How much potassium nitrate should be heated to get enough oxygen required to completely burn 5 Litre of hydrogen at STP?

For every 2 moles of KNO3 heated, one mole of O2 is produced. Therefore, in order to have enough Oxygen to burn 5 liters of Hydrogen gas at STP, you would need to heat 0.2 moles of Potassium Nitrate (round to 0.2 moles since “5 liters” has only one significant figure) . Hope this helps!

How many moles of KNO3 must be heated?

Hence, 2332.5 moles of KNO3 K N O 3 must be heated to produce 93.3 kg of O2 .

What happens when potassium nitrate is burned?

… /Potassium nitrate/ decomposes on heating producing nitrogen oxides, oxygen, which increases fire hazard.

Does potassium nitrate decompose when heated?

When potassium nitrate is heated, it decomposes into potassium nitrite and oxygen.

How many moles of kno3 must be heated to produce 56.6 kg o2?

We need 1415.1 mol KNO3 to produce 56.6 kg of O2.

How many total moles of ions are released when the following sample dissolves completely in water?

Thus 2.202 moles of ions are released when samples dissolves completely in water.

How oxygen is prepared from potassium nitrate?

When Potassium Nitrate Is Heated, Potassium Oxide, Nitrogen, And Oxygen Are Produced As Products.

How flammable is potassium nitrate?

FIRE HAZARDS * Potassium Nitrate is noncombustible, however, it is a STRONG OXIDIZER and will accelerate burning when involved in a fire. * Use water only. DO NOT USE DRY CHEMICAL, CO2 or HALOGENATED extinguishing agents. * POISONOUS GASES ARE PRODUCED IN FIRE, including Nitrogen Oxides.

Is potassium nitrate flammable?

When potassium nitrate is heated potassium oxide nitrogen gas and oxygen are formed?

Problem: Potassium nitrate decomposes on heating, producing potassium oxide and gaseous nitrogen and oxygen: 4KNO3(s) ⟶2K2O(s) + 2N2(g) + 5O2(g) To produce 56.6 kg of oxygen, how many moles of KNO3 must be heated?
