What is electrolysis used to make?
Electrolysis is used to separate sodium metal from table salt. It is easier to harvest hydrogen from fossil fuels, than it is to separate hydrogen from oxygen using electroysis of water.
Why electrolysis of concentrated aqueous sodium chloride liberate chlorine rather than oxygen at the anode?
Bacon and eggs and orange juice!!
Why is electrolysis much more expensive than using a blast furnace?
electrolysis requires a lot of electrical energy, however this is not the same with reduction with carbon (blast furnace), which is a lot cheaper than electrolysis, but not always the most practical. :)
What happens when oxygen is prepared from hydrogen peroxide without adding a catalyst?
Hydrogen peroxide purchased from a store or science supply house has been stabilized so that expected loss due to spontaneous decomposition into oxygen and water is less than 3% per year. Without adding a catalyst, you will have to wait a very long time to collect the oxygen from a sample of hydrogen peroxide.
What is oxide an element or a compound?
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
Why does using sodium bicarbonate as electrolyte when performing electrolysis of water produce less than one half volume oxygen for every one volume of hydrogen produced?
Because the electrolysis of water reaction always produces twice as much hydrogen (by volume or by mole) as they do oxygen. H2O(l) -> H2(g) + 1/2 O2(g)
Do 6 billion grains take up more or less space than you expected?
Less space than I expected.

What is under frequency?
When the frequency is less than expected.
An oxygen deficient atmosphere has an oxygen concentration less than?
19.50%
Would the electrolysis process be useful on the moon?
Electrolysis separates water molecules into hydrogen and oxygen. This is a useful process on the moon because we can use water on the moon to supply a colony with a reliable local source of breathable oxygen and burnable hydrogen, rather than having to fly it all the way from earth.
If your self employment income is less than expected do you pay less estimated taxes?
Yes
Will the energy produced on combustion of hydrogen be more than the energy used for separation of hydrogen from water through electrolysis?
In theory, the energy produced by creating four oxygen-hydrogen bonds after breaking two Oxygen-oxygen and hydrogen-hydrogen bonds in the reaction O2 + 2H2 -> 2H2O (hydrogen combustion in oxygen) is exactly the same than the energy needed to break four oxygen-hydrogen bonds to create two oxygen-oxygen and hydrogen-hydrogen bonds in the reaction 2H2O -> O2 + 2H2 (water electrolysis) However, you will always have great energy loss during electrolysis (an important part of your energy will be used to warm up your water) and in getting back your energy from your oxygen and hydrogen gas (a combustible battery or a motor will warm up too).
Was y2k for real?
There were some real problems, but less than expected.
Why does the voltage reading of 110 circuit is less than expected?
A load or a resistance
Why oxygen have less ionisation enthalpy than fluorine?
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).
