How do you remove excess hydrogen from a apparatus where oxygen should be collected?
fill with water
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
In what quantities is oxygen in ice?
yes it does, as ice is the frozen state of water and water's chemical formula is h2o, where "h" is hydrogen and "o" is oxygen, but the chemical properties of hydrogen are not same as in "h2" cause it has been reacted with oxygen and lost its original chemical properties as single atom bond....
What is the most common molecule in the human body is made of what element?
Oxygen and Hydrogen
What do you get when you electrolyse water?
Hydrogen and oxygen are the products of electroysis of water .
What gives water when reacted with hydrogen?
Oxygen
What gas gives water when reacted with hydrogen?
Oxygen
What happens if hydrogen is reacted with oxygen?
The Hydrogen will burn fiercely with a lambent blue flame and water will be produced.
How could you prove that something is hydrogen?
If it reacted with oxygen then it would form water
What reacted with oxygen to form Us historys worst aviation?
hydrogen when the hindenberg blimp blew up
Is wtaer considered an element?
No, Water is a compound of Hydrogen and Oxygen, which are elements, but when reacted together: 2H2 + O2 = H20
How do you remove excess hydrogen from a apparatus where oxygen should be collected?
fill with water
What is a limited reactant?
With any chemical reaction you have reactants and products, for this question I'll use the example of the formation of water from it's parts, Hydrogen and Oxygen. The equation would look like this: 2H2 (g) + O2 (g) -> 2H2O (l) Let's say you start out with 3 moles of Hydrogen and 1 mole of Oxygen. From the reaction you can see that for every mole of O2 that reacts, 2 moles of H2 are reacted. This means that after your mole oxygen reacts, you are still left with a mole of excess Hydrogen. Thus, Hydrogen is considered the excess reactant, and Oxygen is considered the limited reactant. In short, the limited reactant is whichever reactant you will use up in the reaction first.
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
How has hydrogen gas been made through chemical reactions?
strong acids like sulphuric acid reacted with metals like zincwater reacted with alkali metalselectrolysisetc.
What is product when hydrogen abd oxygen react?
Given the energetics presented above, there is a strong thermochemical bias for the production of water over hydrogen peroxide when H2 and O2 are reacted together.
How much water wold form if 14.8 grams of hydrogen reacted with 34.8 grams of oxygen?
45 g water are obtained.
