Are the following water-soluble substances are strong acids, strong bases, or neither (a neutral salt)? Hint: can you use a chemical equation to determine the ions in the solution? (a) NaOH(s) The dissociation of NaOH increases the concentration of ---Select--- hydronium / hydrogen ions hydroxide ions neither hydrogen nor hydroxide ions in the solution. These ions can ---Select--- accept protons from donate protons to the solution, forming water. Therefore, NaOH acts as ---Select--- an acid a base neither an acid nor a base . (b) RbClO4(s) The dissociation of RbClO4 increases the concentration of ---Select--- hydronium / hydrogen ions hydroxide ions neither hydrogen nor hydroxide ions in the solution. Therefore, RbClO4 acts as ---Select--- an acid a base neither an acid nor a base . (c) HNO3(l) The dissociation of HNO3 increases the concentration of ---Select--- hydronium / hydrogen ions hydroxide ions neither hydrogen nor hydroxide ions in the solution. Therefore, HNO3 acts as ---Select--- an acid a base neither an acid nor a base .

During meiosis II, how does the chromosome movement differ than mitosis? Group of answer choices Whole chromosome pairs move to one pole or the other Only one cell is made in meiosis so the chromosomes all go to one cell and not the other There is no difference between meiosis II and mitosis in terms of chromosome movement All chromosomes move to one side or the other, so each cell gets half of the DNA

In the MinnLand dataset in the alr4 package, fit two possible models with log(acrePrice) or sqrt(acrePrice) as the response, use year as a factor as well. We want to revisit the setting where we need to better understand land prices and the drivers. Use methods we’ve learned to develop two possible candidate models and compare them using 5 Fold Cross Validation 10 Fold Cross Validation Random Splitting with 1000 splits. Note you should use parallel computing where you can/need, and function writing where you can/need because there are 18,700 observations. Before starting this analysis remove ALL NA's from the data using na.omit(MinnLand). In each of the above cases comment on the model you would select to present as your final model based on prediction accuracy. Give any insights it may have on the land prices in Minnesota over this time frame.
