Give five difference between solid, liquid and gas on the basis of their properties |
|
Answer» liquids and gases are different mainly because of their lattice arrangements and the cohesive forces between the molecules. ... The cohesive forces between their molecules are ALSO very weak. This GIVES gases their PROPERTY to flow and compressibility.Gases, liquids and solids are all made up of atoms, molecules, and/or IONS, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular ARRANGEMENT. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.Liquids have less force of attraction between molecules than solids and more than gases; gases have a very weak force of attraction between the molecules which is the least amongst the three states of matter. |

Calculate the no of ions of AlF3 in two moles? |
|
Answer» A 0.21 M solution of ALF contains 0.21 moles of molecules for each liter of solution. In this problem we have only 65.5 mL (0.0655 L) of solution, so the number of moles is 0.21M×0.0655L=0.01376mol .Ionization of each AlF unit produces one FLUORIDE ion ( F− ), so the number of moles of fluoride ions is the same, 0.01376mol . As the other contributors have POINTED out, the correct FORMULA for aluminum fluoride is AlF3 , and in this case, each formula unit would produce three F− ions.Finally, to obtain the actual number of ions, we multiply by Avogadro's number:0.01376mol×6.022×1023mol−1=8.28×1021or, in the case of AlF3 ,3⋅0.01376mol×6.022×1023mol−1=2.48×1022 |

Difference between homegenous and heterogeneous mixture |
|
Answer» A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. ... All solutions would be considered homogeneous because the dissolved material is present in the same AMOUNT throughout the solution. One CHARACTERISTIC of mixtures is that they can be separated into their components.A HETEROGENEOUS mixture is a mixture in which the composition is not uniform throughout the mixture. ... A heterogeneous mixture consists of two or more phases. When oil and water are COMBINED, they do not mix evenly, but instead form two separate layers. Each of the layers is CALLED a phase |
