  1. My goal is to stay prepared and ahead of what is about to happen in any of my classes. I have been doing that pretty well lately with the routine I created.

  2. If an unknown material is ductile and is malleable, what type of element would it be?

    The material would be a metal as nonmetals are brittle, noble gases aren’t solid which means they can’t be ductile, and metalloids are less malleable than metals.

  3. why is it necessary to know the latin names of the elements?

    Because in some stores they still use the latin name of the elements on the bottle label.

  4. What is the importance of knowing the element symbols along with the elements?

    Knowing the symbol for the elements allows you to not have to write the whole word out. Also scientist use the symbols when writing the names of substances for example instead of writing 2 Hydrogen atoms and one Oxygen atom scientist just say H2O.

  5. When a paper cup is heated with fire it burns, but when a paper cup filled with water is heated with fire it does not burn. Why?

    When the heat was only directed towards the paper cup without water, it quickly reached its melting point and burned up quickly. The paper cup with water did not burn up because it had not reached its melting point. The heat energy from the flame was transferred from the cup to the water inside the cup, so instead of the cup burning up, the water started to heat up.

  6. What is the importance of chemical properties?
    Chemical properties are important because they can be used to identify unknown substances or building chemical classifications.

  7. Isn’t technological development actually a form of applied research? Yes because as technology progresses, we are able to solve more complex problems.

  8. Why do we need to learn chemistry?
    If we end up having a job that deals with chemistry will will need to know the basis and what everything needs.

  9. Why do we need to learn chemistry?
    If we end up having a job that deals with chemistry will will need to know the basis and what everything we need in that class.

  10. How is the periodic table organized?
    The periodic Table is arranged from from left to right in increasing atomic numbers.

  11. this week my question was what is the purpose of the periodic table other than just some fancy organizing. by the end i learned that it’s really just a way for scientists to communicate and understand all the elements universally

  12. Is learning chemistry important? It is absolutely important to understand the world around you, and I think it also is important because it applies to so many fields of study, as we saw in this past chapter.

  13. why are some elements said to be a solid and can be in a liquid state?

    Because the element can change its state by the temperature in a room or the physical state it’s alright in.
