Scientific method and atomic structure add a co option 1: we will begin this topic by practicing the use of the scientific method. the steps of the scientific method are: observation, hypothesis, experiment results, and theory. using your understanding of the scientific method from your readings and lessons, you will be applying this knowledge to a real world situation. take a real world scenario in the news, or another outside source and apply the scientific method, being sure to detail the controls on your experiment. describe a result that would confirm your hypothesis • media option 2: choose a scientific paper written in the last year. the chamberlain library is a great source for this. for your chosen paper, look into the study and discuss how the scientific method was used in this paper. be sure to note they hypothesis, variables, results, etc. based on your understanding of the scientific method, be sure to discuss if you find this paper as a trustworthy top

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback

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.
