1. In the lab, you accidentally discover a pure
substance that has a definite shape. It cannot be
compressed or “squished" to a smaller size. It has a
definite volume and doesn't
change shape when you put it iin
a new container. The molecules
within the sample are arranged
very closely together and don't
move a lot. What is this
sample's state of matter?

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
