What else can I help you with?
Is gas homogeneous heterogeneous or a pure substance?
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
What is the partial of a gas in a mixture of gases?
The partial pressure is the pressure exerted by just one gas in the mixture.
What does Dalton's law partial pressures say?
The total pressure of a gas mixture is the sum of the individual pressures.
What is Daltons law on partial pressure?
Dalton's law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas in the mixture. Each gas in a mixture exerts a pressure that is independent of the other gases present.
Is the air you breathe homogeneous or heterogeneous?
is heterogenous because it is composed of many different gases. To be homogenous it would have to be composed of a single gas.
The proportion of pressure that a single gas exerts within a mixture?
In a mixture of gases, for example 70% Helium and 30% Oxygen, the pressure exerted will be split 70/30 between the gases, respectively. As John Dalton discovered, the proportion of these pressures is the proportion of the number of molecules of the gas within the mixture.
Is gas homogeneous heterogeneous or a pure substance?
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
What is the partial of a gas in a mixture of gases?
The partial pressure is the pressure exerted by just one gas in the mixture.
What is the difference between gas and air?
Pure air is a mixture of several gases that are invisible and odourless. It consists of about 78% nitrogen, 21% oxygen, and less than 1% of argon, carbon dioxide, and other gases - as well as varying amounts of water vapour.
What is a constituent gas?
A constituent gas is a gas that is a component of a mixture or compound. It is one of the individual gases present in a larger gas mixture.
What does Dalton's law partial pressures say?
The total pressure of a gas mixture is the sum of the individual pressures.
What is a solid mixture and a gas mixture?
An example of a solid mixture is a metal alloy, such as bronze, which is a mixture of copper and tin. An example of a gas mixture is air, which is a mixture of nitrogen, oxygen, carbon dioxide, and several other gases.
What is the air-gas mixture?
It is a mixture of air with one or more other gases.
What is air-gas mixture?
It is a mixture of air with one or more other gases.
How can gas be a part of mixture?
There are three ways. Some mixtures are gases themselves, and air is the most common one. Some mixtures are partly gases and partly liquids. Also, gases can dissolve into liquids, like oxygen in water.
What is the partial pressure of a gas in a mixture of a gases?
The partial pressure is the pressure exerted by just one gas in the mixture.
What is the partial pressure of a gas in the mixture of gases?
The partial pressure is the pressure exerted by just one gas in the mixture.
