#3) Describe the difference between chemical and physical properties and changes of matter? How do these physical and chemical properties relate to intrinsic and extrinsic properties? How are these properties related to the different states of matter? Lastly, how might one classify these different types of matter? Make sure to provide examples of each.

Paragraph Styles Editin 4 7. You preform a variety of chemical/physical changes and separations every day. Give a total of four examples in your home and label what kind of change it is. You must have at least one separation, physical change, and chemical change. (check out the power points slides on the properties of matter for inspiration on this). (8 points) D. Focus a о 8 9

Many of the water properties lead to some crucial physical, chemical and biochemical processes that are closely related to environmental and health problems. Some people state: (I) A relatively high dissolution of O2 in water is due largely to the dipolar property of water molecules. (II) Although the density of water changes only slightly with temperature, its change can cause lake water turnover or stratification. (III) Since water dissociation is so small (H2O ó H+ + OH-, Ka = 1.0...
When melting or boiling a substance (both of which are physical changes), which kinds of attractions may be broken? Circle all that apply. dipole-dipole London forces covalent bonds hydrogen bonding он но. Vs. If I told you that only one of these molecules is a solid at room temperature, which one is that more likely to be? How can you tell from the structure? Circle the hydrophilic portion of the molecules above and put a box around the hydrophobic parts....
As early as 400 B.C., Greek philosophers proposed that matter was made up of particles. During the 1800s, John Dalton linked the idea of atoms with the chemical identity of an element. His atomic theory of matter involved the following postulates. 1. Each element is composed of extremely small particles called atoms. 2. All atoms of a given element are identical to one another in mass and other properties, but the atoms of one element are different from the atoms...
