Europa2433 this isnt for a test, quiz, or homework, its for self guided notes that the teacher wont even look at, so please stop deleting it. i'm just looking for some help

1. Considering the structure of the atom (our 2nd unit of Chemistry) what location of the
atom do you think nuclear chemistry deals with?
2. Look at the periodic table image in the notes (also use your own periodic table that
shows more information). What can you say about the size of the majority atoms
described as radioactive (colored purple on the periodic table image)?
3. What 2 features of nuclei make them likely to be radioactive?

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
