Week 11- Gene Therapy

Seems there is a lot to say and a lot of opinions..If someone or myself especially had a life-threatening illness and benefits outweighed the risks as in some examples mentioned, I think it would be great. There are just so many diseases we don't know enough about to be injecting large amounts of DNA into the human body. I am all for doing the research and feel it would be better if your body could be injected with the gene instead of taking a medication with a million side effects:)

Week 10- Semiconductors are cool, Too!

SILCON is the one!!

Si...symbol

14...atomic number

-not very often in it's free element form, but the

-8th most common element in the universe by mass! Yes!!

- Forming glasses, cements, and ceramics, it is the most common metalloid used:)

Week 10- Chembalancer Fun Learning

Well, easiest quiz for me was the element quiz. Fun and I learned some interesting facts! Surprised I remembered some of them from class! (and it wouldn't let me to the English "Word Ruffle", although I guess I was supposed to stick with the chem ones anyway;)

Week 10- Balancing Chemical Equations

Well, I thought the article would be a little boring, but it seems cool (and very difficult) to be able to remember or recognize what a phosphate or nitrate would look like, as they said not to mess with these! The reacting equations were also pretty cool...reactants reacting, then the products reacting..then back and forth until it was stable..at least that was my understanding!!!

Week 7- Hypothesis/Avogaro's number

Seems hard in science because scientists are so skeptical that once a theory was/is established and well-known, for someone to come in and give a different hypothesis was often not accepted for awhile. Avogadro is a big example of this. Dalton rejected his hypothesis because they thought only unlike atoms could be held together. Although Avogadro proved this to be false, he died in 1854 without anyone of the time knowing his name...

Week 7- Alkaline Earth Metal

just curious about calcium..all alkaline earth metals have an oxidation number of 2, making them very active!

Week 7- What is a Mole?

What is a mole is somewhat complicated..this article mentioned it was just something to confuse future generations! Basically because molecules and atoms are so small, the number gets too big when talking about how many grams there are. The standard is based on the carbon-12 isotope. So, the standard of a mole is used, as it is NA x (mass of carbon-12 atom)= 12 g.
