I am working on this Science Fair Project about how different soils are affected by erosion. I have done the question, hypthesis, and the experiment, but I don't know how to show the data. What should I put as the data? PLEASE HELP! This question is worth 21 points, and the best answer will get a BRAINLIEST. :)

Which compound contain an iron with a 3+ charge

Which statement about the relationship between laws, hypotheses, and theories is true?

Which statements correctly match a chemical name with its formula? use the list of polyatomic ions and the periodic table to you answer. the chemical formula for ammonium carbonate is nh4hco3. the chemical formula for ammonium hypochlorite is nh4clo. the chemical formula for ammonium nitrate is nh4no3. the chemical formula for ammonium phosphate is nh4(po4)3. the chemical formula for ammonium sulfate is (nh4)2so3.
