What happened when the splint was brought to the mouth of the first bottle of hydrogen collected?
When the splint was brought to the mouth of the first bottle of hydrogen collected, the hydrogen gas ignited with a pop sound, indicating that hydrogen is a highly flammable gas. This reaction is due to the combination of hydrogen gas with oxygen in the air, creating water vapor.
How hydrogen detected in the carbon and hydrogen test?
To test for hydrogen in the given substance, a dry sample is needed. Burn it in excess of oxygen. If the vapour turns white copper sulfate into blue colour, it indicates that there is water in present in the vapour. Hence, the organic compound contains hydrogen.
A 200 ml sample of hydrogen is collected over water at 745.5 torr and 290K If the vapor pressure of water at 290k is 14.5 torr What is the volume of dry hydrogen at STP The answer is 181m?
To find the volume of dry hydrogen at STP, we need to correct for the presence of water vapor. First, calculate the pressure of dry hydrogen by subtracting the vapor pressure of water from the total pressure: 745.5 torr - 14.5 torr = 731 torr. Then, apply the ideal gas law to solve for the volume of dry hydrogen at STP: V = (200 ml * 731 torr * 273 K) / (290 K * 760 torr) ≈ 181 ml.
How do you strip hydrogen from water?
To strip hydrogen from water, a process called electrolysis is used. In electrolysis, an electric current is passed through water to split it into hydrogen and oxygen gases. The hydrogen gas is collected at the cathode while the oxygen gas is collected at the anode.
Can you collect hydrogen gas over water?
Yes, hydrogen gas can be collected over water by displacing the water in a container with the gas. Hydrogen is less dense than air so it will displace the water, allowing the gas to be collected in the container while the water is pushed out.
Why the hydrogen gas collected from the reaction of the metal with acid is called wet hydrogen gas?
Wet hydrogen is collected over a water surface.
Why the hydrogen gas collected from the reaction of the metal with acid is referred to as wet hydrogen gas?
It is called wet hydrogen gas because it is collected over water.
What happens to the hydrogen produced from the splitting of water?
Hydrogen is released in the atmosphere.
Why hydrogen cant be collected by the downward displacement of air?
Hydrogen is lighter than air, which is why it rises upwards in the atmosphere. When collected by the downward displacement of air, the denser air prevents the lighter hydrogen from being fully collected as it continues to rise. This method is more effective for gases that are denser than air.
How was it proved water is composed of hydrogen and oxygen?
by electrolysis, hydrogen and oygen ions were collected in different nodes

What is collected from the Cyprus lakes when they dry up in summer?
Salt
How do you make dry ammonia?
Dry Hydrogen and dry nitrogen gas in the Haber process
