Liquids and Solids

Density of liquids and solids Density is the amount of a substance contained within a specific area. Density is the mass divided by its volume and is expressed in units like grams per cubic centimeter or pounds per cubic foot. Density measured in units of g/ml is also known as specific gravity. Specific gravity is defined ... measurement. Subtract the weight of the container and you will have the mass of the liquid. The volume of a liquid can be determined by something as simple as a measuring cup used for cooking. From that point you would use the same method for liquids as you would for so...

... while those formed from transition metals are usually coloured The strong, electrostatic attractions between the oppositely charged ions in the three-dimensional lattice result in ionic solids being hard and difficult to cut. The brittleness of ionic compound results from the orderly arrangement of ions in a crystal being disturbed after a layer of ions is ... and many are liquids or gases at room temperature. They are non-conductors of electricity in both the solid and liquid states and the aqueous solutions of some compounds are weak conductors of electricity however few compounds in ...

... increasing the rate of reaction. Changing the surface area of solid reactants" This factor is also not relevant for this investigation since the reactants do not involve any solids. In reactions which involve solids, the greater the surface area the faster the rate of reaction because increasing a surface area of a solid reactant will expose more of its particles which allow more collisions ... to work out the rate of reaction for this experiment because this reaction is a precipitate reaction where tiny solids of Sulfur are formed which makes the solution cloudier. This method involves...

Expected mass of aspirin (g) = 0.0174 * 180 = 3.132g (d) Percent yield = ------------- X 100% (e) 1.0071 = ---------- X 100% 3.132 = 32.2% yield (to 3s.f.) 5.3 Melting Point Temperature range = 127.1° C to 134.2°C 5.4 Appearance It is white, odourless and needle-like solids. 6. Discussion: 1. Melting Point Determination For the determination of the melting point of a crystalline substance, a small amount of the finely powdered crystals is introduced into a thin-walled capillary tube. The ... acid was synthesized. 3. Safety Measures During the procedures, one should remember to avoid s...

... lattices. These polymorphous compounds change lattice when they are solidified at different temperatures and pressures. Polymorphous elements are called allotropic while their states are called allotropes. Now turning to liquids, liquids are unique in the way that while gasses can be easily blown apart by outside forces and solids are hard to, liquids move to accommodate the force. In other words, whereas wind generally doesn't break ... solids but can blow gasoline fumes away it would merely stir a liquid and then return it to its original shape. Similar to gasses, liquids diffuse easi...

... the container more often, and consequently the pressure goes up. The speed of the particles won't change so long as the temperature doesn't change. Furthermore, the kinetic theory can explain how solid, liquids and gases exist. In solids the particles are close together and the attractive and repulsive forces between each molecule are balanced. Solids therefore have a regular pattern, and don't fall out' ... of shape. In liquids the molecules are further apart than in solids and can move rapidly over short distances. In gases the particles are ... about 10 times further apart than in li...

... produce anything of use. Different hydrocarbon chain lengths all have increasingly higher boiling points and this property of crude oil means it can be separated using a process known as fractional distillation. Fractional distillation is a method of distillation, which is used to separate liquids from non-volatile solids, as in the separation of alcoholic liquors from fermented materials, or in the ... separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil. The process of fractional distillation i...

... Where gaseous chemical equilibrium are involved more than one gaseous substance is present. For example: aA(g) +bB(g) «cC(g) +dD(g) The equilibrium mixture contains two gaseous products (C and D) and two gaseous reactions (A and B).This is called partial equilibrium. B.

... solute are both determinants of the rate of reaction on the solubility of solids and liquids in water. A predominant trend is evident with an increase in temperature equating to an increase in the rate of reaction in solids and liquids within a solvent. Solute and Solvent Interactions The relation between the solute and solvent is very important in determining solubility. If the attraction between the ... solute and solvent is strong, greater solubility will occur. However, if the attraction between the solute and solvent is weak, it will result in lesser solubility ... solution back in...
