Observation and Results: Photo is of my constructed incubator without the tin foil. I have opted to place the incubator on top of my fridge‚ hoping that this would lead to less disturbance and curiosity from others in the household

CaCl2*2H2O)(1mol Na2CO3/1mol CaCl2*2H2O)(106g Na2CO3/1mol Na2CO3) = 0.72g Na2CO3. The final‚ when its dried in the paper filtered weighed at 1.6 grams. Experiment and Observations: As I performed the lab‚ I had to retrieve all my equipment’s from my labpaq. As I started to setup‚ I had to weigh out 1.0 gram of CaCl2*2H2O on the digital scale. After it was weighed‚ it was added to the 100 mL beaker and 25 mL of distilled was added and stirred. Next‚ I had to figure out the amount of the second reactant

Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The learning goal of this experiment is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin? What precautions does one have to take to work with this chemical? Acetamide is a carcinogen‚ which can cause cancer. Therefore‚ it should not be allowed to come in contact with a person’s skin. Any person working with this chemical

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

Properties of Gases CHE101 Experiment date: 06/20 Write-up date: 06/21-06/22 Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid‚ mossy zinc‚ Bromothymol blue‚ limewater‚ Manganese‚ and Alka Seltzer‚ to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar‚ baking soda‚ water

The Endocrine System Exercise 1: The Pituitary Gland obseRvations A. Please describe in detail the structures and features you observed on the pituitary gland slide. The Pituitary Gland Slides The Anterior Pituitary Gland was darker than the Posterior Pituitary Gland. In the Anterior Pituitary Gland Slide you can see Chromophobes and Acidophiles. Not super easy to distinguish which is which though. The Posterior Pituitary Gland slide showed Pitulcytes (Neuroglia) as light purple

Lab Report 2 Observations of Chemical Changes Objectives: (1 of 20 points) The objectives of this experiment are: 1. To observe some properties of chemical reactions 2. To associate chemical properties with household products Background Information: (2 of 20 points) Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature‚ presence of a flame‚ and evolution of light‚ as when as firefly glows. Three physical changes that
