experiment were to determine the densities of some solids and liquids and to apply the rules of significant figures in computing laboratory data. For liquids‚ a dry‚ empty 100-ml graduated was weighed. Fifty ml of water was placed in it‚ then weighed again. The same was done for other liquid samples. The mass of the liquid sample was determined by subtracting the mass of the empty graduated cylinder with the mass of the cylinder and liquid. For the density of solids‚ the rectangular block was weighed

insoluble solid. 3. Decantation. This separates a liquid from an insoluble solid by carefully pouring the liquid from the solid without disturbing the solid. 4. Filtration. This separates a solid from a liquid through the use of a porous material as a filter. Paper is a good filter. Filters allow the liquid to‚ pass through but not the solid. 5. Evaporation. This is the process of heating a mixture in order to drive off a volatile liquid and make the remaining component dry. The mixture

jar in a sunny spot.) Strain the mixture through a coffee filter or paper towel. Leave the strained alcohol in a small covered dish. When the alcohol evaporates‚ the remaining liquid is the orange oil. Mix the orange oil with the Styrofoam. The Styrofoam will then break down into a thin liquid form. Take the resulting liquid‚ which will amount to an orange scented glue and pour into a jar. Label it well as "Glue" before you put it away‚ so you and your household will know what it is later. D.

What happens when a sugar lump dissolves in water? When the sugar dissolves... -The moving water molecules crash into the sugar particles -The sugar particles then break away from the crystal and into the water -The sugar and water particles then mix and diffuse evenly throughout.

DETERMINING A LIQUID ’S VISCOSITY USING MARBLES An Investigatory and Exploratory Project In Partial Fulfillment of The Requirements in Chemistry ABSTRACT The project is all about viscosity. Viscosity is a very important quality of liquids that scientists‚ engineers‚ and even doctors are frequently trying to measure and change. It is difficult‚ for example‚ to transport highly viscous crude oil through offshore pipelines‚ so scientists and engineers

presence of fat. However in this experiment‚ not only are the milk tested for its composition‚ the amount of the particular substance such as reducing sugar‚ protein and fat is also tested by observing the intensity of the colour change. Milk is a white liquid produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest other types of food. Early-lactation milk contains colostrum‚ which carries the mother ’s antibodies to the baby and

DENSITY OF LIQUIDS AND SOLIDS by Lab instructor: Due date: Results and discussion: The purpose of the experiment was to determine the densities of the unknown liquid and solid as precisely and accurately as possible in order to identify them. It was carried out first on distilled water in order to rule out systematic errors. A 10 mL beaker was placed on a top pan balance and “tared”. The beaker was then removed and 10 mL of distilled water was pipetted into it before it was placed
