The pK₂ of methylamine is3.36. Calculate the pH of the base solution after the chemist has added 33.6 mL of the HIO3 solution to it.Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HIO3 solution added.Round your answer to 2 decimal places.3XOxOolo

TripAdvisor 33 of 40 I Review | Constants | Periodic Table Learning Goal: To become familiar with the concept and calculations of specific heat. Part A Specific heat (which can be represented as SH, Cs, sp. ht., or a number of other possibilities) is defined as the amount of energy needed to raise the temperature of 1 g of a substance by 1 °C. For example, 0.0920 cal is enough energy to raise 1 g of copper from 21.0 °C to 22.0 °C. Therefore, the specific heat of copper is 0.0920 cal/(g - °C). How much heat energy is required to raise the temperature of 0.360 kg of copper from 23.0 °C to 60.0 °C? The specific heat of copper is 0.0920 cal/(g- °C). Express your answer with the appropriate units. > View Available Hint(s) Using SH for specific heat, the formula for calculating specific heat is HA Value Units heat heat = SH = massxAT P…

For example, CHCIBII is chiral, but CCl,BrI is achiral because some of the bonded groups are the same. If a chiral carbon atom is present, then that molecule has a non-superimposable mirror image called an enantiomer. (Figure 1) Part A Identify all the chiral atoms in the below structure by right-clicking* a chiral atom to bring up a menu that includes "Atom Properties." Click on Atom Properties then click the checked box next to the Map field to clear the checkmark. Then enter "1" in the Map *Mac users: Use an equivalent for right- field box to label that chiral carbon atom. clicking.…
