I'm very confused Valine is an amino acid that can take on many protonated and unprotonated forms. It has a weakly acidcarboxylic acid group (pK, = 2.32) and a weakly basic amine group (pKa = 9.62).Identify which of the forms below would likely exist at the given pH values.H2N*H3NОНStructure AStructure BH2N*H3N.O.ОНStructure CStructure DWhen the pH = 1.00, [ Select ]predominates.When the pH = 5.00, [ Select ]predominates.When the pH = 12.00, [ Select]* predominates. A 6.8 L sample of helium gas stored at 25 °C and 1.00 atm pressure is transferred to a 2.4 L tank andmaintained at a pressure of 2.37 atm. What temperature (in °C) is needed to maintain this pressure?

Interpretation: The pKa value of carboxylic acid group in value is low. This means that it is highly…
