Mass & Matter Chem Review

 1. Explain the difference between physical and chemical properties including providing examples.

    Characteristics that describe how something changes or fails to change are chemical properties and physical properties are characteristics that can be observed without the production of new characteristics.
 2. Explain the difference between intensive and extensive properties including providing examples.

    Extensive properties are properties based on how much there is of the object such as weight, and Volume. Intensive properties do not rely on how much of the object is there. An example of an intensive property is length, temperature, and combustibility.
 3. Explain the difference between chemical change (i.e. chemical reaction ) and a physical process

    For chemical changes, particles rearranged interact whereas for physical changes particles don’t rearrange.
 4. State the four observations for a chemical reaction.

    Permanent color change, formation of a precipitate, gas formation, odor, temperature change
 5. Differentiate between an element, compound, and mixture. There is a common flowchart that covers all matter).

    and element is a particle that can not be broken down, it is in the most broken down form that it can be. Compounds are made up of 2 or more elements and form a completely new particle. A mixture is formed by mixing two or more substances together to forrm a solutionv
 6. Differentiate between a heterogeneous and homogeneous mixture including providing examples.

    With heterogeneous mixtures, the particles stay separated and the eye can see the different substances. In a homogeneous mixture, the two substances combine to become one mixture and you can not see the difference in particles.
 7. Explain the three reasons why mixtures and compounds are different including how a homogeneous mixture is different from a compound.
 8. Differentiate between a solution (homogeneous solution), a colloid, and a suspension.

    In a colloid and suspension, the two substances don’t settle out while in a homogeneous solution it does.
 9. Explain the Tyndal Effect and how it relates to Heterogenous mixtures and homogeneous mixtures.

    The Tyndal Effect is when light beams become visible to the eye. This only works with heterogeneous mixtures and not homogeneous mixtures as particles are close enough together or big enough for passing light to be affected

  1. ==Be able to define compound and Temperature(exactly as I have defined them). Only definitions need to know verbatim.==

    ==average KE of all the particles in a substance==

    ==2 or more elements chemically combined in a fixed ratio==

  1. ==Define chemistry and understand the difference between pure and applied scientists.==

    ==the scientific study of the substance of the matter and what it is composed of.== pure science is learning for knowledge and applied science is taking that knowledge and using it to find cures and help others,

  1. State the 3 phases of matter and be able to explain how they are different from each other (including the Intermolecular Force issue) using the particle view of the matter.

    liquid, solid, gas. Solid has no energy to push against IMF, Liquid has enough energy to push against IMF so it takes the shape of the container it’s in, Gas has the energy to overcome IMF so it can move anywhere.
