Science Homework Help

I’m working on a chemistry discussion question and need an explanation to help me learn.

This week there are only 2 problems. The answers provided are wrong…very wrong. Skip the rubric. An additional question is in a separate doc file with no answer provided and you need to answer it. If you choose not to answer that question and only answer the 2 wrong problems, you will get 50/100. So make sure to answer them all!
