I learned a lot about how molecular formulas are made. It told me a lot about moles. It helps us understand wher ethe numbers are coming from.

I learned about cation and anion ratios. I also learned when u mix the different solutions they turn different colors..well white during this lab. I also learned about the ratios of elements in the compounds.

I learned that chemicals can change color and then disappear in color. It was pretty cool. All the compounds turned white by adding some type of chemical.

I learned that if you mix different substances they change color. I learned how molecular formulas are made. I learned more about moles what happens with them.

in the lab that we did today, i learned that chemicals change colours when they're mixed together. it's a pretty interesting experiment thing. we also learned about the rations of elements in the compounds, in our way, it looked like milk today, and it was supposed to be pinkish colours! =)
