Here are 3 things  i learned about this chapter .The first thing  i learned this chapter is that a chemical and physical change are not the same.The second thing  i learned this chapter is that an acid is not as strong as a base on the Ph scale.The 3rd thing  i learned this chapter is that an indicator changes colors to the level of acidic.The thing that i liked most about this chapter is the chemistry in a bag lab.The thing that i didnt  like the most about this chapter is all of the confusing things.My question is how many vocab words did we have this chapter?
