Can magnesium replace after adding into acid?

yes if put into HCl it will replace the H and produce hydrogen gas and magnesium chloride


What chemicals produce hydrogen gas?

Water. When you put electrodes into water and pass a current, you produce hydrogen and oxygen gasses.


What is the reaction when ammonium hydrogen carbonate is put in water?

A water solution is obtained.


How is it possible then for water which is composed of hydrogen and to put out fires?

The bonds between the hydrogen and oxygen is too strong to be destroyed by combustion. Add: The chemical properties of water are different from the properties of hydrogen and water separately. Therefore, water does not support combustion as oxygen does, and water does not explode as hydrogen does.


What would happen if water replace in catalase activity?

If water were to replace hydrogen peroxide in catalase activity, the catalase enzyme would not function as intended. Catalase specifically catalyzes the decomposition of hydrogen peroxide into water and oxygen, so substituting water would eliminate the substrate needed for the reaction. Consequently, the enzyme would be inactive, and the crucial protective role of catalase in breaking down harmful hydrogen peroxide would be compromised.


Hydrogen is realesed when sodium reacts with water?

Yes, sodium is more reactive so sodium ions replace hydrogen ionsNa+ + H2O>H+ + NaOH +H2O


What happens if you put hydrogen in water?

Not much! Some of it, a tiny amount, might bond to the water molecules, but as water already has its standard H2O composition, most extra hydrogen will simply bubble out, hydrogen being lighter than water. For details and discussion of hydrogen bonding with water, see Related Links below these advertisements. The solubility of hydrogen gas in water at 0oC is 0.0019 grams of hydrogen per kilogram of water. At 60oC, the solubility is 0.0012 grams of hydrogen per kilogram of water. That is a tiny amount that will dissolve in the water. The rest would simply bubble out as the previous answerer said. Also, most likely, the water would be already saturated with hydrogen since it was in contact with the atmosphere, which contains hydrogen; so unless you took steps to purge the hydrogen from the water to get water not already saturated with hydrogen, all of the added hydrogen would bubble out since the water would be already saturated with hydrogen.


How is hydrogen water made and what are the steps involved in the process?

Hydrogen water is made by infusing water with molecular hydrogen gas. The process involves using a hydrogen water generator or hydrogen water bottle, which electrolyzes water to produce hydrogen gas that dissolves into the water. This can be done by simply adding hydrogen tablets or using a hydrogen water machine to create hydrogen-rich water.


Why is water formed when you mix hydrogen and oxygen gases?

Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.


What happens when it is put in water potassium?

Potassium metal will react violently with water to form KOH and hydrogen gas. Due to the heat released by the reaction - the hydrogen gas will ignite. So: placing potassium in water will cause a fire!


If you Replace one of the hydrogen atoms in a water molecule with a carbon group what does it produce?

If the replacement group has the empirical formula CnH(2n +1), the product is an alcohol.


Can you get water from hydrogen?

You can get water from hydrogen if you combine the hydrogen with oxygen atoms.
