The question is rather poorly asked. It should be ' What other gas reacts with hydrogen to form water? '
The answer is oxygen.
Hence is the balanced reaction eq'n.
2H2(g) + O2(g) = 2H2O(l) .
Oxygen
Water is formed. When hydrogen and oxygen gases are mixed, nothing happens, until a flame is put into the mixture. Whereupon there is a 'pop' and water is formed. Here is the BALANCED reaction eq'n 2H2(g) + O(g) = 2H2O(l) The 'pop' test is a classic lab. test for hydrogen . If the gases are mixed in large quantities, then the 'pop' becomes an explosion. NB Fill two balloons , one with hydrogen and the other with helium. With a piece of string allow then to float in the air/room. Put a lighted taper to the helium filled balloon. It will just pop and fall to the ground. Put a lighted taper to the hydrogen filled balloon. It will pop with a flash of flame and a loud bang.
The 'pop' test. To test for hydrogen , have a sample in an upturned boiling/test tube, hydrogen is lighter that air, put a lighted splint/taper to the mouth and it will 'pop' This is the classic hydrogen test.
strong acids like sulphuric acid reacted with metals like zincwater reacted with alkali metalselectrolysisetc.
Zinc does not displace hydrogen from cold water, as zinc is lower in the reactivity series than hydrogen. However, if zinc is reacted with an acid, such as hydrochloric acid, it will displace hydrogen gas.
NO!!! Water is a COMPOUND, composed of the atoms of the elements hydrogen and oxygen. Two hydrogen atoms are electronically combined with one oxygen atom , hence forming the compound water (H2O). Structurally it is ' H-O-H '. NB It is NOT a mixture. In mixtures there is no electronic combination of atoms.
Nope, and if your gunna ask if you can drink it, well drink some and tell me.
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
Hydrogen will be liberated.
The balanced chemical equation for the reaction between sodium and water is: 2Na + 2H2O -> 2NaOH + H2 This means that for every mole of sodium (Na) reacted, one mole of hydrogen gas (H2) is produced. Therefore, when 0.066 mole of sodium is reacted, 0.066 mole of hydrogen gas will be produced.
When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.
Aluminum is a silvery metal that will evolve hydrogen gas when reacted with a strong acid. Aluminum will also evolve hydrogen gas as a product of its reaction with a strong acid.
