Jordan Toschak Kevin Hannon and Megan Blanford Physical Properties of Clusters of Galaxies Monday (4/15/2013) Procedure For this experiment‚ a photograph of the Virgo Cluster of Galaxies will be needed to observe. The photograph will be sectioned into specific areas with coordinates like a map. Locate the area and identify the galaxies. Classify the galaxies as elliptical‚ spiral‚ or irregular. An elliptical galaxy will appear solid with not real defined “arms” or spirals coming from the

Some physical properties: transparency‚ flexibility‚ elasticity‚ permeability‚ water resistant‚ electrical resistance‚ Specific Gravity‚ soft when hot. Some chemical properties: solubility‚ chemical resistance‚ thermal stability‚ reactivity with water‚ flammability‚ heat of combustion. Resin refers to the basic chemical composition of each type of plastic. Each resin has unique properties and is used (often mixed with additional chemicals and materials) in the manufacture of a variety of plastic

Lab questions: 1. Based on my observation CaCl2 is soluble in water. 2. When 15% of HCl was added to CaCl2 as the teacher was performing the experiment I observed and realized some changes took place physically

Patrick Kelly 10/16/12 Physical and Chemical Changes Lab Question: How do you distinguish a physical and chemical change? Hypothesis: If we use these materials and use magnets‚ water‚ burners‚ and filters on the mixtures and elements given we should determine what kind of effect these materials given will have on these mixtures and elements‚ physical or chemical. Procedures: -Part A: Record all observations of Part A in Data Table 1 1. Label each substance on seven pieces of paper

Properties and changes are used to describe matter. A property is a trait of matter‚ when that sample of matter is in a fixed state. There are two different types of properties: physical properties and chemical properties. A change is something that alters the properties of a substance. There are two types of changes: chemical changes and physical changes. A physical property is a property that can be observed without changing the makeup (or composition) of a substance. Some examples of a physical

you observer any chemical changes in this experiment? Yes. CuCo2 turned green when I applied heat to it. B. What evidence did you use to decide that something was a chemical change? I viewed my other test tubes to see if it there was a chemical change in those. C. Give at least two examples of chemical changes you observed. Zn and MgO when I Diluted HCL D.
