How has hydrogen gas been made through chemical reactions?
strong acids like sulphuric acid reacted with metals like zincwater reacted with alkali metalselectrolysisetc.
What gives water when reacted with hydrogen?
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) .
What created when alkaline earth metals and water combined?
When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.
Which thing gives colourless gas that burns with pop sound on reaction with dilute hcl?
Zinc metal gives off a colorless gas (hydrogen gas) that burns with a pop sound when reacted with dilute hydrochloric acid.
What metals will evolved hydrogen when reacted to strong base?
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.
How many moles of hydrogen gas are produced when 0.066 mole of sodium is completely reacted?
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.
Does zinc displace hydrogen from cold water?
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.
What gas is given off when iron fillings are reacted with hydrochloric acid?
hydrogen
What is the gas given off as a product when zinc is reacted with hydrochloric acid?
Hydrogen
How can you make hydrogen from other chemicals?
Hydrogen can be produced from other chemicals through processes like steam reforming of natural gas or electrolysis of water. In steam reforming, natural gas is reacted with steam at high temperatures to produce hydrogen and carbon dioxide. Electrolysis involves passing an electric current through water to split it into hydrogen and oxygen.
Why is sodium metal not ordinarily reacted in the laboratory even with the dilute acid?
The reaction of sodium metal with water is highly exothermic. Hydrogen gas is liberated and autoignites from the heat. With an acid, even more hydrogen gas is liberated and ignites.
What is the gas formed when Mg reacted with sulfuric acid?
Mg + H2SO4 -> MgSO4 + H2 Hydrogen gas.
