Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 HNO, (Choose one) NO2 7 OH (Choose one) HF (Choose one) ▼

Given the enthalpy of formation data in the table below, what is the enthalpy of reaction for the reaction you performed in this lab? How does this compare to your experimental results? To calculate the enthalpy of reaction, use the formula below. AHran=EAH; (products) - EAH; (reactants) ΔΗ, Note that you will need the balanced chemical equation for the reaction performed in the lab, which can be found in the Background in your Hayden-McNeil course site. Also note that AHⓇ for standard state elements is 0 kJ/mol. Substance AH₁ (kJ/mol) MgCl₂(aq) -785.1 kJ/mol HCl(aq) -167.2 kJ/mol
