Pour 50 ml of water at room temperature into a 50 ml graduated cylinder.
Measure 1.5 g of sugar in a medicine cup with an electronic scale.
Transfer water from the graduated cylinder to a 250 ml beaker.
Pour the 1.5 g of sugar into the beaker and stir with the stirring rod.
Use stopwatch to record the time it took when the sugar is completely dissolved. Stop the experiment at 1 minute and 30 seconds if the sugar does not dissolve.
Record the experimental result on the data table after each solvent.
Repeat steps 1-6 with the rubbing alcohol and vegetable oil instead of water.
After conducting the experiments, clean up your workspace.
After added, pick up the beaker and swirl it around lightly for a short period of time.
Start with a clean and dry 100 ml plastic graduated cylinder. Add M&Ms until the graduated cylinder is about 3/4 full. Gently tap the graduated cylinder to "settle" the M&Ms. Read the volume of M&Ms in cm3 and record the value in Data Table 1.
Hypothesis: Altoid and Smarties will dissolve the fastest and Sweet tarts will dissolve the slowest.

1) Pour 25 mL of the 1 M hydrochloric acid into the beaker and rinse the solid by swirling the acid around in the bottom of the beaker.
lab bench. Place a beaker from the drawer on the stir plate. Drag the bottle of NH3 to the 5 mL graduated cylinder (the smallest one) by the sink and fill the cylinder by dropping the bottle on the cylinder. Now drag the 5 mL graduated cylinder to the beaker on the stir plate and add the 5 mL of
Measure the correct amounts of sugar and water into each of the labeled cups. One at a time, place a cup on the scale and add the sugar directly, but before you do so, hit the button “on” or “zero” to restart the scale. This way, the scale will only measure the amount of sugar that is poured into the cup and not the cup itself. The chart shown below will tell you how much sugar to weigh in each cup. Once you have finished, add 50 mL of water to each cup using the graduated cylinder. Then stir your cups with the spoon until the sugar has dissolved in each solution.

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?
10.For glaze, combine powdered sugar and milk in a small bowl and stir until smooth.
3.Measure and add 0.5g, 1.0g, and 1.5g of sucrose into 3 of the test tubes. Do not add sucrose into the 4th test tube because this will be the control. Lightly shake the test tube to mix the contents together.
C) Again, rinse the saucepan and then add 250 grams of sugar to your 250ml graduated cylinder and then add water up to the 250ml mark. You will place a small piece of plastic wrap over the top of the graduated cylinder (or parafilm if you have that), and mix the sugar with the water. Then pour the contents into a small saucepan over the stove. You will fill the graduated cylinder up to the 250ml mark again and then pour the tap water into the saucepan as well. You will now heat the mixture on the stove and stir until the sugar has dissolved. Once this has happened, you will remove the solution from the saucepan, pour the solution into a container and label that container 50% sugar solution.
The correct syringe is used to place 10 cm3 of the first glucose solution into the boiling tube.
5) 5 mL of sugar was added to the solution and a balloon was placed over the opening of the bottle to minimize the loss of any gas from the system.
Ensure that the sugar has completely dissolved. Remove the pan from the heat, cover it with a lid and allow it to steep for 20 minutes.
