Week 19 ( attempt number two)

 The blogger app ate my first draft of this post!  I hate technology sometimes, I'd rather be a ludite, honestly, but alas I was born in a time where i grew up with computers, i didn't see them  come into being.

Week 19

Happy Sunday!

Unfortunately we had no school on fiday due to imcliment weather ( YAY!) and so it is acceptable to assume we have an assesment monday. ( Not as excited about this part.)

This past week we started applying Dalton's theory of diatomic molecules and finding out which elements were diatomic ( such as Hydrogen and Chloride) and  which were not. The theory is useful in figuring out chemical equations if you know which molecules contain two atoms instead of one. We conducted an experiments this week  to prove if Cloride is a diatomic element and we mixed hydrocloric acid with zinc in a flask, and as a result clollected some combustable gas and water vapor. The oxygen in the air reacted with the hydrogen in the air creating water vapor and the other byproduct of this chemical reaction was zinc oxide.

  1. This is barely a recap of what happened in the week; this is supposed to be a reflection on what happened, which requires (at the least) a summary of the activities and ideas learned.

    Your future posts can be improved by adding even more details or insights to what happened during the week, or adding photos, video or URLs to relevant websites that connect to what we did in class. Consider writing more about what was easy for you to learn/understand, how ideas went together, or what might have made some concepts a struggle for you in all the activities we did.
