What is displacement method in science?
It is actually a means of finding the volume of an irregular shaped object. A graduated cylinder and a specific amount of water is used. Then the object is slid in. Water is measured and you figure out the difference of measures. Example: you start with 50 ml. than add the object. if it is now 25ml, the volume is 5
What apparatus would you need for the hydrogen test?
You do the same test as you would have done in year 7, the pop test. Invert a test tube and fill partially with the gas then place a lit match or candle at the bottom if you hear a pop you have hydrogen. just don't be like my old teacher and fill it to the point half the room catches fire. Hope this helps
Is H a molecule?

What elements does alcohol contain?
hydrogen, carbon, oxygen
Is a double displacement reaction hydrogen bonding?
The double displacement reaction is not related to hydrogen bonding.
Why some metals react with acids in terms of displacement of hydrogen?
The metals which are more reactive than hydrogen displaces hydrogen from its solution. It is also an example of displacement reaction.
Gas collected by displacement of water?
hydrogen
Why hydrogen cant be collected by the downward displacement of air?
because hydrogen is collected by the upward displacement of air although it is 14.5 times lighter than air B)
Which kind of metal applied hydrogen displacement?
alkili metals
Replacement of hydrogen from water by sodium is an example of what?
Single displacement!
What does displacement of hydrogen mean?
When a metal does react with water or hydrochloric acid , it drives hydrogen out and take its place
What type of chemicalreaction is between hydrogen sulphide and oxygen?
Displacement reaction
Explain why hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water?
All reactive metals undergo a similar single-displacement reaction with water. They all form hydrogen.
How is hydrogen gas prepared in the laboratory?
just use the hydrogen cylinder
What color is a hydrogen cylinder?
red
What is an electronic polarization of hydrogen atom?
Displacement of electrons of the atoms of hydrogen leads to a positive charge on the hydrogen molecule. It can be even split ed off into cations.
