- Water and rubbing alcohol have distinct properties and will react differently with the same substance. Observe these properties of water and rubbing alcohol: color, smell, and ability to dissolve salt. Record your observations in the table. To observe the solubility of salt in the liquid, put one-quarter teaspoon of salt into each container and stir. You may weigh out 1.5 g of salt on the electronic balance if you don’t have a one-quarter teaspoon measure. Observe the properties of the liquid in the container labeled unknown. Record the properties of the unknown substance in the table. Now observe the properties of the liquid in the container labeled unknown. Record the properties of the unknown substance in the table.

Which of the procedures would be the most effective way to separate the sugar from the tiny pieces of glass? Collect all of the sugar and glass pieces into a pot and heat the mixture to melt the sugar. Then, pour the liquid sugar through a filter to separate the glass from the sugar. Collect all of the sugar and glass pieces into a bucket of water. Allow the water to dissolve the sugar, then remove the water and sugar solution, leaving the glass behind in the bucket. The solution is then heated to evaporate the water, leaving the sugar behind. Use a magnifying glass and tweezers to safely remove the glass particles from the mixture. Sweep a magnet across the spill to attract the glass particles and remove them from the mixture.arrow_forwardWe are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are: What law or principles of chemistry could be applied in this experiment? Should we expect the temperature of the hot water to drop? why? Should we expect the temperature of the water to rise or drop after putting the ice? why?arrow_forward
- The density of a substance can change with temperature. The graph displays the density of water from -130 °C to 100 °C. Examine the graph and answer the questions. Water undergoes a large change in density at 0 °C as it freezes to form ice. Calculate the percent change in density that occurs when liquid water freezes to ice at 0 °C. final value - initial value (Hint: % change initial value × 100%) The Density of Water as a Function of Temperature 1,010 1,000 990 980 970 960 950 940 930 920 910 -150 -100 -50 50 100 Density (kg/m)arrow_forward[References] Superconductors are materials that have no resistance to the flow of electricity, and they hold great promise in many engineering applications.
