding does not occur in a straight line and the bond angle between the 2 hydrogen atoms is 109 degrees and 27-28 minutes I believe. The hydrogen Atoms have a positive charge while the oxygen atoms have a negative charge which helps to hold the atom together (along with hydrogen bonding). If you look at a diagram of the structure of water, you will see that the hydrogen atoms are more on one side of the molecule while the oxygen is on the other. this makes one side slightly positive while the other side becomes slightly negative
Hydrogen gas is non-toxic but it is highly flammable (or explosive) so it could easily cause you to burn to death; in addition, if you were to breathe pure hydrogen you would die in a few minutes from lack of oxygen.
Consider this result null and void and redo the test the next morning. THere's a reason why all pregnancy tests state NOT to read results after 10 minutes, it can create a false positive where it reads positive but you're not pregnant. GOod luck
usually about 2 minutes
120 minutes.
hydrogen is a chemical. Hydrogen, the most basic of all chemical elements, contains only one proton, 1 electron and no neutorns. Hydrogen is actually the oldest element in the universe, being formed between 3 and 20 minutes after the Big Bang. These are only a couple of the interesting facts about hydrogen, lets get to some more.
