What else can I help you with?
When hydrogen burns in air the change is chemical Give two reasons to support this assertion?
When hydrogen burns in air with H2+O2= H20
What happens to lime-water when you mix it with hydrogen and add a burning splint?
When lime-water is mixed with hydrogen and a burning splint is introduced, the mixture will produce a squeaky pop sound. This indicates the presence of hydrogen gas, as it reacts with oxygen in the air to create a small explosion. Lime-water itself does not react with hydrogen gas in this scenario.
Can anyone suggest a test for hydrogen gas other than burning splint?
Fill a balloon with the gas and see if it is lighter than air (only Helium and Hydrogen will make a balloon float...) Calculate the density of the gas (mass/volume)
What does not happen when light travels from water into air?
The following are some things that do not happen:The water decomposes into hydrogen and oxygen.The air gets sucked into the water, forming a whirlpool.The hydrogen in the water fuses, producing a multimegaton nuclear explosion.The nitrogen in the air reacts with the hydrogen in the water forming ammonia gas.The surface of the water becomes electrically charged.etc.
Where does oxygen come from when burning wood?
Oxygen in the combustion of wood primarily comes from the surrounding atmosphere. During the burning process, oxygen molecules in the air react with the carbon and hydrogen in the wood to produce heat, carbon dioxide, and water vapor.
What is the name of a substance formed by burning hydrogen and ethanol in air?
what is the substance formad when burning both hydrogen and ethanol in the air
What is formed when burning hydrogen in air?
When burning hydrogen in air, water vapor is formed as a byproduct. The chemical reaction can be represented as: 2H2 + O2 -> 2H2O.
How can you make water from hydrogen hydrogen from water?
Yes. You cannot get water from hydrogen alone. You need oxygen. Since oxygen is a part of the atmosphere, simply burning hydrogen in air will give you water vapor. Passing an electric current through water will split it back into hydrogen and oxygen.
Where did hydrogen gets its name?
Hydrogen in Greek translates as "water maker" referring to the fact that it is one of the two elements in water.And that water is the result of burning hydrogen in air.
When hydrogen burns in air the change is chemical Give two reasons to support this assertion?
When hydrogen burns in air with H2+O2= H20
Is burning of hydrogen in air chemical change?
Yes, burning of hydrogen in air is a chemical change because it involves a reaction between hydrogen and oxygen molecules to form water, releasing heat and light energy in the process.
What is a by-product of burning hydrogen gas?
There is only one product - water. Hydrogen burns in the oxygen in air to form hydrogen oxide or water vapour. 2H2 (g) + O2 (g) = 2H20 (g)
What happens to lime-water when you mix it with hydrogen and add a burning splint?
When lime-water is mixed with hydrogen and a burning splint is introduced, the mixture will produce a squeaky pop sound. This indicates the presence of hydrogen gas, as it reacts with oxygen in the air to create a small explosion. Lime-water itself does not react with hydrogen gas in this scenario.
What is old name of hydrogen?
Hydrogen has been known by the same name throughout history. It was named by Antoine Lavoisier in 1783 from the Greek words "hydro" (water) and "genes" (forming), reflecting its role in forming water.
Result of burning hydrogen sulfide?
Burning hydrogen sulfide produces sulfur dioxide and water as the main products. The reaction releases heat and light energy. Sulfur dioxide is a noxious gas that contributes to air pollution.
What is the bi-product of water and air from photosynthesis?
oxygen and water.oxygen from water when it splits into hydrogen and oxygen because only the hydrogen is used, and water from carbon dioxide that combines with hydrogen to make a carbohydrate,
Why is it when you exhale underwater you make bubbles?
because the bubbles are air the air can't fuse with hydrogen to become water because there is no excess hydrogen so it goes to the air as bubbles
