States that the amount of pressure exerted by a gas in a mixture is proportional to the percentage of the gas in the mixture?
Dalton's law
The relative vapor pressures of the mixture components are important in GC Gas Chromatography but not in LC Liquid Chromatography Why is that?
In Gas Chromatography, before you can correctly separate and identify the components, you need to vapourise the mixture first. How fast a substance vaporises is dependent on their vapour pressure. In Liquid Chromatography, there is no need to vapourise the mixture and hence vapour pressure is not important here.
What best defines partial pressure in a mixture of gases?
the amount of open space which allows a volumn or substance to move
What is the partial pressure of a gas in a mixture of gas?
The pressure exerted by one gas in a mixture (apex)
What is the partial pressure of a gas in a mixture of gasses?
The pressure exerted by one gas in a mixture
States that the amount of pressure exerted by a gas in a mixture is proportional to the percentage of the gas in the mixture?
Dalton's law
What is qualitative and quantitative analysis in gas chromatography?
Qualitative analysis is to determine the type of gass is in a gas mixture. Quantitative determines the amount (concentration) of the different gases in the gas mixture
How can nitrogen gas be separated from the mixture of nitrogen gas and a little amount of oxygen gas?
Copper(II) oxide, CuO, can be used.
Is oxygen and gas a mixture?
No. It is an element.Oxygen is a pure gas that is mixed with other gases to produce the atmosphere to support human life. Deep sea divers use a mixture of oxygen and other gases to enable them to dive deep - it is a very important science. Our blood captures the oxygen we breathe in and binds it safely to the transport molecule called haemoglobin.
Is natural gas element or mixture or compound?
Natural gas is a mixture.
Is a Nobel gas a mixture?
mixture
What happens if sodium reacts with sulphuric acid?
The sodium will react violently with the sulfuric acid, releasing hydrogen gas which is then ignited by the heat of the reaction. The reaction will also produce sodium sulfate, sodium bisulfate, or a mixture of the two depending on how much acid there is relative to the amount of sodium.

The of any amount of a solid liquid or gas relative to its volume is called it's density?
VOLUME
Why do sparkplugs turn black on a lawnmower and how do you fix it?
Black spark plugs indicate that the fuel mixture is too rich in fuel. White spark plugs indicate that the fuel mixture does not have enough fuel. The proper color for spark plugs is tan. Black spark plugs also indicate that oil is entering the combustion chamber and burning. If your lawnmower is 2 stroke, this is probably normal due to the gas/oil mix of fuel added to the tank. If your lawnmower is 4 stroke, you need to adjust the carbs to reduce the amount of fuel in the fuel/air mix.
