What properties of a substance effect how substances in a mixture separate
IrinaVladis [17]
Mixture is a material made up of two or more different substances which are mixed. A mixture refers to the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensionsand colloids.[1][2]

Mixtures are one product of mechanically blending or mixing chemical substances such as elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup.[3]Despite that there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by using physical (mechanical or thermal) means. Azeotropes are one kind of mixture that usually pose considerable difficulties regarding the separation processes required to obtain their constituents (physical or chemical processes

A 15.0 L tank of gas is contained at a high pressure of
Inessa05 [86]

Answer:

20.5 torr

Explanation:

Given parameters:

Volume of tank  = 15L

Pressure of tank  = 8.2 x 10⁴torr

Volume of empty chamber = 6.0 x 10⁴L

Unknown:

New pressure of the gas in this chamber = ?

Solution:

To solve this problem, a good knowledge of the gas law will suffice here. Since pressure and volume relationships are under consideration, the Boyle's law is the proper gas law to apply.

 Boyle's law states that "at constant temperature, the volume of fixed mass of gas is inversely proportional to the pressure of the gas".

Mathematically;

    (Pressure x volume) of tank  = (Pressure x volume ) of empty chamber

      15 x 8.2 x 10⁴   = Pressure of empty chamber x 6 x 10⁴

 Pressure of empty chamber = 20.5 torr

What is the scientific notation of 36000x10 ex.10?
Vedmedyk [2.9K]

Answer:

3.6 times 10^4

Explanation:

Scientific notation is between 1-9. So, we move 36000 to 4 decimal places. SO it would be 3.6 times 10^4. Scientific Notation always has the base of 10 . Enjoy :)
