It is not hard at all; it is a gas.
No, you can buy Hydrogen peroxide in any drugstore.
This reaction is a single displacement reaction, where magnesium displaces hydrogen in hydrochloric acid to form magnesium chloride and hydrogen gas.
No hydrogen peroxide can not cure cancer. It would be good if it could. It has been tested in a controlled medical test and did not work. The body does not create the same type of arteries, veins, and capillaries in a cancer that it does everywhere else. That makes it hard to get any type of chemical to a cancer. Cancer cells would need a hydrogen peroxide receptor for the chemical to use to enter the cell. It would be hard for hydrogen peroxide to get to the cancer and hard for it to get inside once it got there. The only chemicals that can work against cancer will be poison chemicals that mimic chemicals the cancer cells need.
Water (H2O) contains hydrogen and oxygen. There for its element sign id H2O. H2Os combination of atoms is 2 hydrogen atoms and one oxygen atom.
when you put the magnesuim in th test tube and you put an irritant in then you mix and hold the top hard to collect the gas and it makes a little sound pop.the gas is called hydrogen. hopes this heps
i think it's hard
Hard to store large quantities of pure hydrogen, very volotile
Hydrogen is highly inflammable. So it is used as a fuel. Also because hydrogen is colourless and odorless, it is hard to identify leaks.
They are too expensive and are hard to find.
Because hard margarine has been hardened by reacting it with hydrogen, whilst soft margarine hasn't.
If you have studied hard in life science you should know this but the real answer is that yes the nebular hypothesis was made by helium and hydrogen..
The only answer is it is far too hard to scrape hydrogen off everything else and compress it into fuel.
It isn't hard to get hold of Hydrogen. Simply put a current of electricity through water and you will split the two hydrogen atoms from the oxygen atom. I think you may be mistaking Hydrogen for Helium. Helium cannot be manufactured its a by-product of natural gas that has been distilled in radioactive decay for a very long time and you cant take one element and turn it into another.
Hydrogen, at STP, is a gas. So under those conditions it could be called 'soft'.
No, you can buy Hydrogen peroxide in any drugstore.
A molecule of ethane with one hydrogen missing. If you can find a spare OH to stick on there instead of just a hydrogen, then you have a complete molecule of ethanol, which is much more interesting to have at the end of a hard day in the lab.
You don't really need hydrogen in elemental form. You do need hydrogen to make proteins and nucleic acids (and lots of other compounds), but normally you'll get all you require in your diet ... hydrogen is the most abundant element in the universe, so it's kind of hard to run low on.
