Chemistry 1-19-21 Chapter 7 Test Overview

CHEMISTRY: God bless you as you study! Here’s our overview of the test from today and a look at some chemical names and formulas. Did you find the Chapter 7 Stuff to Know sheet? Be sure and use it as a road map for your studying. I know it seems like a lot, but you can do it!

First priority – make sure that you have memorized EVERYTHING. Then, practice!!! Go to sciencegeek.net and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on sciencegeek.net. That’s always some good practice. And don’t forget about polymers!

I’ll be praying for you! You can do it!!

  1. Heat resistance for exit and re-entry of the atmosphere and weight are both issues for space travel. Metal is used commonly on spacecraft because it is heat resistant, but it is heavy. Plastics can be much lighter than metals. Could a thermoplastic be developed that is heat resistant enough to be used on a spacecraft to reduce weight? This could make it significantly easier to leave Earth.

  2. Q: Why would polyethylene be considered recyclable but styrofoam is not?
    A: Polyethylene is a high density polymer meaning it is thermoplastic, allowing it to more easily melt.

  3. Q: Heat resistance for exit and re-entry of the atmosphere and weight are both issues for space travel. Metal is used commonly on spacecraft because it is heat resistant, but it is heavy. Can plastic replace metal on spacecraft in the future?
    A: Yes, thermoplastics are being developed that are light weight and heat resistant enough to replace metal.
