How was hydrogen Discovered?
Hydrogen was first discovered by Henry Cavendish in 1766 when he isolated it as a unique substance during his experiments on acids and metals. He observed that hydrogen released during the reaction of metals with acids produced a gas that burned easily.
What organic compounds are produced when materials containing carbon and hydrogen are burned?
Hydrocarbon is an organic compound which is entirely made up of hydrogen and carbon. Hydrocarbons are the main source of the world’s electric energy and heat because of the energy produced when they are burned.
What is the substance produced when metal is burned?
It depends upon the subsance being burned. Normally, the substance would end being some sort of oxide (O2 molecule being attached to the base molecule of what is being burned).
What substance do you get when you burn hydrogen?
When hydrogen is burned in the presence of oxygen, it produces water as a byproduct. The chemical equation is 2H2 + O2 -> 2H2O.
Where was hydrogen origianally found?
Hydrogen is the chemical element with atomic number 1, symbol H. In 1783 it was given its name when it was discovered that water is produced when hydrogen is burned.
When 4 g of burning hydrogen produces 36 grams of water how many kg of water is produced if the burn 100 kg of hydrogen?
For every 1 g of hydrogen burned, 9 g of water is produced. Therefore, if 100 kg (100,000 g) of hydrogen is burned, it will produce 900,000 g (or 900 kg) of water.
How much energy per gram of hydrogen is produced when hydrogen gas is being burned?
The combustion heat of hydrogeh (HHV) for 1 g is 141,8 kJ.
What does hydrogen transform into when burned?
When hydrogen is burned, it transforms into water vapor.
What does hydrogen transform into when it is burned?
When hydrogen is burned, it transforms into water vapor.
What is the gas produced when any metal reacts with acids?
Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
What color hydrogen is when burned?
Hydrogen burns with a pale blue flame. The blue color produced is due to the chemical reaction of hydrogen with oxygen in the air, emitting energy in the form of light.
Why is water produced when hydrogen is burned?
The combustion of hydrogen requires oxygen, which is supplied by the surrounding air. When hydrogen is combusted, it reacts with oxygen in the equation: 2H2 + O2 --> 2H2O with water (H2O) being the product
