Contains two or more gaseous liquid or solid substances blended evenly throughout the mixture?
Homogeneous because in my science book it says a homogeneous mixture contains two or more substances that are evenly mixed on a molecular level but still are not bonded together
Does the pressure is affected if is difference liquids?
Yes. Pressure of a liquid could be considered in two ways. 1. The subsurface pressures. 1 ATM is the pressure of our atmosphere on earth which is equivalent to a pressure of 14.7 PSI. This is the same pressure as would be exerted by 34 feet of water. So, if one dives to 34 feet, one would actually feel 2 ATM of pressure or 29.4 PSI TOTAL. However, this is the same pressure as is developed by 760mm (or 30 inches) of mercury. So a diver would feel the same 2ATM (29.4 PSI TOTAL) in less than 3 feet of Mercury. 2. Partial Pressures & Vapor Pressures. The partial pressures and vapor pressures are dependent on the type of liquid and the temperature. When the partial pressures or vapor pressures reach 1 ATM, the substance boils. So, for example, the vapor pressure of Methanol at 64.7 °C, 148.4 °F is 1 ATM, and thus it will boil. However the vapor pressure of pure water at the same pressure is significantly less than 1 ATM, and the water does not boil. This is used to distill substances. However, as with water/alcohol mixes, the water does exert a certain vapor partial pressure on the mix and one typically gets a mixture with a significant fraction of water in the final product.
In a gaseous mixture of massive molecules and light molecules with the same average kinetic energy which have the greater speed?
light molecules
What is the difference between air and vacuum?
Vacuum refers to a volume of space that is essentially empty of matter,such that is gaseous pressure is much less than atmospheric pressure. while AIR is the mixture of oxygen, nitrogen,and other gases that are consistently present around us.
How could you prove that white light contains a mixture of light with different colors?
By using a prism.
What law states that the total pressure of a confined gaseous mixture equals the sum of individual gas pressures?
Daltons law
What is Daltons law on partial pressure?
The total pressure of a mixture of gasses is the sum of the pressures of each gas in the mixture (Apex)
How does the total pressure of a mixture of gases relate to the partial pressures of the individual gases in a mixture?
total pressure = sum of all partial pressures.
What does Dalton's Law of Partial Pressures say?
The total pressure of a gas mixture is the sum of the individual pressures.
What law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of its individual gases?
The pressure of each gas in a mixture is called the partial pressure of that gas.
What is the partial pressure of a gas pressures in the mixture?
The partial pressure is the pressure exerted by just one gas in the mixture.
What is the partial pressure of a gas in a mixture of gas?
The pressure exerted by one gas in a mixture (apex)
What does Dalton's law of partial pressures?
The total pressure of a gas mixture is the sum of the individual pressures.
Does Dalton's law of partial pressures state that total pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture?
Yes. That is True. Dalton's Law is: that pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture. Reference: Human Anatomy and Physiology Marieb and Hoehn
How does the total pressure of a mixture of gases relate to the partial pressure of the individual gases in a mixture?
total pressure = sum of all partial pressures.
Is a homogeneous mixture?
A mixture which only contains substances which are in the same phases/state. eg, a gaseous mixture or a mixture of two aqueous solutions.
What Dalton's law of partial pressure?
The total pressure of a mixture of gases is the sum of the pressures of each gas in the mixture.Apex
