Is volume additive or non additive?
Volume is not an additive property because volume is a physical property that depends on the interactions of molecules.
What does it mean when volumes are additive?
Most students would initially predict that the new solution should have a volume of 500 mL; i.e., the two volumes are additive. This implies that the molecules in the two original volumes must now be closer together in the new solution.
Is specific volume an additive?
In chemistry, volumes are not always additive. (2) An appreciable amount of solid is dissolved in 100.0 ml of water, and the resulting volume of the solution is less than 100.0 ml. (3) 50.0 cm3 of a gas is added to 50.0 cm3 of a gas.
Why is mass additive and volume is not?
Mass is additive. That is, when you add two separate masses together, the total mass is the sum of the two individual masses. Volume isn’t always additive.
Are volumes of pure liquids additive?
– volumes of the pure components are not additive.
What do you mean by volume fraction?
The volume fraction (percentage by volume, vol%) is one way of expressing the composition of a mixture with a dimensionless quantity; mass fraction (percentage by weight, wt%) and mole fraction (percentage by moles, mol%) are others. …
Are moles additive?
If one adds 1 mole of NaCl and 1 mole of CaCl2 to a final adjusted volume of exactly 1 Liter in water, the chloride ion concentration would be additive (1 mole of Cl- from NaCl and 2 moles of Cl- from CaCl2). So, yes, in some situations, various ‘solutes’ are indeed additive on a molar basis.
Can you combine two liquids and have a volume less than the sum of the volumes when you started?
Concept: The total mass of substances does not change during a chemical reaction. When one volume of liquid is mixed with another volume of liquid that is less dense than the first, the total volume of the two liquids will not be the sum of the two individual liquids.
What is the difference between specific volume and volume?
Volume is a thermodynamic property of a substance. Specific volume is the volume of a unit mass of a substance. The difference between volume and specific volume is that volume is an extensive property whereas specific volume is an intensive property.
What is volume in gases?
Gas volume means the volume of gas as measured at 14.73 psia and 60 degrees Fahrenheit. When a given volume of carbon dioxide gas, expressed at these standard conditions, is dissolved in the same volume of liquid, that liquid is said to have “one volume” of carbonation.
Is mass always additive?
yes. although to be specific, this is the ‘invariant mass’ which is not additive. Conversely, the ‘relativistic mass’ is additive.
Is mass an additive property?
Mass (m) is an additive property in the sense that the total mass within a system can be simply determined by adding up the mass of each individual substance that’s in it.
Are volumes additive or non-additive?
There is no reason for volumes to be additive. Dilute solutions will be rather close. Volumes are never additive unless we are speaking of pure substances. What you’re actually asking is whether they significantly non-additive. It depends on what you’re measuring volumes for, the size of your solutions and the accepted uncertainty.
What is non additive nonadditive?
non·ad·di·tive | \\ ˌnän-ˈa-də-tiv \\. 1 : not having a numerical value equal to the sum of values for the component parts. 2 : of, relating to, or being a genetic effect that is not additive nonadditive effects of epistasis.
What is the difference between starting volume and Mixture Volume?
Starting volumes are additive. Mixture volume is unchanged. Molecules look alike to one another. Mixture is an ideal solution.
What is Amagat’s law of additive volumes?
Amagat’s law of additive volumes is the law of partial volumes. The law relates the total volume of a mixture with the volumes of individual components. Amagat’s law is very similar to Dalton’s law of partial pressure.
