PURPOSE The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance. PROCEDURES 1. Separating out the Iron a. Use your digital scale to determine the mass of your weighing dish. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal

flask Method: 1) 2.4g to 2.5g of sulphamic acid was weighed out‚ firstly by weighing the container and the sulphamic acid together‚ then pouring the sulphamic acid into a beaker. The container was then weighed again and the initial weight and the weight of the container alone were subtracted from one another to provide the mass of the sulphamic acid. 2) The sulphamic acid was then dissolved in 50cm³ of distilled water‚ using a glass rod to ensure it is completely dissolved. 3) Using

driven off‚ because water is loosely bonded to the hydrate. Procedure 1. Set the necessary lab equipment properly. 2. Weigh dry and clean crucible and its cover on the balance. Record. 3. Measure about 1 to 2 grams of the hydrate and record the weight using the weighing boat. 4. In moderate flame‚ heat the empty crucible with tilted lid for 3 to 5 minutes. Record what happens during the heating process. After recording‚ wait for crucible and lid to cool‚ and weigh‚ and record. 5. Repeat step 4

I. Introduction a. Reach back‚ rotate the hips‚ let the upper body follow‚ push out the arm‚ flick the wrist and release. These are the basic step to the power throw in shot put. While shot put may seem like a sport based simply on upper body strength‚ there is much more too it. As stated by the Live Strong foundation‚ you need to focus on core and leg strength as well as focusing more on power than strength (Flaherty). It is also crucial to make sure that you are using the correct form.

nearly impossible to get the exact measurements of items with irregular shaped surfaces manually. 4. It is important to dry a wet object before finding its mass because if you weigh it when it has water on its surface‚ the extra weight of the water will make the weight measurement invalid. 5. You should tilt a graduated cylinder when you drop in objects because if they drop directly into the water‚ they might make a splash and displace some of the water‚ that is measuring the volume of the object

single it out from the other substances which do not respond to a magnet. a) Use scale to find the mass of your weighing boat. Then pour the mixture of solids into the boat and weigh it again. Then find the net mass of the mixture by taking the weight of the weighing boat and mixture and subtracting the mass of just the weighing boat. b) Spread mixture into a thin layer on a sheet of paper. Cut the second piece of paper into a 10-cm square‚ weigh and record its mass. c) Cut the plastic into

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that
