Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility

Name: Tom Flannigan Title: Physical and Chemical Properties Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

Performed: 04/02/14 Date Submitted: 04/15/14 Name: Lisa Jacoby Title: Physical and Chemical Properties Purpose: Investigating the chemical properties of pure chemical substances as well as exploring the physical properties of pure chemical substances Procedure: 1. I half-filled one well of a 24-well plate with 6M HCl and half-filled a second well of the 24-well plate with 6 M NaOH. I then sucked up these chemicals into their labeled pipets. I then set aside for later 2. I performed

Physical and Chemical Properties Chem 107 6-4-2013 A pure substance or chemical substance is a material that is homogeneous. It has consistent properties throughout the sample.” Pure substances can be described by both physical and chemical properties”. Physical properties can include‚ color‚ odor‚ melting point‚ boiling point‚ and solubility in various solvents‚ etc. The observation of these physical properties does not involve any chemical change in the substance‚ it is still the same

PHYSICAL SCIENCE physical change-changes affecting the form of a chemical substance‚Physical changes are used to separate mixtures into their component compounds Example:breaking glass Chemical changes- when a substance combines with another to form a new substance ‚called chemical synthesis. Example: burning wood Law of Conservation of Mass-The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations

I am going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab‚ I will study how digestion of carbohydrates‚ proteins‚ and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical

Soil properties: Some physical and chemical properties of the soil were measured‚ which are presented in Table 1. The availability of nutrients and even contaminants depends on the degree of soil acidity. The most suitable pH for soil microorganism’ activity is 7‚ as nutrient solubility depends on soil pH changes (Riser-Roberts‚ 1998). The soil used in the present study has neutral pH and therefore does not limit the activity of microorganisms or the solubility of nutrients except for phosphorus
